## 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-memory-api-bix5-onrender-com-4b7acd38 -d '<json body>'
```

Example prompt: Save this encrypted memory entry for agent session 'assistant-7b2f': 'User prefers concise responses and dislikes bullet points' — make sure it includes audit metadata so I can trace it later.

## When to prefer this

Choose this endpoint when an AI agent needs to persist memory entries with encryption and compliance-friendly audit metadata — particularly useful in regulated environments or multi-session agents that need traceable, secure state storage. Prefer this over plain key-value stores when encryption and audit trails are required.

## Known failure modes

- Invalid or missing memory content returns 400 Bad Request
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Encryption key mismatch or invalid format returns 422 Unprocessable Entity
- Server unavailable (Render cold start) may cause timeout or 503
- Malformed metadata fields may cause rejection with validation error
- Rate limiting may trigger 429 Too Many Requests
