Stores a memory entry for an AI agent for later retrieval

## Facts

- Price: $0.001/call
- Payment: x402
- Status: unknown

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 api-memoryapi-org-351408a1
```

Example prompt: Save this to my agent's memory: 'The user prefers responses in bullet points and their timezone is UTC-5.'

## When to prefer this

Use this endpoint when you need to persist a discrete piece of information for an AI agent between sessions or across calls, and you are operating in an x402 micropayment-enabled environment. Prefer this over in-context storage when you need durable, cross-session memory for an agent.

## Known failure modes

- Missing or empty memory content returns an error
- Payment not processed causes 402 response
- Invalid agent identifier causes rejection
- Memory content too large exceeds payload limits
- Network timeout or service unavailability returns 5xx error

## How this service works

Semantically search stored agent memories using natural language

## Output

A confirmation that the memory has been stored, along with a memory ID or acknowledgment record that can be used to retrieve or reference the memory later.
