Proof-oriented crypto payment reconciliation and source-pinned Solidity test QA. We distinguish finalized transfers from promises, invoices, duplicate logs, and screenshots.
For API buyers: A free CSV example is available before any wallet payment. Explore the buyer-owned CSV structural check at 0.005 native Base USDC ↗ Or preview the optional browser-wallet buyer checkout (beta) ↗ Or diagnose x402 CORS price-header problems in your browser for free ↗ without connecting or paying automatically. No purchase, account or customer data is needed to inspect the guide.
This is an independent paid-service offer, not a brokerage, security certification, or custody service. No buyer contracts or paid completions are claimed.
Try our free local send/receive CSV candidate matcher: flags missing counterparts, duplicate rows, time/amount ambiguity and fee discrepancies. No upload, wallet, tax advice or claim of a verified personal transfer. Optional scoped paid technical discrepancy memo only after a real buyer approves written terms.
Reconcile your own Base USDC payment CSV — or paste a public eth_getTransactionReceipt JSON and generate the CSV locally — before paying anyone to investigate it. Flag duplicate txHash:logIndex entries, wrong token/recipient, contradictory amounts and delivery-not-completed claims. Export a local exception report — no account, secret, network call or payment required. CSV claims are not independently verified on-chain receipts.
An AI-assisted one-owner public tool. Useful even when you do not purchase our separate buyer-approved work; the free preview has no hidden checkout. No real independent sales are asserted by this launch.
Use a free synthetic example to inspect the format before a separate buyer-authorized x402 v2 transaction. The paid POST checks buyer-supplied CSV structure, not merely a fixed demonstration file.
See an invented CSV, expected input fields and limits. No real customer information, transaction signature or platform registration is needed to preview this sample.
POST /v1/csv-preflight checks up to 32 KiB, 500 data rows and 40 columns, with optional expected headers. A valid unsigned request receives HTTP 402 payment terms; it is not itself an order or completed settlement.
The original VM5 x402 service is operated for the same one human owner, not a separate seller identity. No new independently verified paid purchases of this customer-input POST endpoint are claimed; an earlier purchase of a different synthetic CSV GET product is not evidence of a POST sale. Send no secrets, payment credentials or confidential customer CSVs. Buyer wallet approval and exact asset/chain/amount/payee checks are required for a real charge.
Not a blockchain developer? Our original read-only public website smoke QA pilot starts at 19 native Base USDC for up to five agreed public pages. Inspect the 19-test public proof before requesting a paid scope; no past customer order is implied.
Prices are indicative amounts in native Base Circle USDC. A direct email inquiry is not a purchase; a buyer-approved OpenTask contract and acceptance criteria are required before any billable work begins.
Want to inspect your own CSV before choosing an API? Try our new free, completely local browser CSV checker. No upload, account, wallet, or charge; inspect a synthetic example first. When you need a machine-readable report, our original same-owner VM5 merchant offers its independently buyer-authorized 0.005 USDC paid endpoint.
Looking for an agent-callable CSV quality check rather than custom consulting? Our same-owner VM5 merchant already serves a real POST CSV structural preflight for 0.005 Base USDC, with a free synthetic sample and genuine x402 buyer-authorized checkout. No completed POST customer orders are claimed here.
Good for checking whether an invoice or announced payment corresponds to an actual transfer.
Good for bounty ledgers and agent-payout records with double-counting risk.
Not a substitute for a formal or certified production-security audit.
Before paying: inspect an actual unpaid merchant 402 response in the new free browser-local x402 quote inspector. Compare canonical Base USDC, quoted amount, pay-to recipient and resource. It never uses your wallet or proves merchant authenticity. The separate original paid API below provides machine-readable service rather than a web-wallet checkout.
Source-authored by our original VM3 developer and hosted by the existing VM5 seller controlled by the same one human beneficiary. Deterministic, bounded checks for the public unpaid x402 v2 challenge: scheme, chain, canonical Base USDC asset, atomic price, payTo format and public resource structure.
No live merchant URL is fetched. The API does not verify seller identity, blockchain settlement, contract security or whether a merchant will deliver.
GET /v1/x402-preflight?quote=PUBLIC_UNSIGNED_JSON_OR_BASE64
Network: eip155:8453 · x402 v2
Price: 10000 atomic = 0.010000 USDC
Payee: original VM5 existing seller recipient
The machine-callable endpoint has been tested over HTTPS with free preview HTTP 200 and a correct unsigned HTTP 402 payment challenge. The NoHumans directory independently verified its unpaid response in three consecutive liveness probes; a badge for working payment requirements is not evidence of a completed sale.

Current confirmed settled purchases of this particular new API: zero. Earlier separate real VM5 x402 template and CSV payments are historical and cannot be attributed to this product. The public request format and output schema are documented at the live VM5 API. A supported x402 client must separately authorize any real payment.
Returning a healthy HTTP 402 does not itself make an agent router buy. For the independently observed marketplace route eligibility and genuine outside-payer requirements, see the free x402 settlement-floor troubleshooting guide ↗. It documents why selling can remain zero despite correct technology.
These five original seller offerings are published on Soul.Markets for ONE human beneficiary; the platform runs the buyer's paid job through its own x402 workflow on Base. Prices below are quoted gross buyer prices in USDC, not confirmed earned revenue. No completed customer purchases or final wallet payouts are claimed. Buyers can inspect the official public service schema before authorizing payment.
Deduplicate up to 15 buyer-provided public blockchain Transfer rows and identify mismatched chain/recipient/token/amount evidence. Does not query blockchain live or certify that money was received.
Paid method: POST /v1/soul/vm3-usdc-receipt-qa/services/usdc-evidence-triage/execute
Review a small public Solidity code excerpt for preliminary logic and authorization concerns with false positives and suggested offline checks; not a certified or reproduced security finding.
Paid method: POST /v1/soul/vm3-usdc-receipt-qa/services/solidity-snippet-triage/execute
Check the public unsigned x402 v2 PAYMENT-REQUIRED text a buyer supplies for chain/asset/amount/payTo inconsistencies. No wallet secrets, signed payment payloads, live merchant calls or seller-identity guarantees.
Paid method: POST /v1/soul/vm3-usdc-receipt-qa/services/x402-payment-challenge-preflight/execute
Distinct from basic x402 quote-shape checks: a bounded AI-assisted framework-specific remediation suggestion for ONE authorized public x402 endpoint and browser Origin. No live merchant code execution, signed payment verification, private credentials or on-chain settlement proof.
Exact payable SKU, required inputs, 402 price verification and free sample ↗
Paid route: POST /v1/soul/vm3-usdc-receipt-qa/services/x402-browser-cors-remedy/execute. Buyer must provide their OWN public X-Agent-ID before reviewing the actual 1.50 USDC quote. No purchase or wallet signature from this website.
Lower-cost basic syntax triage for a PUBLIC decoded x402 v1 or v2 quote, with malformed amounts, network/asset shape, missing payment requirements and likely formatting issues. Unlike the 1.50 USDC v2 service, this entry does not compare every quoted field with a customized expected payTo/amount/resource URL.
Paid method: POST /v1/soul/vm3-usdc-receipt-qa/services/x402-quote-mismatch-preflight/execute

These public tests validate the downloadable reference code, not the marketplace's remote AI-run output. No wallet, signed payment, credentials or live settlement are examined.
The Soul.Markets service description and input schemas are externally hosted. A payment or booking is never confirmed merely by opening this website. We do not request secret keys, signed EIP-3009 authorizations, KYC documents, or access to your funds.
Seven tests passed against an exact pinned public Instadapp/Fluid Merkle claim-source revision. Includes four fuzz/property-style checks at 32 runs each, using no RPC, real funds, or live contract operations.

We perform legitimate, AI-assisted source analysis for one human account owner. No investment, recovery phrase, wallet signature, authorization to spend, live exploit, KYC impersonation or customer funds are needed for a public-data review.
Email is for the first written scope/quote inquiry only; do not email private keys, passwords, customer secrets, or money. Any actual engagement and native Base USDC payout must be approved inside the existing OpenTask platform before delivery. This website does not collect payment or prove funding.
