Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The payment is settled on-chain to a specified wallet address using the \"exact\" scheme.\n\nThe provider operates a broader platform offering dozens of pay-per-call endpoints spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request and use the same x402 payment flow on Base with USDC.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for the stocks endpoint. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data source and response format are unknown.","tags":[],"capabilities":["stock-quote","x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key"],"categories":["finance","data"],"synonyms":["stock price API","SBUX stock data","Starbucks stock quote","x402 stock API","crypto-paid stock API","micropayment stock data"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content","No OpenAPI or schema describing the response format for the /api/v1/stocks/SBUX endpoint","Response data source and freshness are unknown — unclear whether this returns real-time or delayed stock quotes","The provider lists many endpoint categories but specifics on data quality, uptime, or SLAs are absent"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/SBUX","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/SBUX","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payment.
