The endpoint is live and returns a 402 challenge requiring payment of up to 20,000 base units of USDC (0x8335…2913) on the Base network, which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required — access is granted per-call via the x402 payment protocol.\n\nThe provider hosts a broad catalog of endpoints spanning data/analytics, AI/ML, finance/Web3, and utility services, all uniformly priced at $0.02 per request. This specific endpoint (/api/v1/tokens/LUNC) falls under the Finance & Web3 category and likely returns token-level data such as price, market cap, or related metadata for LUNC. However, no response schema or example output is documented, so the exact fields returned are unknown.\n\nPayment is made via the x402 \"exact\" scheme: the caller includes an X-PAYMENT header with a signed USDC transfer of up to $0.02 to the payTo address on Base. The maximum timeout is 300 seconds. The endpoint accepts POST requests and is marked as discoverable.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","token-data","per-call-pricing","no-api-key","crypto-market-data"],"categories":["finance","crypto"],"synonyms":["LUNC token API","Terra Classic data","crypto token price","LUNC market data","x402 crypto API","pay-per-call token data","lowpaymentfee"],"warnings":["No response schema or example output documented — the exact data returned for LUNC is unknown","Documentation pages (/docs, /pricing, /README) are effectively empty, showing only 'Connect wallet'","No OpenAPI spec or ai-plugin manifest available","The provider's catalog lists many endpoints but none have detailed documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/LUNC","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/LUNC","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 captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented response format, no example responses, and the crawled docs/pricing/README pages are all empty beyond a 'Connect wallet' prompt.
