## 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 aegis-pro-subscription-x402-agent-economy-trust-layer-1fc584f2
```

Example prompt: Sign me up for the Aegis Pro subscription so my agent can discover and trust-check agent-payable x402 services using real-purchase-backed trust scores.

## When to prefer this

Choose this endpoint when an agent needs to establish authenticated, Pro-tier access to the Aegis trust registry for the x402 agent economy — specifically when the agent requires trust-score-backed service discovery, routing, and procurement capabilities beyond what a free tier offers. Prefer this over manual service lists or unverified x402 directories when payment safety and provenance matter.

## Known failure modes

- Payment failure: insufficient USDC balance causes 402 response with payment required details
- Already subscribed: duplicate subscription attempt may return conflict or existing token
- Invalid properties payload: malformed input schema causes 400 bad request
- Expired session: token returned may not be accepted if clock skew is significant
- Network timeout: 20 USDC charge may or may not have processed if response is lost

## How this service works
