What it does

This endpoint returns the current stock price for the ticker symbol LIN (Linde plc) through a simple HTTP POST request, paid per call using the x402 protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com covering data analytics, AI/ML inference, finance, crypto, and utility services.

The endpoint accepts x402 payments on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). Each request costs a maximum of $0.02 (20,000 base units with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The response MIME type is application/json.

Documentation beyond the landing page is 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 request/response schema documentation, and no usage examples. The endpoint is confirmed live (returns a proper 402 challenge), but the exact shape of the JSON response is unknown and must be inferred from the endpoint path (likely a JSON object containing the stock price for LIN).

Quality

0.40/ 1.00

The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 per request in USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, and all documentation pages return only a wallet-connect prompt. The response shape is entirely inferred from the URL path.

Warnings

  • —No OpenAPI or schema documentation available — response format is unknown and the example response is speculative
  • —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no technical content
  • —The specific stock endpoint /api/v1/stocks/LIN/price is not listed on the landing page among the advertised APIs, so its availability and data source are unverified
