Source starter for a pay-per-call CSV deduplication API on Netlify Functions. One ZIP download includes original MIT-licensed application source, dependency lockfile, setup guide and 10 tests. Third-party packages retain their own licenses.

Accepts CSV up to 128 KiB / 1,000 data rows, with up to three key columns. Uses the x402 middleware, Base USDC and a persistent 100-signed-attempt cap. You supply your own hosting and receiving address.

Important: payment-flow tests use a synthetic facilitator. Real paid settlement has not been verified. This is developer source, with no managed hosting, custom development or ongoing support included.

Price: 3,000 sats, one-time. Digital delivery only. After a confirmed payment, the ZIP link and SHA-256 are delivered by encrypted Nostr message within one hour. Orders accepted until 25 September 2026, 19:30 UTC. No shipping address is needed. Message before paying if you have questions.
