What it does

This endpoint at lowpaymentfee.com provides a transaction receipt resource at `/api/v1/transactions/371/receipt`. It is part of a broader platform that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all settled via the x402 protocol on the Base network using USDC.

The specific endpoint probed returns a 402 challenge requesting payment of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per call. Payment is made via the x402 "exact" scheme to a designated wallet address. The platform advertises a flat $0.02 per request across all endpoints, with no API keys, no rate limits, and instant access.

Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the transaction receipt endpoint actually returns. The endpoint is live (402 challenge confirmed), but the lack of documentation makes it difficult to determine the exact payload format or use case for this specific resource. The broader site lists many endpoint categories but provides no further technical detail beyond names and prices.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 402 challenge, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the receipt resource contains. The site's docs/pricing/API pages are all blank beyond a wallet connect prompt. This is effectively a stub listing.

Warnings

  • —No OpenAPI schema or endpoint documentation available
  • —Docs, pricing, API, and README pages all render only 'Connect wallet' with no content
  • —No request or response examples available — payload format is unknown
  • —The specific resource '/api/v1/transactions/371/receipt' is hardcoded to transaction ID 371; unclear if other IDs are supported or how to discover them
