## 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 inter-agent-policy-evaluator-9382d2be -d '<json body>'
```

Example prompt: Before letting the data-processing agent hand off to the reporting agent, check whether their policies are compatible — specifically look for any conflicts around data access permissions or cost constraints.

## When to prefer this

Choose this endpoint when orchestrating multi-agent systems where two or more agents have explicit declared policies and you need to verify those policies do not conflict before allowing agent-to-agent communication, data sharing, or task handoff. Prefer this over manual policy review when policies are machine-readable and automated pre-flight safety checks are needed at runtime.

## Known failure modes

- Missing or malformed policy objects result in validation error
- Ambiguous or underspecified policies may yield inconclusive compatibility verdict
- Policies in unsupported or non-standard formats may not be parsed correctly
- Rate limiting or payment failure at $0.003 USDC per call threshold
- Conflicting policies with no clear resolution path return conflict without recommended fix

## How this service works

Detect compatibility or conflict between agent policies

## Output

Returns a compatibility or conflict verdict between the submitted agent policies, including identification of conflicting rules, severity of conflicts, and whether the policies can safely coexist or require resolution before agent interaction is permitted.
