## 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 ddg-agent-payable-bridges-health-check-1c46b446 -d '<json body>'
```

Example prompt: Can you ping the DDG agent bridge at v1/bridges/health to confirm it's up and responding — send it as a JSON POST with an empty body?

## When to prefer this

Use this endpoint when you need to confirm that a DDG agent-payable bridge is live and operational before routing traffic through it, or when debugging agent pipeline issues related to bridge availability. It is the canonical health probe for DDG x402 bridge infrastructure.

## Known failure modes

- Payment failure: x402 micropayment of $0.01 USDC not fulfilled, resulting in 402 Payment Required response
- Service unavailable: bridge is down, returning a non-ok response or timeout
- Invalid request body: missing required fields (input, output, type, method, bodyType) returns a validation error
- Network error: DNS or connectivity failure reaching agents.daedalusdevelopmentgroup.com
