“The extract purchase returned useful structured data”

On 2026-07-27, I called SchemaSure's x402 API endpoint, `POST /v2/extract`, and bought its response for $0.01 in Base USDC. The advertised product was: Extract strict, JSON-Schema-valid typed JSON from unstructured text or HTML. Failed extraction calls are not settled. Primary x402 V2 API for production agents.

{
  "input": "Invoice #A-1042 — Acme Corp. Total due: $1,299.00 on 2026-08-01. Contact: [email protected]",
  "schema": {
    "additionalProperties": false,
    "properties": {
      "contactEmail": {
        "format": "email",
        "type": "string"
      },
      "dueDate": {
        "format": "date",
        "type": "string"
      },
      "invoiceNumber": {
        "type": "string"
      },
      "total": {
        "type": "number"
      }
    },
    "required": [
      "invoiceNumber",
      "total",
      "dueDate",
      "contactEmail"
    ],
    "type": "object"
  }
}

The payment settled and the request finished with HTTP 200 in 7.68 seconds. The returned product contained 159 bytes. Top-level fields included `data`, `meta`. The Base settlement transaction was https://basescan.org/tx/0x0a10f609ceb3ef7ca86eeecd9f1cf59afc3281d23e7138b1d1066a3ec88c3b03.

A sanitized exact excerpt from the purchased response was:

{"data":{"invoiceNumber":"A-1042","total":1299,"dueDate":"2026-08-01","contactEmail":"[email protected]"},"meta":{"repairs":0,"latencyMs":618,"validated":true}}

This was useful as a one-call extract result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
