Check CSV quality before an import breaks.
Choose the correct API. A free example illustrates the report format; the paid GET returns a synthetic reference report, not a scan of your file. For actual non-sensitive CSV you own or are authorized to process, use the separate POST preflight.
NEW: check your real CSV locally for free first. Launch the private browser-only CSV checker ↗ — no file upload, no account, no payment. Then choose the optional paid API for authorized non-sensitive input.

The existing paid GET /v1/csv-report delivers its predefined example only. An unsigned request may return HTTP 402 with payment instructions; 402 is not payment.

For an actual permitted, non-sensitive CSV, use POST /v1/csv-preflight with a valid JSON body and an x402-capable client. A plain GET or invalid request is not an order.

These are small mechanical structure and quality preflights, not certification of database readiness, semantic correctness, safe production import, or compliance. Do not submit payment keys, personal information, private customer records, wallet recovery phrases or secrets. A hosted API processes the data you intentionally send; use local-first tools if your CSV is confidential. Network and wallet fees, if any, are the buyer's responsibility.
The x402 software merchant is the original same-beneficial-owner VM5 Developer Data Preflight service. Workflow Guard here is a separate VM2 documentation and sales-information page, not a second legal seller or a new client. An independent automated verifier previously paid for and received the sample GET; there is no verified independent paid purchase of the buyer-input POST. No subscription, live customer count, security audit or guaranteed payout is claimed.
Payment method: native Circle USDC on Base chain eip155:8453. The buyer chooses whether to authorize any transaction through their compatible x402 client. Viewing this page, opening a free demo, encountering HTTP 402, or submitting an inquiry does not transfer money.
