What it does

This endpoint at lowpaymentfee.com provides token-level data for BLUR (and likely other tokens at similar paths) behind an x402 paywall on the Base network. Each request costs $0.02 in USDC, settled on-chain with no API keys, rate limits, or subscriptions required.

The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services — all at the same $0.02/request price point. The specific `/api/v1/tokens/BLUR` path falls under the Finance & Web3 category and likely returns token quote or market data for the BLUR token.

Documentation is extremely sparse: the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawl. The x402 challenge confirms the endpoint is live and accepting POST requests, paying to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` in USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maxAmountRequired of 20000 base units (6 decimals) equals $0.02.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual data returned is entirely unknown, making this effectively a stub listing.

Warnings

  • —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
  • —No OpenAPI or output schema provided; response format is unknown
  • —No request body schema documented; unclear what parameters (if any) the POST accepts
  • —The specific data returned for /api/v1/tokens/BLUR is not described anywhere in the crawl
