It is part of a broader suite of APIs offered by the provider covering data analytics, AI/ML inference, finance/Web3 market data, and utility services, all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/tokens/CAKE` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header with a signed USDC payment of up to 0.02 USDC (maxAmountRequired=20000 base units, USDC has 6 decimals) to the payTo address on Base. No API keys, rate limits, or upfront commitments are required — each call is independently paid.\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 example request/response payloads, and no description of the response schema for this token endpoint. The endpoint is confirmed live (returns a valid 402 challenge), but the actual data returned after payment is unknown from available materials.","tags":[],"capabilities":["token-data","crypto-market-data","x402-micropayment","usdc-payment","base-network","per-request-billing","no-api-key"],"categories":["finance","crypto"],"synonyms":["CAKE token price","PancakeSwap token data","crypto token API","token quote","x402 crypto API","micropayment API","Base USDC API"],"warnings":["No OpenAPI or schema documentation available — response format is entirely unknown","All doc/pricing/API pages return only a 'Connect wallet' prompt with no technical content","No example requests or responses available; the token data fields returned after payment are unverified","The provider lists many API categories (AI, analytics, finance, utilities) all at $0.02 — breadth vs. depth is unclear"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/CAKE","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/CAKE","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).
