What it does

This x402-enabled endpoint at lowpaymentfee.com provides a "Premium API Access" receipt resource for transaction ID 94. It is part of a broader platform offering multiple pay-per-request API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.

The specific endpoint `/api/v1/transactions/94/receipt` returns a JSON response upon payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). Payment is made via the x402 protocol's "exact" scheme: callers include an X-PAYMENT header with a signed payment to the designated payTo address. No API keys, rate limits, or upfront commitments are required — access is instant once payment is verified on-chain.

The platform's landing page lists 16 endpoints across four categories, all at the same $0.02 price point. Documentation pages (docs, pricing, README) appear to require a wallet connection and contain no additional readable content. There is no OpenAPI schema, no detailed request/response documentation, and no example payloads available from the crawl. The exact data returned by this particular receipt endpoint is unclear beyond its JSON MIME type.

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a landing page listing, and the specific purpose of this receipt endpoint is vague. Docs pages all require wallet connection with no readable content.

Warnings

  • —No OpenAPI or schema documentation available for this endpoint
  • —Documentation, pricing, and README pages require wallet connection and have no readable content
  • —The specific data returned by the /transactions/94/receipt endpoint is undocumented
  • —Purpose of 'transaction 94' receipt is unclear — may be a demo or placeholder resource
