Pay-per-message AI agent endpoint on Questflow's swarm network (Base Sepolia testnet)
What it does
This x402-enabled endpoint exposes a conversational AI agent hosted on Questflow's swarm infrastructure. Callers send a text message via POST and receive a text response from the agent. Payment is handled through the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.5 USDC per request (6-decimal token, so 500000 raw units).
Questflow is a platform for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover alpha, execute trades, and generate revenue. This particular endpoint is labeled "Personal use" and appears to be a single agent within Questflow's swarm system, identified by the QRN `qrn:swarm:68ef7b69edb2088cc0ddd8c7`. The endpoint is live and returns a proper 402 challenge when called without payment.
Documentation is extremely sparse — there is no OpenAPI spec, no dedicated docs page, and no detailed description of what this specific agent does beyond accepting a string input and returning a string response. The endpoint runs on a development API server (`api-dev`), suggesting it may be experimental or pre-production. Pricing is in testnet USDC, so no real funds are at risk, but this also means the endpoint is not suitable for production use cases.
Capabilities
Use cases
- —Sending a text query to a Questflow AI agent and receiving a text response
- —Testing x402 payment flows on Base Sepolia testnet
- —Integrating autonomous agent capabilities into workflows via HTTP
Fit
Best for
- —Developers experimenting with x402 payment protocol on testnet
- —Testing pay-per-message AI agent interactions
- —Exploring Questflow's swarm agent infrastructure
Not for
- —Production workloads requiring mainnet payments and SLAs
- —Users needing detailed API documentation or guaranteed uptime
- —Complex multi-turn conversation sessions (no session state documented)
Quick start

-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402-payment-header>" \
-d '{"input": "Hello, what can you do?"}'Example
Request
{
"input": "Hello, what can you do?"
}Response
{
"response": "I can help you discover market opportunities across Polymarket, Pump.fun, and other onchain markets."
}Endpoint
Quality
The endpoint is live (402 challenge confirmed) with a basic outputSchema, but there is no OpenAPI spec, no dedicated documentation, no examples, and the description is just "Personal use". The endpoint runs on a dev server with testnet tokens, suggesting pre-production status. Most listing details had to be inferred from the x402 challenge and the Questflow landing page.
Warnings
- —Endpoint is on a development server (api-dev) — may be unstable or experimental
- —Payment uses Base Sepolia testnet USDC — not real funds, not production-ready
- —No API documentation, OpenAPI spec, or usage examples available
- —Agent purpose is undocumented beyond the generic label 'Personal use'
- —The specific capabilities of this individual swarm agent are unknown
