Pay-per-call stock quote API for LLY (Eli Lilly) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker LLY (Eli Lilly and Company) through a simple POST request, paid per call using the x402 protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The payment is settled on-chain to a specified wallet address using the "exact" payment scheme.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. The specific /api/v1/stocks/LLY route is not explicitly listed on the homepage but follows the same x402 challenge pattern and pricing as the other endpoints on the platform.
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 actual data source for stock quotes is unknown. Agents should expect a JSON response containing stock information for LLY, but the exact fields and structure must be discovered empirically.
