It uses the x402 payment protocol, accepting USDC payments on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid payment proof.\n\nThe provider offers a range of endpoints across data analytics, AI/ML inference, finance/crypto, and infrastructure utilities, all priced uniformly at $0.02 per call. This specific endpoint (`/api/v1/wallet/CELO/balance`) appears to return balance information for a CELO wallet, though the exact request and response schemas are not documented beyond the x402 challenge metadata.\n\nPayment is settled on the Base L2 network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The endpoint accepts POST requests and returns application/json. The x402 challenge confirms the endpoint is live and discoverable.","tags":[],"capabilities":["wallet-balance","celo-blockchain","x402-payment","usdc-base-network","crypto-data","per-request-pricing"],"categories":["crypto","finance"],"synonyms":["CELO balance API","wallet balance check","crypto balance lookup","CELO account balance","blockchain wallet query"],"warnings":["No documented request or response schema available","Documentation pages (/docs, /pricing, /README) return only 'Connect wallet' with no useful content","Response format is entirely inferred — no example responses available","The specific functionality of this endpoint (what wallet address format, what balance fields are returned) is not documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wallet/CELO/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/CELO/balance","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The x402 challenge is live and confirms pricing, network, and asset.
