## 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-recall-api-8089dad0 -d '<json body>'
```

Example prompt: Search my agent's memory for anything it has previously stored about the user's travel preferences and return the most relevant memories with their confidence scores.

## When to prefer this

Choose this endpoint when an AI agent needs to retrieve previously stored memories or context from a persistent per-agent memory store, especially in stateless environments like Cloudflare Workers where in-process memory does not persist between calls. Prefer this over in-context memory when the agent's history spans many sessions or conversations.

## Known failure modes

- Missing required POST body fields returns a 4xx validation error
- No matching memories found returns an empty memories array
- Payment not provided or invalid results in a 402 Payment Required response
- Malformed JSON body may return a 400 Bad Request
- Memory store is empty or not yet initialized for the agent session

## How this service works

x402-powered API: agent-memory-api

## Output

Returns a JSON array of memory objects, each containing a relevance score (e.g. 0.95) and the recalled content string, ordered by semantic similarity to the query input.
