Pay-per-call stock data for META via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for META (Facebook/Meta Platforms) through an x402-gated API. Each call costs $0.02 in USDC on the Base network — the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys or accounts are required; payment is handled inline via the x402 protocol's X-PAYMENT header.
The provider hosts a broader suite of endpoints spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation), all priced uniformly at $0.02 per request. However, this specific listing covers only the `/api/v1/stocks/META` endpoint. The endpoint accepts POST requests and returns JSON.
Documentation 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 example request/response payloads, and no description of the response format beyond the MIME type `application/json`. The endpoint is confirmed live via a valid 402 challenge response.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request parameters, no example responses, and all documentation pages are empty beyond a wallet-connect prompt. The actual data returned by the stocks/META endpoint is entirely unknown.
