It is part of a broader suite of APIs offered by lowpaymentfee.com, which covers data analytics, AI/ML inference, finance/Web3 data, and utility services — all accessible via the x402 payment protocol on the Base network.\n\nThe endpoint accepts POST requests and is paid per call using USDC on Base. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request. No API keys or account registration are needed; payment is handled inline via the X-PAYMENT header. The provider advertises no rate limits and instant access.\n\nThe specific endpoint `/api/v1/tokens/GRT/price` sits within the Finance & Web3 category of the provider's API catalog, alongside other endpoints for price feeds, exchange rates, token quotes, and gas estimates. Documentation 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. The response schema and exact fields returned are not documented, so consumers should expect a JSON payload with price information but will need to inspect the actual response to confirm the structure.","tags":[],"capabilities":["token-price-lookup","grt-price","x402-payment","usdc-on-base","pay-per-call","no-api-key","crypto-market-data"],"categories":["finance","crypto"],"synonyms":["GRT price","The Graph token price","crypto price API","token price feed","GRT market data","x402 crypto API","pay-per-request price API"],"warnings":["No response schema or example response documented — consumers must discover the output format empirically.","Docs, pricing, and README pages render only 'Connect wallet' with no technical content.","The provider's broader API catalog lists many endpoints but none have detailed documentation visible in the crawl.","It is unclear whether this endpoint returns only a spot price or additional metadata (volume, market cap, etc.)."],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/GRT/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/GRT/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 ($0.02 USDC on Base).
