What it does

This endpoint at lowpaymentfee.com provides a "Premium API Access" receipt resource for transaction ID 70. It is part of a broader platform offering pay-per-request APIs across data/analytics, AI/ML, finance/Web3, and infrastructure categories—all priced at $0.02 per call with no API keys, no rate limits, and no commitments.

The specific endpoint `/api/v1/transactions/70/receipt` accepts POST requests and is gated by the x402 protocol on the Base network. Payment is settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The response MIME type is application/json. The payment timeout is 300 seconds.

Documentation on the site is extremely sparse—most pages beyond the landing page only show a "Connect wallet" prompt. There is no OpenAPI spec, no detailed schema for request/response bodies, and no usage examples. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual functionality behind the receipt resource is not documented.

The endpoint is confirmed live via a valid 402 x402 challenge, but there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page listing, and the specific purpose of 'transactions/70/receipt' is unclear. Effectively a stub listing.

Warnings

  • —No OpenAPI or schema documentation available
  • —All doc/pricing/API pages only render 'Connect wallet' with no useful content
  • —The specific resource path (/transactions/70/receipt) suggests a fixed transaction ID—unclear if this is a demo or production endpoint
  • —No response body schema or example available
