## 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 x402-agent-suite-budget-allocator-4b132573 -d '<json body>'
```

Example prompt: I have a fleet (fleetId: 'fleet-alpha-01') with 3 agents — agent-1 at priority 10 requesting 0.50 USDC with 1.00 USDC daily remaining, agent-2 at priority 5 requesting 0.30 USDC with 0.80 USDC daily remaining, and agent-3 at priority 8 requesting 0.20 USDC with 0.60 USDC daily remaining — and my pool has 0.75 USDC left; can you allocate the pool across those agents based on priority?

## When to prefer this

Use this endpoint when managing a multi-agent fleet that shares a common USDC spending pool and you need an automated, priority-weighted allocation decision rather than manually dividing funds. Ideal for agentic orchestration systems that need to enforce budget constraints across heterogeneous agents with different priorities and daily limits.

## Known failure modes

- Pool remaining USDC is zero or negative — allocation cannot proceed
- Agent list is empty — no agents to allocate to
- Requested amounts sum to zero — nothing to distribute
- Missing required agent fields (agentId, priority, requestedUsdc, dailyRemainingUsdc) — validation error
- Payment of $0.03 USDC fails or is not provided — 402 Payment Required
- Invalid fleetId format — request rejected

## How this service works

Allocates budgets across specified categories or goals with a paid run request.

## Output

Returns a budget allocation plan showing how much USDC each agent in the fleet should receive from the shared pool, factoring in their priority scores, requested amounts, and daily remaining limits.
