It is accessed via the x402 payment protocol: each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required. The caller simply attaches an X-PAYMENT header with a valid payment proof to receive the response.\n\nThe provider hosts a wide catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services—all priced uniformly at $0.02 per request. This specific endpoint (`/api/v1/tokens/KLAY`) sits in the crypto/finance category and likely returns token metadata or pricing information for KLAY. The x402 challenge confirms the endpoint is live, accepts POST requests, and settles payments to a known USDC contract on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).\n\nDocumentation beyond the landing page is essentially empty (all sub-pages just show \"Connect wallet\"), so the exact response schema, supported query parameters, and detailed field definitions are unknown. The endpoint is functional and correctly issues a 402 challenge, but consumers should expect to experiment with request bodies to discover the full API surface.","tags":[],"capabilities":["token-data","crypto-market-data","x402-payment","base-network","usdc-settlement","pay-per-request"],"categories":["finance","crypto"],"synonyms":["KLAY token API","Klaytn token data","crypto token lookup","token price API","x402 crypto API","micropayment API","lowpaymentfee"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet' with no content.","Response schema for /api/v1/tokens/KLAY is undocumented; consumers must discover fields experimentally.","The provider lists many endpoints across diverse categories (AI, analytics, finance, utilities) all at $0.02 — quality and depth of each is unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/KLAY","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/KLAY","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no example responses, and all doc/pricing/API pages are empty stubs.
