Questflow SANTA agent: chat-based on-chain chief-of-staff for crypto teams via x402 micropayment
What it does
Questflow's SANTA (Secure Agent Network for Trustless Action) is an AI agent endpoint accessible via the x402 payment protocol on Base Sepolia. It accepts a text message via POST and returns a text response from the agent. The endpoint is designed to serve as an on-chain assistant pre-loaded with workflows for rewards, analytics, community communications, and feedback loops for crypto teams.
The endpoint charges up to 0.50 USDC (maxAmountRequired of 500000 in 6-decimal USDC units) per request, paid to address 0xb7e3Db5c9586A22DD13D05d237E419374B93B498 on the Base Sepolia testnet. The x402 challenge specifies a maximum timeout of 1200 seconds. The input schema is simple: a single required string field called "input" containing your message to the agent, and the output is a single string field called "response".
Questflow is a broader platform focused on AI "Clones" that aggregate on-chain markets (Polymarket, Pump.fun, OKX, Opinion Labs) for autonomous trading and alpha discovery. SANTA appears to be one specific agent swarm exposed through their x402-compatible API. Note that this endpoint runs on Base Sepolia (a testnet), so it is likely in a development or preview stage rather than production. No OpenAPI spec or dedicated documentation was found for this endpoint.

Quality
The endpoint is live (402 challenge confirmed) with a clear input/output schema, but there is no OpenAPI spec, no dedicated documentation, and the endpoint runs on a testnet (Base Sepolia). The description is largely inferred from the x402 challenge metadata and the existing listing description. The response example is fabricated as a plausible placeholder since no actual response was captured.
Warnings
- —Endpoint runs on Base Sepolia testnet — not production mainnet
- —No OpenAPI spec or dedicated API documentation found
- —No actual response example available; output schema inferred from x402 challenge
- —The example response JSON is illustrative only, not captured from a real call
- —The /docs, /api, /pricing, and /README paths all return 404
