It is part of a broader suite of APIs offered by lowpaymentfee.com covering data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.\n\nThe specific endpoint `/api/v1/tokens/DAI/price` accepts POST requests and returns JSON. Payment is settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base L2 network using the x402 \"exact\" scheme. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment is directed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.\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 technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format after successful payment is unknown.","tags":[],"capabilities":["token-price","dai-price","x402-payment","usdc-settlement","base-network","micropayment-api","crypto-market-data","json-response"],"categories":["finance","crypto"],"synonyms":["DAI price API","DAI token price","stablecoin price feed","crypto price endpoint","DAI USD price","token price lookup","x402 crypto API"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content","No request body schema provided; unclear if any parameters are accepted","The endpoint path suggests DAI-specific pricing but no details on data source, update frequency, or fields returned"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/DAI/price","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/tokens/DAI/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing.
