Pay-per-message AI agent endpoint on Questflow's swarm network via x402 micropayments.
What it does
This x402-enabled endpoint exposes a Questflow "swarm" agent that accepts a text message and returns a text response, gated behind an on-chain micropayment on Base Sepolia using USDC. The endpoint follows the x402 payment protocol (version 1): callers must include an X-PAYMENT header to satisfy the payment challenge before the agent processes the request.
The underlying platform, Questflow, markets itself as an "AI Clone" system that aggregates prediction markets and on-chain trading venues (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover alpha and execute trades autonomously. However, the specific capabilities of this particular swarm agent are unclear — the listing is titled "Personal use" with no further documentation, no OpenAPI spec, and no /docs endpoint. The input schema accepts a single string field ("input") and returns a single string field ("response").
Payment is required in USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e) on the Base Sepolia testnet, with a maximum amount of 500000 (likely 0.50 USDC given 6 decimals) per request and a timeout of up to 1200 seconds. Because this runs on a testnet, it is likely a development or demo endpoint rather than a production service.
Capabilities
Use cases
- —Sending a paid text query to a Questflow AI agent and receiving a text response
- —Testing x402 payment-gated agent interactions on Base Sepolia testnet
- —Integrating autonomous AI agent capabilities into crypto-native workflows
Fit
Best for
- —Developers experimenting with x402 payment protocol integrations
- —Testing pay-per-message AI agent patterns on a testnet
- —Exploring Questflow's swarm agent infrastructure
Not for
- —Production workloads requiring mainnet settlement and SLAs
- —Users needing detailed API documentation or predictable agent behavior
- —Non-crypto use cases where payment gating adds unnecessary friction

"response": "Here are the current top prediction markets across Polymarket and Opinion Labs..."
}Endpoint
Quality
No OpenAPI spec, no documentation endpoint, no usage examples, and the listing title/description are generic ('Personal use'). The only structured information comes from the x402 challenge payload. The endpoint runs on a testnet, suggesting it is not production-ready.
Warnings
- —Endpoint is on Base Sepolia testnet — not suitable for production use
- —No API documentation or OpenAPI spec available
- —Agent capabilities and behavior are entirely undocumented
- —The listing title 'Personal use' provides no meaningful description
- —Response example is inferred/fabricated since no live response was captured
- —maxAmountRequired of 500000 likely means 0.50 USDC (6 decimals) but this is inferred
