## 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 multi-sig-agent-authorizer-mcp-194c8104 -d '<json body>'

Example prompt: I need to authorize a high-stakes action in my agent pipeline — can you run it through the multi-sig authorizer with this approval payload so we can confirm enough agents have signed off before proceeding?

## When to prefer this

Choose this endpoint when your agentic workflow requires multi-party or multi-agent consensus before a sensitive action is executed, particularly when no single agent should have unilateral authority. Ideal for high-stakes decisions in swarm architectures, treasury operations, or permission escalation scenarios where a quorum-based approval model is needed.

## Known failure modes

- Insufficient signatures — quorum not yet reached, returns pending or rejected status
- Malformed data payload — input does not match expected authorization request format
- Expired authorization window — the request timestamp has lapsed
- Duplicate submission — same request already processed, returns cached result
- Service unavailability — upstream MCP endpoint unreachable
