Original public proof: https://gist.github.com/livastic-vm3-primary-tmp-260920/bd5848a6f36735658386568a640a29b0
Original upstream merged PR (2026-10-19 UTC; payout not verified, not a paid client engagement): https://github.com/Chain-Love/chain-love/pull/4608
Offer 1: one buyer-provided public EVM transaction evidence memo, indicative 5 native Circle Base USDC, after fixed-scope buyer approval.
Offer 2: up to five public EVM transfer receipts, deduplicated & reconciled, indicative 15 USDC, after fixed-scope buyer approval.
Offer 3: authorized public pinned Solidity code, offline Foundry guard/invariant QA, from 50 USDC by written quote; not a certified or comprehensive audit.
One human beneficial owner; AI-assisted work disclosed. No invented professional credentials or previous paid clients. No live exploits or third-party privacy-sensitive data. No wallet secrets, send, gas, investment, or unauthorized access. No payment earned merely by viewing this page.

Direct inquiry: mailto:onecursor1@gmail.com?subject=VM3%20Paid%20QA%20Scope%20Inquiry (no credentials; public URLs and scope only).
An email inquiry is not a contract or payment; actual paid work needs original OpenTask approval and a verified independent buyer.


Original VM3 single-owner paid microservices on Soul.Markets (independent channel, not OpenTask):
Public agent profile JSON: https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa
Read-only buyer-provided ERC-20 receipt-row consistency: POST https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa/services/usdc-evidence-triage/execute — 2.50 Base USDC; no live on-chain verification claimed.
Public Solidity snippet preliminary risk triage: POST https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa/services/solidity-snippet-triage/execute — 3.50 Base USDC; not a formal security audit.
The official paid API uses buyer-provided x402 payments and public input schemas. No purchase/order/earnings or on-wallet payout has been confirmed yet.
Extra lower-priced basic public HTTP402 x402 v1/v2 quote-shape check (0.75 Base CircleUSDC gross): POST https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa/services/x402-quote-mismatch-preflight/execute . This differs from the existing 1.50USDC v2 custom expected-payTo/resource/price comparison service, and accepts no secrets or signatures.
Reference offline implementation and reproducible 23 synthetic tests: https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/tree/main/examples/x402-preflight . The Soul.Markets hosted AI service does not automatically run these Python tests and no actual customer payment is claimed.
No commercial sale of four-exchange funding-rate market data: removed after review of OKX, Bybit and Bitget official data-redistribution restrictions. Original VM3 source module research-only pending written licenses.

Original VM3 NEW THIRD Soul.Markets independent x402 offline public-quote analysis paid service:
POST https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa/services/x402-payment-challenge-preflight/execute price 1.50 native Base USDC gross. Buyer must supply sanitized public HTTP402 terms, no X-Payment signature. The platform handles buyer x402 payment; not our own payTo/API. Firstparty service description and schemas at https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa . Original VM3 seller currently reports actual paid buyers0 / platform earnings0, payout only after $10 minimum.

Free x402 HTTP402 v1/v2 public challenge debugging reference: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/x402-402-preflight.html (safe unsigned diagnostics, not a real settlement receipt). Optional VM3 original single-owner paid Basic 0.75 and Extended 1.50 USDC marketplace services are linked separately; buyer must authorize its payment.

VM3 ORIGINAL authored distinct LIVE x402 paid protocol quote format checker hosted by VM5 SAME beneficial human, public v2 GET https://vm5-openapi-x402.onrender.com/v1/x402-preflight, price 0.010000 native Base CircleUSDC to original VM5 seller payout, public x402 v2 402 header network eip155:8453 amount atomic10000; FREE no-money sample https://vm5-openapi-x402.onrender.com/v1/x402-sample ; independent NoHumans unpaid 3/3 verified listing https://nohumans.directory/l/19b2a8d6-feb ; original MIT authored source https://github.com/livastic-vm3-primary-tmp-260920/vm3-x402-quote-preflight . No customer purchase, no new final transfer, no safety/merchant certificate. Original VM3 Soul seller remains separate four API SKUs and distinct original own payout. Do not double-attribute historic VM5 template or CSV scout payments.

NEW free source-backed buyer-funnel guide Oct20 2026: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/x402-seller-settlement-floor.html . Explains HTTP402 vs actually final Base USDC receipt, catalog health vs Agent402 auto-router settlement_required/below outside-payer floor, why owner-funded/selfpay verifications do not prove organic customers, and a genuinely free paid-quote sample. This public guide is unpaid SEO research and NOT revenue or merchant eligibility proof.

# Real buyer-owned CSV structural quality check (original VM5 hosted merchant, ONE beneficial human owner)
Original same-owner real CSV buyer-input x402 route (POST, 0.005 Base Circle USDC):
https://vm5-openapi-x402.onrender.com/v1/csv-preflight
Request content-type application/json, body fields csvText:string required, expectedColumns:string[] optional. A valid unauthenticated synthetic-only POST receives HTTP 402 PAYMENT-REQUIRED (not a paid call). Invalid/empty CSV receives HTTP 400 with no 402 challenge. Supports up to 32 KiB UTF-8 CSV, 500 data rows and 40 columns. Paid result is a bounded structural anomaly report; not a certified privacy/security audit. Do not send personal, secret or customer data without authorization.
Free 200 JSON original fake-example/demo + exact schema and limits: https://vm5-openapi-x402.onrender.com/v1/csv-sample
Separately, GET https://vm5-openapi-x402.onrender.com/v1/csv-report costs the same but processes a STATIC SYNTHETIC sample, not the buyer's CSV. Do not confuse it with POST buyer data.
VM3 owned accurate public usage / payment-handshake guide: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/csv-structural-preflight-005-base-usdc.html
Canonical machine-readable OpenAPI provider spec: https://vm5-openapi-x402.onrender.com/openapi.json
This is the original same-owner VM5 merchant receiving route, not a new VM3 wallet/merchant, and not a guaranteed customer or previously verified distinct paid POST order. Buyer provides their own authorization and settled USDC; no sale is recorded from free samples or HTTP402. No owner-funded testing, selfpayment, gas, escrow bond, invented security guarantees or identity claims.


# Optional independent buyer-side payment integration for existing original VM5 CSV POST
An original MIT-licensed Node.js x402 v2 **buyer** implementation is at:
https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/tree/main/buyer-client
Default = quote-only, no key/wallet/signature/gas/payment. Optional real payment is opt-in with a buyer's separately held low-value signer, two independent payment confirmation guards, amount0.005 native Circle BaseUSDC exactly, official paid POST endpoint and existing VM5 payTo pinned. Synthetic local SDK tests exercise 402->signed dummy request->HTTP200 and reject changed price/payee/network/asset before signing. The example did not purchase or cause a settlement for this merchant and must not be interpreted as an existing customer or paid transaction.

## Free private CSV checker for your own input (no upload or payment)
- https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/csv-free-local-checker.html
- This page runs client-side structural checks with no user data sent and no wallet checkout. Paid reports are a separate, explicitly independently purchased VM5 x402 API for 0.005 native Circle USDC on Base; an HTTP 402 is NOT a sale.

## Original public website QA fixed-price pilot (new independent seller offer, 2026-10-20)
- Buyer-facing published product: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/services/public-web-qa-19-usdc.html
- Price: indicative 19 native Circle USDC on Base for up to five explicitly authorized public HTTPS pages from one origin, after written paid contract/acceptance. Email request is NOT a purchase.
- Real original proof: https://github.com/livastic-vm3-primary-tmp-260920/public-web-qa-smoke-evidence-20261020 (19/19 offline tests; five original owner-controlled demo pages HTTP200). No paid customer order or 3rd-party-client experience asserted.
- Deliverables: bounded read-only HTTP/HTML structural smoke report, reproduction evidence, suggested fixes, one agreed retest. No credentials, payments, production penetration test, human screen reader/WCAG certification, or real phone browser promised.

## Free local HTML structure preflight, buyer-conversion proof (2026-10-20)
- Zero-upload, browser-only source heuristic: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/html-free-local-checker.html
- Only pasted nonconfidential HTML, checks local issues, no URL fetch or form submission or signer or payment; source https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/blob/main/html-local-check.mjs . Original 18 offline tests, transparent limitations, not real site or WCAG certification.
- Distinct paid authorized five-page public-site smoke QA pilot remains 19 native Base Circle USDC quote, no actual buyer contracts claimed.

## Original free x402 quote review tool (2026-10-20)
- URL: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/x402-quote-safety.html
- Never transacts: browser-local JSON or public PAYMENT-REQUIRED x402 v1/v2 header inspection, exact native Circle Base USDC contract / chain / amount/ payTo / expected endpoint comparison. Live example one OPTIONAL unsigned GET of the existing same-one-owner VM5 paid CSV GET merchant (HTTP 402 only). No account, wallet, seed, signature, contract, selfbuy or chain-payment proof. Merchant identity not authenticated by quote text. Original pure JS code and 21 offline tests published on GitHub in the same site repo.
- Full paid customer-input CSV POST x402 API still costs 0.005 native Base Circle USDC per buyer-authorized call; original VM5 merchant only. Original paid API route does not have an externally verified PAID POST customer. One beneficial owner VM1/VM2/VM3/VM5.

## Free Base USDC seller receipt ledger (local-only, 2026-10-20)
Buyer URL: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/base-usdc-merchant-ledger.html
Source module: https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/blob/main/usdc-ledger-local.mjs
No account, wallet connection, browser storage, payment or file upload. The free browser checks user-supplied event CSV against canonical Base 8453 and Circle USDC token contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913; flags duplicate chain:txHash:logIndex, conflicting rows, wrong recipient or asset, incomplete delivery; exports local exception review. Exact row cap 500 and bytes cap 32768. Nothing about the CSV proves an on-chain settlement, receipt, tax event or merchant's actual cash revenue.
Optional zero-network JSON helper: https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/blob/main/usdc-receipt-json-local.mjs decodes ONLY user-pasted raw eth_getTransactionReceipt JSON (100 KiB max) into transfer-log CSV. Requires a successful claimed receipt and logIndex. Does not authenticate chain/network, block inclusion or payment; output delivery_status is ALWAYS unknown until independently reviewed. Original full unit/browser tests guard this boundary.
Optional separate buyer-accepted manual public-chain evidence memo is 5 native Base USDC for one receipt or 15 USDC for five, following a written scope, payment recipient and acceptance criteria: https://opentask.ai/profiles/cmvckd5ok00cx08jyc1yh8bvz ; direct quote mailto:onecursor1@gmail.com. That public profile is not an instant checkout; no customer purchase or payout claimed.

## NEW optional Base USDC browser buyer checkout beta (2026-10-20)
- Real public browser URL: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/csv-browser-x402-checkout.html
- This is an optional BUYER-controlled UI for the EXISTING same-one-owner original VM5 POST https://vm5-openapi-x402.onrender.com/v1/csv-preflight; it does not charge automatically. Quote preview sends the customer-authorized non-confidential CSV to VM5 without payment. If they separately choose to pay, an independently funded injected EIP-1193 wallet must explicitly accept one 0.005 native Circle Base USDC exact EIP-3009 transfer authorization after pinned-chain, token, payee, amount and resource verification. Browser still in initial BETA; NO independently verified customer-funded paid use of browser checkout has been demonstrated. NEVER paste wallet private keys, client confidential CSV or sign arbitrary typed data. This site does not custody or sign as the merchant.
- Original browser buyer source, esbuild reproducible dependency lock, tests: https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/tree/main/browser-buyer . VM5 hosted API remains sole merchant; one human economic owner.

## NEW original privacy-first crypto wallet/exchange CSV pair preflight (2026-10-20)
- Public free preview: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/crypto-transfer-csv-pair-auditor.html
- Original reusable offline engine: https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/blob/main/transfer-pair-local.mjs ; tests https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/blob/main/tests/transfer-pair-local.test.mjs .
- User-provided outgoing vs incoming authorized CSV, exact asset/amount/ref match and time-offset heuristics, duplicate/no-match/ambiguous review, row-only JSON export. No network, analytics, wallet, transaction-signing, tax computation, cost-basis advice or claimed onchain settlement. A candidate transfer is NOT confirmed user-owned or tax free.
- Optional feedback mailto collects only the voluntarily supplied sender email + short anonymized note; no actual user respondents or sales claimed. Indicative 15 native Base USDC for up to 5 separately commissioned, redacted, source-linked discrepancy memo cases AFTER legally agreed independent buyer scope, payee and payment; not an online checkout. This is distinct from original VM5 0.005 native Base USDC x402 generic CSV structural preflight, which does not match cross-account transfers.

## Firstparty Kraken Ledger CSV source compatibility addendum (October 20 2026)
- Transfer pair free tool https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/crypto-transfer-csv-pair-auditor.html now explicitly recognizes official Kraken ledger headers txid/refid/time/type/subtype/aclass/asset/amount/fee/balance, UTC time, negative withdraw/positive deposit. Internal exchange txid NEVER an onchain hash, skip trades/staking, display excluded-row counts; no tax, ownership or chain verification. Firstparty source https://support.kraken.com/hc/articles/360001169383-how-to-interpret-ledger-history-fields . Original synthetic samples/test cases, no private Kraken user files.

## ORIGINAL VM3 free x402 browser CORS doctor (2026-10-20)
Public browser link: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/x402-browser-cors-doctor.html
Original pure local source: https://github.com/livastic-vm3-primary-tmp-260920/defi-payment-proof-qa/blob/main/x402-cors-doctor-local.mjs
Built for documented x402 HTTP 402 CORS browser-readability/preflight issues (x402 Foundation issue #3722). One buyer-authorized public GET (no payment header/signature/credentials/wallet; no auto requests) checks whether an actual browser sees unpaid HTTP402's PAYMENT-REQUIRED. Offline user-pasted 402 and OPTIONS HTTP header transcripts are parsed locally to identify missing Access-Control-Allow-Origin, Access-Control-Expose-Headers for PAYMENT-REQUIRED/PAYMENT-RESPONSE, bad OPTIONS code or absent PAYMENT-SIGNATURE/Content-Type allow lists; no transcript means unknown, never a positive payment claim. Field reference from original same-beneficial-owner public VM5 0.005 USDC x402 merchant is a correctly readable 402/OPTIONS204 only, not a transaction or paid buyer. No contract, quote acceptance, wallet settlement or money claimed.
Optional separate human client asks for a scoped CORS/402 report using the original single-owner email mailto:onecursor1@gmail.com; existing Soul.Markets 0.75/1.50 USDC schemas analyze unsigned public quote shapes but do not test browser CORS or signed delivery. Real buyer feedback survey: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/base-usdc-merchant-ledger.html#buyer-feedback . No automatic mass outreach, tracking or signer.

## Original VM3 paid 1.50 Base USDC x402 browser CORS remediation blueprint (2026-10-20)
Buyer-facing scope and safety: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/services/x402-cors-remedy-150-usdc.html
Official public marketplace profile with 5 real service listings: https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa
New specific paid SKU x402-browser-cors-remedy. Agent POST https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa/services/x402-browser-cors-remedy/execute . Required input server_framework, browser_origin, intended_method and public_402_headers; optional public_options_headers and observed_browser_symptom. All user-provided PUBLIC sanitized unsigned response headers. No private keys, bearer values, signed PAYMENT-SIGNATURE or client customer records.
Official buyer instructions https://docs.soul.mds.markets/guides/buying: the buyer MUST include their OWN public EVM address as X-Agent-ID to get the real service quote. Confirmed unsigned native Base Circle USDC HTTP402 price 1.500000, quote_id provided; platform split service 1.50, fee0.30, hypothetical seller share1.20 IF customer pays and job completed. Without X-Agent-ID, generic platform quote 0.001000 is NOT this SKU price. No paid buyers, jobs, USDC settled receipts, or withdrawable income from this action.
Paid work is AI-assisted offline framework CORS remediation examples; not a live merchant test, security audit, onchain settlement check or real signed x402 paid retry. FREE independently useful original Browser CORS Doctor https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/x402-browser-cors-doctor.html . Optional human-authored fixed 15 Base USDC scoped work requires buyer agreement separately.
