Technical details
Endpoint
POSThttps://api.400860.xyz/v1/agent/next-best-taskWhen to prefer
Use this endpoint when an AI agent needs autonomous task selection within the 400860 Radar x402 Web3 opportunity network and lacks a predefined objective. Prefer this over manually browsing opportunities when you want the AI to prioritize and surface the single highest-value next action.
Side effects

- 400 Bad Request if required input fields (type, method, bodyType, body) are missing
- Empty or null task if no opportunities are currently available in the network
- Timeout if the AI task-selection engine is overloaded
- Invalid wallet address errors in buyer preparation links if address is malformed
