Open-source tests · One real economic owner · Explicit USDC terms
Free, privacy-conscious CSV checks for wallet transfers and USDC workflows. Two separate, one-owner proposed 49-USDC written-scope pilots target (1) crypto CSV missing acquisition and transfer pair errors, and (2) merchant Base USDC invoice matching. These are price hypotheses, not proven paid sales. Explore reproducible demos first. If you need automated hosted CSV structure QA, our existing vendor offers a separately authorized 0.005 native Base USDC x402 request.
No wallet connection for free tools. No spreadsheet upload to this landing page. No tax filing or promise of final blockchain settlement. Real paid merchant functionality is distinct from free local previews.
1st market to validate · Crypto CSV Rescue · Proposed 49 native Base USDC one-off pilot · No automatic charge
For an independent user or their authorized tax professional, duplicate imports, missing exchange-to-wallet transfer counterparts, wrong time zone, contract/fee differences or unavailable older acquisition rows can distort reported records. The proposed human-reviewed report covers one narrowly defined issue cluster, at most 50 safely redacted rows and two original exports. It never creates a missing purchase, tax cost basis, tax return, transaction proof or unsupported self-transfer assumption.

Before spending: this is a proposed market test with no independently verified paid buyers. Try the original free private local transfer-pair checker. No customer CSV upload on this page, wallet signing, tax practice, professional attestation, instant quote checkout or claimed customer result. Any paid job requires explicit written scope, source-data authorization, privacy handling and agreed BaseUSDC recipient first.
Merchant pain before product proliferation · Proposed 49 native Base USDC pilot · No instant payment
For a genuine independent crypto merchant, a bounded up to 50 authorized invoice rows and 50 candidate Base USDC Transfer events may reveal unmatched records, underpayments, repeated CSV imports, wrong chains/tokens and invoices needing manual attribution. The proposed 49-USDC single report is an unvalidated pricing hypothesis, not accepted paid work or a working automated invoice-matching backend.

Alternative: inspect existing FIXED 19-USDC synthetic-only mini review (0 orders so far) ↗
No client invoice or customer data is collected by this static page. We use entirely invented example transaction references; no fake explorer hashes or testimonials. First ask for a written scope, security/permission agreement, acceptance and payment/refund terms. No wallet signing, invoice upload or actual merchant receipt is required to browse.
Use the existing local-only free Base USDC ledger inspector first ↗
No upload · Wallet & exchange
Compare withdrawal and receipt CSVs. Flags duplicate source rows, candidate matches, wrong token, unmatched counterparts and ambiguous same-amount transfers. Includes a Kraken Ledger 12-column invented sample. A candidate match is never proof of a non-taxable self-transfer.
Compare two CSVs locally ↗Unsigned HTTP 402 · Walletless preview
Inspect canonical Base network and Circle native USDC, 6-decimal price, pay-to recipient and resource URL. Compare your own maximum spend, then decide independently. This cannot authenticate a merchant or guarantee execution.
Inspect a payment quote ↗Local only · Base USDC CSV
Review your own transaction-record CSV for repeated rows, mismatched token contracts, and unconfirmed record claims. It does not itself fetch or finalize a blockchain receipt.
Review CSV ledger ↗Local only · General CSV
Catch malformed headers, missing columns, duplicate identifiers and spreadsheet-formula patterns in a local free CSV preflight. Keep your input in your browser.
Inspect CSV locally ↗Public HTTPS · x402 browser integration
Our no-spend Node.js CLI checks real OPTIONS and HTTP 402 headers for missing CORS exposure, allowed payment signature headers, and cache hazards on endpoints you operate. No wallet or token transfer. Free diagnostics support a separately agreed paid CORS remediation service.
Download free x402 smoke test ↗One original live merchant · Optional real x402 purchase
The original same-owner VM5 merchant exposes POST /v1/csv-preflight. It returns a public unsigned HTTP 402 challenge and, following an independent buyer-authorized x402 payment, is intended to return a machine-readable CSV structural report. It is not a tax importer or transfer matching service.
Price quote: 5,000 atomic native Circle Base USDC units (0.005 USDC), one buyer-approved request. Buyer approval and legal service terms are separate from free tools.
The optional browser wallet checkout is an initial beta. A real outside funded browser purchase and independently finalized settlement have not been verified end-to-end. It never auto-signs and requires the buyer's own Base wallet, explicit review and confirmation. Never paste private keys, tax records or confidential CSV into a public service.
Real buyer-authorized x402 marketplace offer · Optional, no automatic payment
Free checks help identify unreadable HTTP 402 PAYMENT-REQUIRED headers and missing OPTIONS permissions. For one merchant-authorized public endpoint and browser Origin, our original VM3 Soul.Markets service sells a 1.50 USDC AI-assisted offline remediation blueprint from sanitized public 402/OPTIONS headers and a selected framework. This is a distinct service from VM5's 0.005 USDC generic CSV checker.
Review exact 1.50-USDC offer, scope and buying guide ↗
Request a separately agreed 15-USDC one-endpoint custom QA pilot ↗
The optional $15 manual pilot requires written scope acceptance before USDC payment; no wallet connection, automatic transfer, live server change, or promised customer revenue. Buyer correspondence goes only to the existing original one-owner contact channel.
Actual Soul.Markets seller name and five real active services can be inspected through its public API. The buyer must use their OWN public X-Agent-ID when requesting a quote: we verified native Base Circle USDC 1.500000, marketplace fee 0.30 and a conditional seller share of 1.20 USDC. No private keys are required to inspect the listing. Platform checkout is separate.
Do not confuse a quote with earned revenue. No independently verified customer has paid for this new SKU and no VM3 earnings have been withdrawn. An unsigned x402 quote is not delivery, settled money or a successful signed retry. If you are not buying, the browser doctor remains fully free.
Diagnose the unpaid 402 in your own browser for free ↗
The real third-party PQS CORS problem is documented publicly in this original issue. It is a noncontracted technical finding, not a customer review or paid project. A separate 15-USDC human-reviewed scope needs written acceptance.
One real owner · One managed customer enquiry queue · No wallet access
To ask about either separate nonbinding 49 native Base-USDC scope, the same owner's VM5 coordinates incoming human project requests. Its existing third-party Google inquiry form asks for a reply email, broad problem/acceptance criteria, optional budget and timing. No Google login is required to view the public form. Google processes browser and response data. This is not a paid order, escrow, merchant-account login or permission to share private financial records. Begin your description with the exact offer name: Crypto CSV Rescue or USDC Invoice Match.
Ask for a written pilot scope — no payment or upload ↗
Use only general, nonidentifying facts. No user CSV, tax documents, account or wallet addresses, invoice/customer details, transaction hashes, secrets or signatures via this form. Actual work may require a separate mutually accepted secure customer-data transfer, service scope, cancellation/refund and BaseUSDC recipient agreement; it is never automatic. Direct email onecursor1@gmail.com remains a separate optional contact.
Actual demand, not invented testimonials
Share only an invented or anonymized example of a recurring wallet/exchange import issue, the rough hours lost, and the actual price you would consider—including $0. One-owner research uses this to prioritize reproducible checks. No wallet signature, invoice, payment or email is required to use the tools.
Give x402 browser-payment feedback in 60 seconds (no login) ↗
This voluntary Google Form asks your actual issue and nonbinding willingness to pay 0 / 1.50 / 15 USDC. It does not require a Google login or auto-collect email. Google processes browser request data and form responses; optional contact is a separate explicit choice. The owner sees submitted answers. Do not submit private merchant/customer data, signatures, wallet seed phrases or confidential endpoint URLs. No payment occurs.
See public developer feedback thread ↗ Send optional anonymous-example feedback ↗
GitHub feedback needs your own GitHub account and is public; email exposes your sender address. Do not send transaction hashes, wallet addresses, account data, personal tax records, private keys, passwords or customer information.
