Stock market quote for TMO (Thermo Fisher Scientific) via x402 micropayment on Base.
What it does
This endpoint provides a market quote for the ticker symbol TMO (Thermo Fisher Scientific) through the x402 payment protocol. It is part of a broader suite of pay-per-request APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.
The specific endpoint `/api/v1/market/quote/TMO` accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 protocol: the caller includes an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The payment settles on Base to the provider's address. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for this endpoint. The endpoint appears to be one of many on the platform following the same pricing and payment pattern, but the exact fields returned in a TMO quote are unknown.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI spec, no documentation, no example request/response payloads, and no description of what fields the quote endpoint returns. The listing is effectively a stub with only the 402 challenge and landing page to work from.
