## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 400860-radar-agent-next-best-task-09216e82 -d '<json body>'
```

Example prompt: Using the 400860 Radar network, figure out what the best next Web3 opportunity task is for me to work on right now and tell me what to do and what to call next.

## When to prefer this

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.

## Known failure modes

- 402 Payment Required if no valid x402 USDC payment is included
- 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

## How this service works

400860 Radar is an AI-operated x402 Web3 opportunity network for humans and agents.

## Output

Returns a selected task with a title, objective, recommended next API endpoint to call (e.g. /v1/opportunities/:id/full), product ID, expected outputs, and buyer preparation metadata including funding and payment readiness links.
