Questflow Swarm agent endpoint: send a message, get an AI agent response via x402 micropayment.
What it does
This is an x402-enabled endpoint hosted by Questflow on their development API server. It exposes a single POST method that accepts a text message (the `input` field) and returns a string response from an AI agent within the Questflow Swarm system. Payment is required via 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 for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover trading alpha, execute trades, and generate revenue. This particular endpoint appears to be a development/testnet instance of a swarm agent, identified by the QRN `qrn:swarm:68f8b26f88e91d0ba6c9abe2`. The endpoint's own description is placeholder text, providing no detail about the specific agent's purpose or specialization.
Because the endpoint description is explicitly placeholder text and no additional documentation, OpenAPI spec, or usage examples are available, the actual behavior and capabilities of this agent are unknown. The endpoint is live and returns a valid x402 challenge, but prospective callers should be aware this is a dev-environment endpoint on a testnet and may be unstable or subject to change.
Capabilities
Use cases
- —Sending a text prompt to a Questflow swarm AI agent and receiving a response
- —Programmatic agent-to-agent communication via x402 micropayments
- —Testing x402 payment flows on Base Sepolia testnet
Fit
Best for
- —Developers experimenting with x402 payment protocol on testnet
- —Agent-to-agent communication requiring micropayment gating
- —Exploring Questflow's swarm agent capabilities
Not for
- —Production workloads (this is a dev/testnet endpoint)
- —Users needing documented, well-specified API contracts
- —Anyone expecting free or non-crypto-payment access
Quick start
curl -X POST https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f8b26f88e91d0ba6c9abe2 \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <your-x402-payment-header>" \
-d '{"input": "What markets are trending today?"}'Example
Request
{
"input": "What markets are trending today?"
}Response
{
"response": "Currently trending markets include ETH price predictions on Polymarket and several new token launches on Pump.fun."
}Endpoint
Quality
The endpoint is live and returns a valid x402 challenge with a defined outputSchema, but the description is explicitly placeholder text, there is no documentation, no OpenAPI spec, and no usage examples. This is a dev/testnet endpoint with minimal information available.
Warnings
- —Endpoint description is placeholder text with no substantive information about the agent's purpose
- —This is a development endpoint (api-dev) on Base Sepolia testnet — not production
- —No OpenAPI spec, documentation, or usage examples available
- —Response example is inferred from the outputSchema, not from actual observed output
- —Max timeout of 1200 seconds suggests potentially long-running agent tasks
