It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering finance, crypto, AI/ML, data analytics, and utility services. All endpoints use the x402 protocol on the Base network, settling payments in USDC at $0.02 per request with no API keys, rate limits, or subscriptions required.\n\nThe specific endpoint at `/api/v1/tokens/MATIC/price` accepts POST requests and returns JSON. Payment is handled via the x402 `X-PAYMENT` header using the \"exact\" scheme, with a max amount of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on the Base network, with a timeout of 300 seconds.\n\nDocumentation beyond the landing page is sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI schema, no example responses, and no description of the response format. The endpoint is confirmed live (returns a proper 402 challenge), but the exact response payload structure is unknown.","tags":[],"capabilities":["token-price-lookup","x402-micropayment","usdc-payment","base-network","real-time-pricing","pay-per-request","no-api-key"],"categories":["finance","crypto"],"synonyms":["MATIC price API","Polygon token price","crypto price feed","token price endpoint","x402 crypto API","micropayment price API","MATIC USD price"],"warnings":["No OpenAPI or schema documentation available for this endpoint","Response payload structure is unknown — no examples found anywhere in crawled content","All doc/pricing/API/README pages render only 'Connect wallet' with no useful content","The endpoint path /api/v1/tokens/MATIC/price is not listed on the landing page (landing page lists /api/v1/crypto/quotes and /api/v1/finance/prices instead), so its exact relationship to the advertised API suite is unclear"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/MATIC/price","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/MATIC/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing and payment details.
