Market quote for MCO token via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the MCO token (likely referring to MCO/MODUM or a similar crypto asset). It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint `/api/v1/market/quote/MCO` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, requiring a maximum payment of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). The platform advertises no API keys, no rate limits, and instant access — you simply attach an x402 payment header to each request.
Documentation beyond the landing page is extremely sparse; the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what fields the MCO quote returns. The endpoint likely returns standard market-quote data (price, volume, timestamp, etc.), but this is inferred from the path naming convention rather than documented.

Quality
The x402 challenge confirms the endpoint is live with clear pricing ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, and all documentation pages are empty stubs. The actual data returned by the MCO quote endpoint is entirely unknown.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or JSON schema describing request parameters or response fields.
- —The meaning of 'MCO' in this context is not documented; it could refer to multiple tokens.
