# SML Memory Graph Store

> SML Memory Graph Store is a paid API for AI agents from scriptmasterlabs.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Stores structured memory entries (episodic, semantic, procedural, or custom) for a named agent namespace with provenance metadata, payable per call via x402.

## 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-store-adb2506b -d '<json body>'
```

Example prompt: Store an episodic memory for agent 'assistant-7' with content 'User prefers concise bullet-point summaries over prose' and tag it as 'preference' with a provenance confidence of 0.92.

## When to prefer this

Choose this endpoint when an AI agent needs to persist typed, tagged memory entries (episodic, semantic, procedural, or custom) in a structured graph store with provenance tracking, particularly in x402 pay-per-call architectures where per-use micropayments are acceptable and audit trails of confidence are important.

## Known failure modes

- Missing required 'provenance.confidence' field causes validation error
- Invalid 'type' value outside allowed enum (episodic, semantic, procedural, custom) may be rejected
- Payment not accepted or insufficient USDC balance causes 402 response
- Empty or missing 'content' field results in rejected store operation
- Unknown or malformed 'agent_id' namespace may cause routing failure

## 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 confirming storage in the SML Memory Graph, with the product name and any route-specific live values populated after successful accepted delivery via x402 payment.
