## 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 gadgethumans-agent-memory-store-89cef099
```

Example prompt: Remember that my preferred language is Spanish — store that in memory under the key 'user_language' with the value 'Spanish'.

## When to prefer this

Choose this endpoint when an AI agent needs lightweight, persistent key-value memory to store state, preferences, or intermediate results between sessions or workflow steps. It is ideal for agents that need to remember simple string data without managing a full database. Best suited for low-frequency writes where $0.002 per call is acceptable and no API key setup is desired.

## Known failure modes

- Missing or empty 'key' parameter returns an error
- Missing or empty 'value' parameter returns an error
- Network timeout if the service is unavailable
- Payment failure (HTTP 402) if USDC balance is insufficient for the $0.002 per call fee
- Large or malformed values may be rejected
