The site hosts a broad catalog of pay-per-request APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). Each request costs $0.02 in USDC on the Base network, with no API keys, no rate limits, and no minimum commitments required.\n\nThe specific endpoint `/api/v1/wire/58` is labeled \"Premium API Access\" and accepts HTTP POST requests. Payment is settled on-chain via USDC (contract 0x8335…2913) on Base, using the x402 \"exact\" scheme. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per call. The endpoint returns application/json responses.\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 request/response schema documentation, and no examples available. The purpose of the `/api/v1/wire/58` path specifically (as opposed to the named endpoints like `/api/v2/ai/sentiment`) is unclear; it may be a generic or internal route. Without documentation on what input this endpoint expects or what it returns, agents will need to experiment or rely on the provider for guidance.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","json-api","http-post"],"categories":["api-marketplace","infrastructure"],"synonyms":["low payment fee API","x402 API","USDC pay-per-call","Base network API","micropayment API","premium API access","wire endpoint"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all render only 'Connect wallet'","No OpenAPI or schema definition found for this endpoint","The specific purpose of /api/v1/wire/58 is unclear; it does not match any of the named endpoints listed on the homepage","No request body schema or response examples are available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/58","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/wire/58","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 accepts payments.
