Pay-per-message AI agent on Questflow's swarm network via x402 micropayments
What it does
This endpoint exposes a Questflow-hosted AI agent (swarm) behind the x402 payment protocol. Callers send a POST request with a text message in the `input` field and receive a text `response` from the agent. Payment is handled via an X-PAYMENT header using USDC on the Base Sepolia testnet, with a maximum charge of 0.50 USDC per request (6-decimal token, maxAmountRequired = 500000).
Questflow is a platform for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) for trading, signal generation, and revenue earning. This particular endpoint is labeled "new project" and appears to be a generic or newly created agent instance. No further documentation, OpenAPI spec, or detailed capability description is available for this specific agent beyond the x402 challenge metadata.
Because this is on Base Sepolia (a testnet), the USDC payments are not real money. The endpoint is live and returns a proper 402 challenge, but the lack of documentation about what the agent actually does, combined with the generic "new project" name, means callers should treat this as an experimental or development-stage endpoint.
Capabilities
Use cases
- —Sending a text prompt to a Questflow AI agent and receiving a response via x402 micropayment
- —Testing x402 payment protocol integration with an AI agent on Base Sepolia testnet
- —Programmatic agent-to-agent communication with per-request USDC payments
Fit
Best for
- —Developers experimenting with x402 payment protocol for AI agents
- —Testing micropayment-gated AI endpoints on a testnet
- —Exploring Questflow's swarm agent infrastructure
Not for
- —Production workloads requiring guaranteed uptime and SLAs
- —Users needing detailed agent capabilities or domain-specific expertise
- —Anyone expecting mainnet real-money transactions (this is testnet)

}Endpoint
Quality
The endpoint is live and returns a valid x402 challenge with an output schema, but there is no OpenAPI spec, no documentation, no examples, and the agent is generically named "new project" with no description of its actual capabilities. The response example is entirely inferred. This is effectively a stub listing.
Warnings
- —No OpenAPI or documentation available for this endpoint
- —Agent is labeled 'new project' with no description of its specific capabilities
- —Runs on Base Sepolia testnet — USDC payments are not real money
- —The example response is fabricated/inferred since no actual response was observed
- —The dev subdomain (api-dev) suggests this is a development/staging environment
