What it does

This endpoint at lowpaymentfee.com provides BTC token data through an x402-gated API. It is part of a broader platform offering dozens of endpoints across data & analytics, AI & machine learning, finance & Web3, and infrastructure categories — all priced uniformly at $0.02 per request with no API keys, no rate limits, and no commitments required.

The specific endpoint `/api/v1/tokens/BTC` 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 per call. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the payment timeout is 300 seconds.

Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. The exact response schema for the BTC token endpoint is not documented, so the structure of the returned data must be inferred (likely token price, market data, or similar). The endpoint is confirmed live via a valid 402 challenge response.

Quality

0.35/ 1.00

The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation of request parameters, response schema, or example responses. The docs/pricing/API pages are all blank beyond a wallet connect prompt, making this effectively a stub listing.

Warnings

  • —No API documentation available — docs, pricing, and API pages render only 'Connect wallet' with no content
  • —Response schema for /api/v1/tokens/BTC is unknown; no examples provided by the provider
  • —The exact nature of the returned BTC data (price, market cap, historical, etc.) is not documented
