What it does

This endpoint at lowpaymentfee.com provides a market quote for the MCD token (likely MakerDAO's MCD or a related asset). It is part of a broader platform offering dozens of pay-per-request APIs spanning finance, AI/ML, data analytics, and infrastructure utilities — all gated via the x402 payment protocol on the Base network.

The endpoint accepts HTTP POST requests and returns JSON. Payment is settled in USDC (contract 0x8335…2913 on Base) using 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). There are no API keys, no rate limits, and no subscription commitments — each request is individually paid at the time of the call. The payment timeout is 300 seconds.

Documentation on the site is extremely thin: the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the quote response contains. The endpoint is confirmed live (returns a valid 402 x402 challenge), but the lack of documentation means callers must experiment to discover the request body format and response structure.

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 OpenAPI schema, no documented request/response format, no example payloads, and all documentation pages render only a wallet-connect prompt. The listing is essentially a stub with confirmed liveness.

Warnings

  • —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.
  • —No OpenAPI or JSON schema for request or response bodies; callers must reverse-engineer the API.
  • —The specific meaning of 'MCD' (MakerDAO, or another token) is not documented.
  • —No SLA, rate-limit, or uptime guarantees are published.
