It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3 data, and utility services. Each request costs $0.02 in USDC (USD Coin) on Base, settled on-chain with no API keys, no rate limits, and no subscriptions required.\n\nThe specific endpoint `/api/v1/tokens/TRX/price` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02. Payment is made via the x402 \"exact\" scheme to the specified payTo address. The broader site lists many similar endpoints at the same price point, all following the same x402 payment flow.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint appears functional based on the 402 challenge, but the exact response format must be inferred from the endpoint path and common conventions for token price APIs.","tags":[],"capabilities":["token-price","trx-price","x402-payment","usdc-on-base","pay-per-request","no-api-key","crypto-market-data","real-time-pricing"],"categories":["finance","crypto"],"synonyms":["TRX price API","Tron token price","crypto price feed","token price lookup","TRX market data","cryptocurrency price endpoint","x402 crypto API"],"warnings":["No OpenAPI or schema documentation available — response format is entirely unknown","All doc pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content","The specific /api/v1/tokens/TRX/price path is not listed on the homepage; only /api/v1/crypto/quotes and /api/v1/finance/prices are shown, so this endpoint may be undocumented or dynamically routed","No example responses available to verify data quality or structure"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/TRX/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/TRX/price","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 documented request/response schema, no example payloads, and all documentation pages are blank beyond a wallet-connect prompt.
