Payment is handled inline using the x402 protocol — each call costs $0.02 in USDC on the Base network, with no API keys, subscriptions, or rate limits required. The endpoint advertises an exact payment scheme, accepting USDC (contract 0x8335…2913) to a specified payTo address, with a 300-second payment timeout.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced uniformly at $0.02 per request. The specific /api/v1/stocks/PNC endpoint is not listed on the provider's landing page catalog (which focuses on analytics, AI, finance, and utility categories), but the x402 challenge is live and well-formed. No OpenAPI schema, response examples, or detailed documentation were found in the crawl; the docs, API, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no substantive content.\n\nBecause no response schema or sample output is available, the exact fields returned by this endpoint are unknown. It is reasonable to infer it returns JSON stock market data for PNC (e.g., price, volume, change), but this cannot be confirmed from the available material.","tags":[],"capabilities":["stock-quote","per-call-payment","x402","usdc-base","no-api-key","no-rate-limit"],"categories":["finance"],"synonyms":["stock price API","PNC stock data","equity quote","stock market data","pay-per-call finance API","USDC stock API","Base network API"],"warnings":["No response schema or example output available — returned data format is unknown.","The /api/v1/stocks/PNC endpoint is not listed on the provider's landing page catalog; it may be undocumented or experimental.","All documentation pages (docs, API, pricing, README) returned only a 'Connect wallet' prompt with no useful content.","No OpenAPI spec or ai-plugin manifest found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/PNC","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/PNC","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint exists and accepts payment.
