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.\n\nThe 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.\n\nDocumentation 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.","tags":[],"capabilities":["stock-quote","pay-per-request","x402-payment","usdc-settlement","base-network","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price API","PEP stock data","PepsiCo quote","equity data endpoint","x402 stock API","pay-per-call finance","USDC micropayment API"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc/pricing/README pages render only 'Connect wallet' with no content","No example responses; actual stock data fields, freshness, and source are unverified","The endpoint path is ticker-specific (/stocks/PEP); coverage of other tickers is unconfirmed"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/PEP","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/stocks/PEP","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
