Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller sends an X-PAYMENT header containing a signed USDC payment, and the endpoint returns JSON stock data.\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call endpoints spanning data analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and utility services (geocoding, validation, conversion, generation). All endpoints share the same $0.02-per-request pricing model settled on Base via USDC. The specific endpoint probed here (`/api/v1/stocks/TMO`) falls under the finance category but is not explicitly listed on the landing page, suggesting the stocks path may accept arbitrary ticker symbols.\n\nDocumentation is extremely thin — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The x402 challenge is live and well-formed, confirming the endpoint is operational, but the lack of documentation makes it difficult to know what fields the response contains or what POST body (if any) is expected.","tags":[],"capabilities":["stock-data","x402-payment","usdc-settlement","base-network","per-call-pricing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price API","equity data endpoint","TMO stock quote","pay-per-call stock data","x402 stock API","USDC stock API","Thermo Fisher stock data","lowpaymentfee stocks"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all render only a wallet-connect prompt","No OpenAPI or schema definition for request or response payloads","The /api/v1/stocks/TMO path is not listed on the provider's landing page; it may be undocumented or dynamically routed","Response format and fields are completely unknown — no example responses available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/TMO","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/TMO","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 works and costs $0.02 USDC on Base.
