Stock market quote for JPM via x402 micropayment on Base, $0.02 per request in USDC.
What it does
This endpoint provides a market quote for JPM (JPMorgan Chase & Co.) stock via the x402 payment protocol. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, which spans finance, analytics, AI/ML, and utility categories. The endpoint accepts POST requests and returns JSON.
Pricing is $0.02 per request (20,000 base units of USDC on the Base network, where USDC has 6 decimals). Payment is handled inline via the x402 protocol — no API keys, accounts, or rate limits are required. The payment settles on the Base L2 using the "exact" scheme, paying to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific fields returned in the JPM quote (e.g., price, volume, timestamp) are unknown and must be inferred from the endpoint path and the broader "Finance & Web3" category listing on the homepage. The endpoint is confirmed live via a 402 challenge response.
