What it does

Invoice/receipt PNG or JPEG photo OCR to structured JSON for $0.005 USDC on Base, Arbitrum, or Polygon. Send standard padded Base64 as image_base64; maximum 2 MiB and 12 megapixels. Two gpt-6-luna medium-effort calls; quotes are checked against generated OCR text, not image pixels. Review against the original image.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/79617.json for the price and payment options.
3. Pay. Call GET https://agent-evidence-extractor.defcronyke.workers.dev/v1/invoice-image-parse. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, Arbitrum One, Polygon, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
