Callers send a POST request with a text message and receive a text response from the agent. Payment is handled inline using USDC on the Base network, with a maximum charge of 0.1 USDC per request (the asset has 6 decimals, so maxAmountRequired of 100000 = 0.1 USDC). The endpoint uses the x402 \"exact\" payment scheme and supports a timeout of up to 1200 seconds.\n\nQuestflow is a platform focused on autonomous AI agents (\"Clones\") that aggregate onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. While the broader platform centers on trading and market-scanning agents, this specific endpoint is labeled \"daydreams mcp server\" and functions as a simple message-in / response-out agent interface. No further documentation about the agent's specific capabilities, personality, or domain expertise is available beyond the title.\n\nThe endpoint is live and returns a valid x402 challenge on POST. However, there is no OpenAPI spec, no dedicated documentation page, and no examples of actual agent responses. The agent's behavior, knowledge domain, and quality of responses are unknown from the available material.","tags":[],"capabilities":["x402-payment","conversational-agent","usdc-base-payment","post-message-response","autonomous-agent"],"categories":["llm","crypto"],"synonyms":["daydreams agent","questflow agent","x402 chat agent","pay-per-message AI","questflow mcp","onchain AI agent","USDC agent endpoint"],"warnings":["No API documentation or OpenAPI spec available","Agent behavior, domain expertise, and response quality are completely unknown","The name 'daydreams mcp server' is unexplained — unclear what 'daydreams' refers to","Example response is fabricated for illustration; actual output is unknown","No rate limits, SLA, or uptime guarantees documented"],"endpointUrl":"https://api.questflow.ai/x402/agent/qrn:agent:6901eecfa190739b272f5d57","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0xdF714EC6C622F905cb53E66E3f0CdE09087D51d5","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/agent/qrn:agent:6901eecfa190739b272f5d57","description":"daydreams mcp server | 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":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with a clear outputSchema, but there is no documentation, no OpenAPI spec, no usage examples, and no information about what the agent actually does beyond its name.
