What it does

This endpoint returns the current stock price for Amgen (AMGN) through the lowpaymentfee.com platform. It uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per call. No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to receive the data.

The provider, lowpaymentfee.com, offers a broad catalog of pay-per-call APIs spanning finance, AI/ML, data analytics, and utility services, all priced at $0.02 per request. This specific endpoint is part of the Finance & Web3 category and serves stock price data. The response MIME type is application/json. The endpoint accepts POST requests and is marked as discoverable.

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. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation means callers will need to experiment to determine the exact response format.

Quality

0.35/ 1.00

The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no example request/response, and all documentation pages are empty beyond a wallet-connect prompt. The response schema is entirely unknown, making this effectively a stub listing.

Warnings

  • —No OpenAPI or schema documentation available — response format is unknown
  • —All doc/pricing/README pages render only 'Connect wallet' with no content
  • —No example responses available; callers must discover the payload format experimentally
  • —The specific /stocks/AMGN/price endpoint is not listed on the provider's landing page catalog, though similar finance endpoints are
