It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure APIs, all priced at $0.02 per request settled in USDC on the Base network. The specific endpoint `/api/v1/tokens/AAVE` falls under the Finance & Web3 category and likely returns market or reference data for the AAVE token.\n\nPayment is handled via the x402 exact-payment scheme: callers attach an `X-PAYMENT` header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the address `0x1A2B…85F3` on Base. No API keys, accounts, or rate limits are advertised — access is purely transactional. The response MIME type is `application/json`.\n\nDocumentation on the site is extremely thin. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no example request/response, and no description of the response schema. The endpoint is confirmed live (returns a valid 402 challenge), but the actual data payload and its fields are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","token-data","pay-per-request","no-api-key","json-response"],"categories":["finance","crypto"],"synonyms":["AAVE token price","AAVE market data","crypto token API","AAVE data endpoint","x402 crypto API","pay-per-call token data","AAVE quote"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.","Response schema for /api/v1/tokens/AAVE is completely unknown; no examples or field descriptions exist.","The platform lists many diverse endpoints (AI, analytics, finance, infrastructure) all at the same price, which may indicate a demo or placeholder service rather than production-grade APIs.","No SLA, rate-limit, or uptime guarantees documented."],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/AAVE","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/AAVE","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 clear pricing ($0.02 USDC on Base).
