What it does

This x402-enabled endpoint at lowpaymentfee.com provides a "Premium API Access" receipt resource for transaction ID 202. It is part of a broader platform offering multiple pay-per-call API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.

The specific endpoint `/api/v1/transactions/202/receipt` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 "exact" scheme. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The payment timeout is 300 seconds.

The broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation — all at the same $0.02 price point. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages only show a "Connect wallet" prompt), so the actual behavior and response schemas of these endpoints are unverified.

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation beyond a landing page, and the specific purpose of a 'transaction 202 receipt' is unexplained. The docs, pricing, API, and README pages all render only a 'Connect wallet' prompt with no substantive content.

Warnings

  • —No documentation available — all doc pages render only 'Connect wallet' with no content
  • —No response schema or example responses provided for any endpoint
  • —The specific meaning of 'transactions/202/receipt' is unclear — it may be a demo or placeholder resource
  • —The platform advertises many endpoint categories (AI, finance, etc.) but none are verified beyond the landing page listing
