What it does

This endpoint at lowpaymentfee.com provides stock data for the ticker PM (Philip Morris International) through an x402-gated API. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller simply attaches an X-PAYMENT header with a valid x402 payment proof and receives a JSON response.

The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced at $0.02 per request. This specific endpoint (/api/v1/stocks/PM) falls under the finance category. The x402 challenge confirms the endpoint is live, accepts USDC (contract 0x8335…2913) on Base, and pays out to address 0x1A2B…85F3.

Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint accepts POST requests and returns application/json, but the exact fields in the stock data response are unknown.

Quality

0.35/ 1.00

The x402 challenge confirms the endpoint is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty. The actual stock data returned is entirely unknown, making this effectively a stub listing.

Warnings

  • —No OpenAPI or schema documentation available — response format is unknown
  • —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content
  • —No example request or response payloads are available to verify what stock data fields are returned
  • —The endpoint description is generic ('Premium API Access') and does not confirm it returns stock quotes specifically
