# NOVA Agent Delegation Router

> NOVA Agent Delegation Router is a paid API for AI agents from nova-demand-worker.vercel.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Routes an agent-to-agent (a2a) delegation payload through the NOVA x402 pay-per-call infrastructure on Base with USDC, returning acceptance and routing confirmation.

## 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 nova-agent-delegation-router-d2ea209c -d '<json body>'
```

Example prompt: Route this task payload through NOVA's agent delegation system — use x402 on Base with USDC — and confirm whether the delegation was accepted and routed.

## When to prefer this

Choose this endpoint when you need to delegate tasks between AI agents programmatically via a pay-per-call micropayment model using x402 on Base with USDC, particularly when agent-to-agent (a2a) routing confirmation is required. Prefer it over generic HTTP relays when you need built-in payment gating and routing status feedback in a single call.

## Known failure modes

- Payment failure: x402 payment not included or insufficient USDC balance causes rejection
- Invalid payload: malformed or missing 'payload' object results in routing failure
- Network error: Vercel worker unavailability causes 5xx response
- Delegation rejection: downstream agent refuses the task, returning accepted:false
- Routing failure: routed:false returned if no eligible agent target found

## How this service works

Machine-facing pay-per-call utility services using x402 on Base with USDC.

## Output
