Pay-per-call stock quote for INTC (Intel) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for Intel Corporation (ticker: INTC) through an x402-gated API. Each request costs $0.02 in USDC on the Base network — no API keys, no subscriptions, and no rate limits. The caller sends a POST request with an X-PAYMENT header containing a valid x402 payment proof, and the endpoint returns JSON stock data.
The provider, lowpaymentfee.com, hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/stocks/INTC` falls under the finance category and is described simply as "Premium API Access." No detailed documentation, request/response schemas, or example payloads are published — the docs, pricing, and README pages all resolve to a minimal "Connect wallet" prompt.
Because no OpenAPI spec, request body schema, or sample response is available, the exact fields returned (e.g., current price, volume, OHLC, market cap) are unknown. Agents should expect a JSON response but must discover the payload structure empirically. The endpoint is confirmed live: it returns a well-formed x402 challenge (HTTP 402) with version 1, scheme "exact", asset USDC (0x8335…), and a maxAmountRequired of 20000 base units (i.e., $0.02 given USDC's 6 decimals).

Quality
The endpoint is confirmed live with a valid x402 challenge and clear pricing ($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 stubs. The actual data returned is entirely unknown, making this effectively a stub listing.
