Pay-per-call stock quote for PEP (PepsiCo) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com returns stock data for PepsiCo (ticker: PEP) behind an x402 paywall. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.
The specific endpoint `/api/v1/stocks/PEP` accepts HTTP POST requests and returns JSON. The x402 challenge was successfully captured, confirming the endpoint is live. Payment is settled on-chain using USDC (contract 0x8335…2913) on Base with the "exact" scheme at a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The payment timeout is 300 seconds.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint's actual data source and field coverage for stock quotes are unknown. Prospective users should test with a small payment to verify the response format meets their needs.
