It is accessed via an HTTP POST request with a JSON body containing an \"input\" string message. Payment is handled through the x402 protocol on the Base Sepolia testnet using USDC, with a maximum amount of 100,000 units (likely 0.10 USDC given 6-decimal USDC). The agent processes the input and returns a string response.\n\nQuestflow is a platform focused on autonomous AI agents (\"Clones\") that operate across onchain markets. This particular agent appears to be a utility agent for programmatic email sending rather than a trading agent. The endpoint is on a development/staging API domain (api-dev), which suggests it may not be production-ready. No OpenAPI schema, dedicated documentation, or pricing page was found beyond the x402 challenge metadata.\n\nThe x402 challenge specifies the payment address, asset (USDC on Base Sepolia at 0x036CbD53842c5426634e7929541eC2318f3dCF7e), and a maximum timeout of 1200 seconds. The output schema is minimal: a single \"input\" string field in the request and a single \"response\" string field in the reply. No further details about email formatting, recipient specification, or rate limits are documented.","tags":[],"capabilities":["email-sending","x402-payment","base-sepolia-usdc","ai-agent","http-post"],"categories":["email","automation"],"synonyms":["send email API","programmatic email","no-reply email agent","questflow email","x402 email endpoint","email automation agent"],"warnings":["Endpoint is on a development domain (api-dev) and uses Base Sepolia testnet — not production-ready.","No documentation, OpenAPI spec, or usage guide found.","Email sending behavior (recipient, subject, body formatting) is entirely undocumented — the agent presumably parses natural language input.","The example response is fabricated for illustration; actual response format is unknown.","USDC asset is on testnet (Base Sepolia) so real monetary value is not involved."],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:682303bfd973977d61d66a38","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x4281fFcFdaAeff670eCACd7555BFF502D657B670","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:682303bfd973977d61d66a38","description":"Can send email using no-reply@questflow.ai other mail address. | 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":"0.250","qualityRationale":"Only the x402 challenge metadata is available; there is no OpenAPI spec, no dedicated documentation, no usage examples, and the endpoint is on a dev/staging domain using testnet tokens.
