## 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 agent-wallet-credential-rotation-decision-procedure-833304a2
```

Example prompt: Give me the decision procedure for rotating my agent's wallet credentials — I need a plain-prose guide on when and how to trigger a key rotation safely.

## When to prefer this

Choose this endpoint when an autonomous agent needs on-demand, structured decision guidance specifically for wallet credential rotation — particularly in x402 micropayment architectures on Base where agents must manage their own signing keys. Prefer this over generic security docs when you need machine-readable prose a downstream agent can parse and act on immediately.

## Known failure modes

- HTTP 402 returned if payment not settled — must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Malformed or missing input object returns validation error
- Topic override may produce off-topic or lower-quality procedure if poorly specified
- Generation source may be 'deterministic' rather than 'llm', yielding a more generic response
- Service temporarily unavailable if K-2SO agent heartbeat has lapsed

## How this service works

Decision procedure for rotating per-rail agent wallet credentials without breaking in-flight x402 sessions. Covers when rotation is triggered (scheduled vs breach vs policy change), dual-key overlap windows so open payment sessions survive the cutover, sequencing of rotation across rails, revocation cascade order (session keys before master keys), and post-rotation reconciliation including re-attestation to the owner wallet. Inputs: credential age, exposure events, open session count, rail

## Output

A JSON object containing a plain-prose decision procedure (120+ words) advising an autonomous agent on when and how to rotate wallet credentials, along with metadata including the model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug. The 'brief' and 'procedure' fields hold the actionable guidance text.
