Query financial datasets via an x402-payable AI agent on Questflow
What it does
This endpoint exposes an AI agent on the Questflow platform that provides access to financial datasets through the x402 payment protocol. Callers send a POST request with a natural-language message in the `input` field, pay per-request in USDC on the Base network, and receive a text response from the agent.
The agent is identified by the QRN `qrn:agent:6896c8469b0e5b463f620fcf` and is described as providing access to a "remote MCP server for Financial Datasets." Beyond that label, no further documentation specifies which financial datasets are available, what query formats are supported, or what the response schema looks like in detail. The x402 challenge indicates a maximum payment of 100,000 units of USDC (asset `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base) with a timeout of up to 1,200 seconds. The payment recipient is `0xd3714949b5B6b9d55ee1D89Aa6776907aa4920F7`.
Questflow is a platform focused on autonomous AI agents ("Clones") that operate across on-chain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. This particular agent appears to be a data-retrieval agent rather than a trading agent. Because there is no OpenAPI spec, no dedicated documentation page, and no example responses available, the exact capabilities and data coverage of this agent remain unclear.
Capabilities
Use cases
- —Querying financial market data on demand with per-request USDC micropayments
- —Integrating financial dataset lookups into autonomous AI agent workflows
- —Accessing financial datasets from an MCP-compatible server without managing credentials
Fit
Best for
- —Developers building x402-native agent pipelines that need financial data
- —On-chain applications requiring pay-per-use financial dataset access
- —AI agents that need to fetch financial information programmatically
Not for
- —Users who need clearly documented schemas and guaranteed SLAs for financial data
- —High-frequency trading systems requiring sub-second latency
- —Free or bulk-download financial data needs

Quality
No OpenAPI spec, no dedicated docs, no example responses, and no details on which financial datasets are available. The only concrete information comes from the x402 challenge metadata and the agent's short description. The response example above is entirely inferred.
Warnings
- —No documentation or OpenAPI schema available — /docs, /api, /pricing, /README all return 404
- —Exact financial datasets accessible through this agent are unspecified
- —maxAmountRequired of 100000 USDC units — actual cost per request is unclear (could be micro-units or full USDC)
- —Response format and content are inferred; no real example response was available
- —The agent description says 'MCP server for Financial Datasets' but no MCP tool listing is exposed
