# SML Memory Graph Recall

> SML Memory Graph Recall is a paid API for AI agents from scriptmasterlabs.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Retrieves stored memory entries for a specific AI agent namespace by keyword query, tags, or limit, returning structured knowledge graph results.

## Facts

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 sml-memory-graph-recall-135026ff
```

Example prompt: Search the SML Memory Graph for agent 'agent-42' and recall up to 10 memories tagged 'project-alpha' that mention 'deadline'.

## When to prefer this

Choose this endpoint when an AI agent needs to retrieve previously stored contextual knowledge from a persistent memory graph, especially when filtering by agent namespace, keywords, or tags. Prefer this over generic database queries when the use case is specifically agent memory recall within the SML ecosystem.

## Known failure modes

- Missing required agent_id parameter returns an error
- No matching memories found returns empty results
- Payment not accepted results in no data delivery
- Invalid query syntax may return empty or partial results
- Rate limiting or service unavailability returns a non-200 response

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

Returns a JSON object containing recalled memory entries or knowledge graph nodes for the specified agent namespace, filtered by query, tags, and limit as provided. Actual live response values are returned after successful payment acceptance.
