Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vaaya-mem0-add-memory-d9ad57cf -d '<json body>'
```

Example prompt: Save this to memory for user 'user_abc123': the assistant said 'Your next meeting is at 3pm on Friday' and the user replied 'Got it, thanks' — infer memory from the conversation.

## When to prefer this

Use this endpoint when your AI agent needs to persist memory entries for individual users in a mem0-compatible store without managing your own API keys or mem0 account — ideal for multi-session agents that need to remember user context, preferences, or conversation history across interactions, especially within the Vaaya agent infrastructure.

## Known failure modes

- Missing required 'user_id' or 'messages' fields returns a validation error
- Empty messages array (minItems:1 violated) causes request rejection
- Invalid role or missing content in a message object triggers a schema error
- Network or upstream mem0 service failure returns a 5xx error
- Insufficient payment (x402) causes the request to be rejected before processing

## How this service works

Give an AI agent a credit account. Set a limit and a spending policy, and the agent makes approved, metered purchases from providers that accept Vaaya.

## Output

Returns a confirmation object indicating the memory entry was successfully stored in mem0 for the given user, potentially including a memory ID or structured acknowledgment of what was persisted.
