Pay-per-message AI agent endpoint on Questflow's swarm network via x402 micropayments
What it does
This is an x402-enabled endpoint hosted on Questflow's development API that exposes a conversational AI agent ("swarm" agent) accessible via micropayments on the Base Sepolia testnet. The endpoint accepts a POST request with a JSON body containing an `input` string (your message to the agent) and returns a `response` string from the agent. Payment is handled via the x402 protocol using USDC on Base Sepolia, with a maximum amount of 500,000 units (likely 0.50 USDC given 6-decimal USDC).
Questflow is a platform focused on autonomous AI agents ("Clones") that aggregate onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. The platform enables agents to scan markets, execute trades, and generate revenue autonomously. This particular endpoint appears to be a general-purpose personal-use agent within Questflow's swarm infrastructure, though the exact capabilities of the agent behind this endpoint are not documented beyond the generic "Personal use" label.
Note that this is a development/testnet endpoint (api-dev, base-sepolia), so it is likely intended for testing and experimentation rather than production use. No OpenAPI spec, detailed documentation, or usage examples are provided by the host. The endpoint is live and returns a valid x402 challenge on POST requests.
Capabilities
Use cases

- —Integrating autonomous AI agent capabilities into workflows via HTTP POST
Fit
Best for
- —Developers experimenting with x402 payment protocol
- —Testing pay-per-message AI agent interactions on testnet
- —Exploring Questflow's swarm agent infrastructure
Not for
- —Production workloads requiring guaranteed uptime (this is a dev/testnet endpoint)
- —Users needing detailed documentation or guaranteed agent capabilities
- —Free or non-crypto payment access to AI agents

"response": "I can help you with various tasks. How can I assist you today?"
}Endpoint
Quality
The endpoint is live and returns a valid x402 challenge with a defined outputSchema, but there is no OpenAPI spec, no documentation, no usage examples, and the agent's actual capabilities are entirely undocumented beyond 'Personal use'. This is a dev/testnet endpoint with minimal information available.
Warnings
- —Development/testnet endpoint (api-dev, base-sepolia) — not intended for production use
- —No documentation, OpenAPI spec, or usage examples provided by the host
- —Agent capabilities behind this endpoint are completely undocumented
- —The response example is inferred from the outputSchema and not from actual observed output
