It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform share a uniform $0.02-per-request pricing model settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/market/quote/ABBV` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payee address on Base. No API keys, subscriptions, or rate limits are advertised — access is purely transactional.\n\nDocumentation beyond the landing page is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI schema, no example request/response payloads, and no description of the response fields for this market-quote endpoint. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data source and response structure are unknown.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-base","pay-per-request","micropayment"],"categories":["finance","market-data"],"synonyms":["ABBV stock quote","AbbVie market data","stock price API","equity quote endpoint","x402 finance API","micropayment stock data"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'","No OpenAPI or JSON schema describing request parameters or response fields","Data source for market quotes is unknown; no guarantees on freshness, accuracy, or coverage","Response structure must be discovered empirically; example_request_json and example_response_json cannot be provided"],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/ABBV","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/market/quote/ABBV","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 and pricing is clear ($0.02 USDC on Base).
