It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML, finance/Web3, and infrastructure categories — all gated behind the x402 payment protocol on the Base network.\n\nThe specific endpoint `/api/v1/wallet/CHZ/balance` accepts POST requests and is priced at 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per call (USDC uses 6 decimals). Payment is made via the x402 exact scheme with no API keys, no rate limits, and no subscriptions required. The x402 challenge was successfully captured, confirming the endpoint is live.\n\nDocumentation on the site is extremely thin — 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 request/response schema, and no usage examples provided by the platform. The endpoint's actual input parameters (e.g., whether a wallet address is passed in the POST body or as a path parameter) and response format are unknown and must be discovered experimentally.","tags":[],"capabilities":["wallet-balance-query","chz-chiliz","x402-payment","usdc-base-network","crypto-data","pay-per-request"],"categories":["crypto","finance"],"synonyms":["CHZ balance","Chiliz wallet balance","crypto wallet balance API","x402 crypto API","Base network API","micropayment API","Web3 balance check"],"warnings":["No OpenAPI or schema documentation available — request body format and response structure are unknown","All documentation pages (docs, API, pricing, README) render only a 'Connect wallet' prompt with no content","The example request JSON is inferred/guessed; actual required fields are unconfirmed","The platform lists many endpoint categories but specifics on this wallet balance endpoint are absent"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wallet/CHZ/balance","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/wallet/CHZ/balance","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 documentation, no request/response schema, and no examples.
