x402-payable research agent that answers queries via Questflow's AI swarm on Base Sepolia.
What it does
The Researcher endpoint is an x402-enabled AI agent hosted on Questflow's swarm infrastructure. It accepts a text prompt (the "input" field) via HTTP POST and returns a text response from the agent. Payment is handled through the x402 protocol using USDC on the Base Sepolia testnet, with a maximum cost of 0.5 USDC per request and a timeout of up to 1200 seconds.
Questflow 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 emphasizes trading and market scanning, this specific endpoint is labeled "Researcher," suggesting it is oriented toward information retrieval and research tasks rather than direct trade execution. However, no detailed documentation, OpenAPI spec, or usage examples are published for this endpoint beyond the x402 challenge metadata.
Because the endpoint runs on Base Sepolia (a testnet), it is likely intended for development and experimentation rather than production use. There is no published documentation page, no OpenAPI schema, and the only structured information available comes from the x402 payment challenge. Prospective users should treat this as an experimental or pre-production service.
Capabilities
Use cases

- —Integrating a pay-per-query AI researcher into an agent pipeline via x402
- —Experimenting with x402 payment flows on Base Sepolia testnet
Fit
Best for
- —Developers exploring x402 payment-gated AI endpoints
- —Agent-to-agent workflows needing a research sub-agent
- —Testing pay-per-call AI services on a testnet
Not for
- —Production workloads requiring guaranteed uptime and mainnet payments
- —Users needing detailed, documented API contracts or OpenAPI specs
- —Direct trade execution or market order placement

Request
{

}Response
{
"response": "Recent trends in DeFi lending include the rise of real-world asset (RWA) collateralization, cross-chain lending protocols, and variable-rate optimization strategies..."
}Endpoint
Quality
No OpenAPI spec, no documentation pages, no usage examples, and the endpoint runs on a testnet. The only structured metadata comes from the x402 challenge. The response schema and behavior are inferred from the outputSchema in the challenge payload.
Warnings
- —Endpoint is on Base Sepolia testnet — not suitable for production use
- —No published documentation or OpenAPI schema
- —Response format and agent behavior are inferred from minimal x402 challenge metadata
- —The example response is fabricated based on the output schema; actual responses may differ
- —maxTimeoutSeconds is 1200 (20 minutes), suggesting potentially long response times
