Pay-per-message AI agent endpoint on Questflow's swarm network via x402 micropayments.
What it does
This x402-enabled endpoint exposes a Questflow "swarm" agent that accepts a text message and returns an AI-generated response. Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e). The maximum amount required per request is 500,000 units (likely 0.50 USDC given 6-decimal USDC), with a timeout of up to 1,200 seconds.
Questflow is a platform focused on autonomous AI "clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) for trading, signal generation, and revenue earning. This particular endpoint is labeled "Personal use" and appears to be a general-purpose conversational agent within the Questflow swarm infrastructure. The input/output schema is simple: POST a JSON body with an `input` string field and receive a `response` string field.
Documentation is extremely sparse. There is no OpenAPI spec, no dedicated docs page, and no detailed description of what the agent actually does beyond the generic "Personal use" label. The endpoint is on a dev/staging domain (api-dev.intra-tls2.dctx.link), and the payment network is Base Sepolia (a testnet), suggesting this is not yet a production service. Prospective users should treat this as experimental.
Capabilities
Use cases

}Endpoint
Quality
No OpenAPI spec, no docs, no examples, dev/testnet domain, and the endpoint description is just 'Personal use'. The only concrete information comes from the x402 challenge payload. The response example is entirely inferred.
Warnings
- —Endpoint is on a dev/staging domain (api-dev.intra-tls2.dctx.link) — likely not production-ready
- —Payment network is Base Sepolia (testnet), not mainnet
- —No API documentation, OpenAPI spec, or usage examples available
- —The 'Personal use' label provides no meaningful description of agent capabilities
- —Response example is fabricated for illustration; actual behavior is unknown
