It is part of the lowpaymentfee.com platform, which offers a collection of x402-protocol pay-per-call APIs spanning finance, crypto, AI, and utility categories. The endpoint is accessed via HTTP POST and is gated by an x402 payment challenge settled in USDC on the Base network.\n\nPricing is $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access. The payment is directed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base.\n\nDocumentation on the site is extremely thin — 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 documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format for a successful paid request is unknown.","tags":[],"capabilities":["token-price","mkr-price","x402-payment","usdc-base","pay-per-call","crypto-market-data","no-api-key"],"categories":["finance","crypto"],"synonyms":["MKR price API","Maker token price","crypto price feed","token price lookup","MKR market data","x402 crypto API","micropayment price 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 example request or response payloads could be found","The platform hosts many diverse endpoints (AI, finance, utilities) all at $0.02 — unclear whether these are production-quality data sources or demo/placeholder services"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/MKR/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/MKR/price","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 with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
