It accepts a natural-language message (POST with an `input` string field) and returns crypto market intelligence sourced from CoinGecko — including price feeds, market data, asset metadata, NFT data, exchange information, and historical pricing.\n\nPayment is handled through an x402 challenge on the Base Sepolia testnet using USDC (contract `0x036CbD53842c5426634e7929541eC2318f3dCF7e`). The maximum amount required per request is 100,000 units (in the token's smallest denomination), with a timeout of up to 1,200 seconds. The agent is conversational: you send a plain-text query and receive a plain-text response.\n\nThe endpoint is live and returns a valid 402 challenge. However, documentation is minimal — there is no OpenAPI spec, no dedicated docs page, and the only schema available is the one embedded in the x402 challenge itself. The hosting platform (Questflow / dctx.link) is primarily an AI-clone trading platform; this agent appears to be one of many agents available through their x402 gateway. Because the network is Base Sepolia (a testnet), this endpoint is likely intended for development or experimentation rather than production use.","tags":[],"capabilities":["crypto-price-feeds","market-data","historical-data","nft-data","exchange-data","natural-language-query","x402-payment","base-sepolia-usdc","conversational-agent"],"categories":["crypto","market-data","agent"],"synonyms":["CoinGecko API","crypto price API","cryptocurrency market data","token price feed","NFT market data","exchange data API","Questflow agent","x402 crypto agent"],"warnings":["Payment network is Base Sepolia (testnet) — not suitable for production use","No OpenAPI spec or dedicated documentation available","Response format and content are inferred from schema description only; no actual response was observed","The example response JSON is illustrative and not sourced from a real call","Agent behavior and CoinGecko data coverage details are unspecified"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:68f59a6a93d1a55ee56c7d3b","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0xac50fAa18Ec8e6c165f3CC4C6Ed4bc66fc47F2FF","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:68f59a6a93d1a55ee56c7d3b","description":"Coingecko provides abilities to obtain price feeds, market data, metadata, and historical data of crypto assets, NFTs, and exchanges. | Powered by Questflow","outputSchema":{"input":{"type":"http","method":"POST","bodyFields":{"input":{"type":"string","required":true,"description":"Your message to the agent"}},"discoverable":true},"output":{"response":{"type":"string","required":true,"description":"Response from the agent"}}},"maxAmountRequired":"100000","maxTimeoutSeconds":1200}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with an embedded schema.
