Pay-per-call AI agent endpoint on Questflow's swarm platform via x402 micropayments.
What it does
This is an x402-enabled endpoint hosted on Questflow's development API (api-dev.intra-tls2.dctx.link). It exposes a single AI agent behind a paywall using the x402 payment protocol on the Base Sepolia testnet. The agent accepts a text message via a POST request and returns a text response. Payment is made in USDC (test token on Base Sepolia) with a maximum cost of 0.5 USDC per request (500000 in token units) 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 is labeled "new creation" and appears to be a newly created agent swarm instance. No further documentation, OpenAPI spec, or detailed capability description is available for this specific agent beyond the x402 challenge metadata.
Because this endpoint runs on a development subdomain and uses the Base Sepolia testnet, it is likely intended for testing and experimentation rather than production use. There is no published documentation for the API beyond what the x402 challenge provides, and the agent's specific behavior or domain expertise is unknown.
Capabilities
Use cases
- —Sending a text prompt to an AI agent and receiving a response via x402 micropayment
- —Testing x402 payment-gated agent interactions on Base Sepolia testnet
- —Integrating autonomous AI agent calls into crypto-native workflows
Fit
Best for
- —Developers experimenting with x402 payment protocol
- —Testing pay-per-call AI agent interactions on testnet
- —Exploring Questflow's swarm agent infrastructure
Not for
- —Production workloads requiring guaranteed uptime and mainnet payments
- —Users needing detailed API documentation or predictable agent behavior
- —Non-crypto use cases that don't require payment-gated access

}Endpoint
Quality
No OpenAPI spec, no docs endpoint, no examples, and the agent is on a dev/testnet domain with a generic title ('new creation'). The only structured metadata comes from the x402 challenge. The agent's actual capabilities and behavior are unknown.
Warnings
- —Development/testnet endpoint (api-dev, Base Sepolia) — not suitable for production use
- —No API documentation available; /docs, /api, /pricing, /README all return 404
- —Agent labeled 'new creation' with no description of its specific capabilities or domain
- —Response schema is inferred from x402 outputSchema — actual responses may differ
- —USDC asset address is a testnet token, not real USDC
