What it does

This endpoint at lowpaymentfee.com provides a transaction receipt retrieval service accessible via the x402 payment protocol. The specific resource `/api/v1/transactions/364/receipt` returns a JSON receipt when called with a valid x402 payment header. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20000 base units with 6 decimals).

The broader lowpaymentfee.com platform advertises multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities—all priced uniformly at $0.02 per request. The platform emphasizes no API keys, no rate limits, and instant access via wallet-based x402 payments on the Base network. However, documentation pages beyond the landing page returned only a "Connect wallet" prompt with no further technical detail.

The specific endpoint probed here is a transaction receipt resource. Without additional documentation or example responses, the exact schema of the returned receipt is unknown. The endpoint is confirmed live (returns a proper x402 challenge with version 1, scheme "exact", and a 300-second timeout). No OpenAPI spec, robots.txt, or agents.txt were found.

Quality

The endpoint is confirmed live with a valid x402 challenge, but there is no OpenAPI spec, no response schema, no example responses, and documentation pages are empty beyond the landing page. The purpose of this specific receipt endpoint is unclear beyond its name.

Warnings

  • —No OpenAPI or schema documentation available
  • —Documentation pages return only 'Connect wallet' with no technical content
  • —Response format for the receipt is unknown—no example or outputSchema body provided
  • —The endpoint path includes a hardcoded ID (364), suggesting it may be a single-resource demo rather than a general-purpose API
