The endpoint is live and returns a 402 challenge requiring payment of 20,000 base units of USDC (USD Coin, 6 decimals) on the Base network, which equals $0.02 per request. Payment is made via the x402 \"exact\" scheme to the specified wallet address, with no API keys or rate limits required.\n\nThe provider lowpaymentfee.com hosts a broad catalog of x402-gated endpoints spanning data & analytics, AI & ML (sentiment, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are uniformly priced at $0.02 per call. This specific endpoint (`/api/v1/tokens/CHZ`) appears to serve token-level data for the CHZ cryptocurrency, though the exact response schema is not documented.\n\nDocumentation is extremely sparse — 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 what fields the CHZ token endpoint returns. The endpoint is confirmed live via the 402 challenge, but the actual data payload is unknown without making a paid request.","tags":[],"capabilities":["x402-payment","crypto-token-data","usdc-base-network","pay-per-request","no-api-key"],"categories":["crypto","finance"],"synonyms":["CHZ token data","Chiliz API","crypto token info","x402 token endpoint","micropayment API","Base network USDC","token quotes"],"warnings":["No API documentation available — docs, pricing, and README pages are empty","Response schema for /api/v1/tokens/CHZ is entirely unknown","No OpenAPI or ai-plugin manifest provided","Cannot verify what data is actually returned without making a paid request"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/CHZ","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/CHZ","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no example responses, and the actual data returned is completely unknown.
