What it does

This endpoint at lowpaymentfee.com provides access to a transaction receipt (resource ID 292) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals).

The broader lowpaymentfee.com platform advertises a suite of x402-gated APIs spanning data & analytics (metrics, reports, data export, insights), AI & ML (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no commitments required.

However, the specific endpoint being listed here — `/api/v1/transactions/292/receipt` — is not documented among the advertised API categories on the landing page. Its purpose appears to be retrieving a receipt for a specific transaction (ID 292). No request body schema, response schema, or detailed documentation is available for this endpoint. The docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.
