The endpoint is live and returns a 402 challenge requiring payment of 20,000 base units of USDC (USD Coin, 6 decimals) on the Base network, which equals $0.02 per request. No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment to receive the response.\n\nThe provider hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request on the Base network. This specific endpoint (`/api/v1/tokens/WIF`) falls under the Finance & Web3 category and likely returns token quote or market data for the WIF token, though the exact response schema is not documented.\n\nDocumentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no response schema, and no example responses available. The endpoint accepts POST requests and returns application/json according to the x402 challenge metadata.","tags":[],"capabilities":["x402-payment","crypto-token-data","usdc-base-network","pay-per-request","no-api-key","json-response"],"categories":["crypto","finance"],"synonyms":["WIF token price","dogwifhat data","crypto token API","WIF market data","x402 crypto API","token quotes","memecoin data"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet'","No OpenAPI or response schema provided; the exact structure and content of the WIF token response is unknown","The endpoint description is generic ('Premium API Access') and does not describe what token data is returned","Cannot verify what data fields are included in the response without making a paid request"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/WIF","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/WIF","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 OpenAPI spec, no response schema, no example responses, and all documentation pages are empty beyond a wallet-connect prompt.
