Each request 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.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. This specific endpoint sits under the /api/v1/stocks/ path and is parameterized by ticker symbol (ABT in this case). The x402 challenge confirms the endpoint is live and accepts USDC (contract 0x8335…2913) on Base with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the stated mimeType of application/json. The endpoint is confirmed live via the 402 challenge, but the actual data quality, coverage, and response structure remain unknown.","tags":[],"capabilities":["stock-data","per-call-payment","x402-protocol","usdc-settlement","base-network","no-api-key","ticker-lookup"],"categories":["finance","data"],"synonyms":["stock price API","ABT stock data","equity data endpoint","pay-per-call stock API","x402 stock API","Abbott Laboratories stock","ticker data API"],"warnings":["No documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no technical content","No OpenAPI or output schema provided; response format for stock data is unknown","No example responses available to verify data quality or coverage","The endpoint path suggests per-ticker routing (/stocks/ABT) but it is unclear which tickers are supported"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/ABT","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/ABT","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), but there is no OpenAPI schema, no documented request/response format, no examples, and the docs pages are empty stubs.
