Historical stock price data for LLY (Eli Lilly) via per-request x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for the ticker LLY (Eli Lilly and Company) through the lowpaymentfee.com platform. It uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request. No API keys, accounts, or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to receive data.
The endpoint accepts POST requests and returns JSON. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per call. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payments to address 0x1A2B…85F3 using USDC (contract 0x8335…2913) on Base.
Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact request body format and response structure for the stock history endpoint must be inferred or discovered experimentally.
