The payment is $0.02 per request in USDC, with no API keys, rate limits, or subscriptions required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe endpoint is part of a broader suite of APIs offered at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3 market data, and utility services — all priced at $0.02 per call. This specific endpoint lives under the Finance & Web3 category and is designed for agents or applications that need on-demand token pricing without traditional API key management. The x402 challenge confirms the endpoint is live, accepts POST requests, and settles payments to a specified address on Base using USDC (contract 0x8335…2913).\n\nDocumentation beyond the landing page is minimal — the /docs, /pricing, and /README pages all resolve to a wallet-connect stub with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The actual data source for SUSHI pricing is not disclosed.","tags":[],"capabilities":["token-price","crypto-market-data","x402-payment","base-network","usdc-settlement","no-api-key","per-request-billing"],"categories":["finance","crypto"],"synonyms":["SUSHI price API","SushiSwap token price","crypto price feed","token price lookup","x402 crypto API","micropayment price API","SUSHI USD price"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","Docs, pricing, and README pages all resolve to an empty wallet-connect page with no content","Data source for SUSHI token price is not disclosed; accuracy and freshness are unverifiable","No SLA, rate-limit, or uptime guarantees documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/SUSHI/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/SUSHI/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty stubs.
