Each call costs $0.02 (20,000 base units of USDC on the Base network, where USDC uses 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to receive a JSON response.\n\nThe endpoint is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services, all priced uniformly at $0.02 per request. The specific `/api/v1/tokens/XRP` path suggests it returns token-level data for XRP, likely including price or market information, though the exact response schema is not documented.\n\nThe x402 challenge is live and confirms payment is accepted in USDC (contract 0x8335…2913) on Base mainnet, with a 300-second payment timeout. There is no OpenAPI spec, no detailed documentation, and the docs/pricing/API pages all render only a \"Connect wallet\" prompt, so the precise request parameters and response format remain unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","token-data","xrp-data","pay-per-call","no-api-key"],"categories":["finance","crypto"],"synonyms":["XRP price API","XRP token data","crypto token endpoint","x402 crypto API","pay-per-call token data","XRP market data","micropayment API"],"warnings":["No OpenAPI or schema documentation available — request parameters and response format are unknown","All doc/pricing/API pages return only a 'Connect wallet' prompt with no substantive content","The exact data returned for /api/v1/tokens/XRP is inferred from the URL path; it could be price data, metadata, or something else","Platform appears to be a generic template with many endpoints; quality and reliability of underlying data sources is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/XRP","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/XRP","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, and all documentation pages render only a wallet-connect prompt.
