The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or upfront commitments are required — each call is individually paid via the x402 protocol's X-PAYMENT header.\n\nThe provider (lowpaymentfee.com) hosts a broad catalog of similarly priced endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. The specific endpoint `/api/v1/tokens/MINA` falls under the Finance & Web3 category and likely returns price or market information for the MINA token, though the exact response schema is not documented. The site's docs, pricing, and API pages all require a wallet connection and provide no additional technical detail beyond what the landing page shows.\n\nBecause no OpenAPI spec, response schema, or usage examples are published, consumers should treat this as a lightly documented endpoint. The x402 challenge is live and well-formed, confirming the endpoint is operational. The payment timeout is 300 seconds.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","token-data","mina-token","pay-per-call","json-response"],"categories":["finance","crypto"],"synonyms":["MINA price API","Mina Protocol token data","crypto token quotes","MINA market data","x402 crypto API","pay-per-request token API"],"warnings":["No OpenAPI or response schema published — actual response format is unknown","Documentation pages (/docs, /api, /pricing, /README) are effectively empty, showing only a wallet-connect prompt","Exact request body parameters (if any) are undocumented","No SLA, uptime, or rate-limit guarantees documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/MINA","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/MINA","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint works and pricing is clear ($0.02 USDC on Base).
