Market quote endpoint for MO, paid per-request via x402 on Base with USDC.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the asset or symbol "MO" via a POST request. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, spanning data analytics, AI/ML inference, finance, crypto, 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/MO` costs up to $0.02 per request (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The endpoint returns JSON and accepts POST requests.
Documentation on the site 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 schema, no request/response examples, and no description of what fields the quote response contains or what request body parameters are expected. The "MO" in the URL path likely refers to a ticker symbol (e.g., Altria Group Inc. on NYSE), but this is not confirmed by any documentation. The platform advertises simple pricing at $0.02/request across all endpoints, no minimums, and no commitments.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payments. However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The purpose of the endpoint (what 'MO' refers to, what the response contains, what POST body is expected) must be inferred entirely from the URL path. This is effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.
- —No request body schema or response schema documented; callers must guess at the expected input and output format.
- —The meaning of 'MO' in the URL path is not documented — it is assumed to be a market ticker symbol but this is unconfirmed.
- —No OpenAPI or ai-plugin manifest found.
