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 agent-memory-api-recall-extract-b47a21c9 -d '<json body>'
```

Example prompt: Extract the key facts and decisions from this agent memory content: 'The user prefers USDC payments on Base, has previously asked about Japanese AI workflows, and wants daily summaries at 9am.' Use general extract type.

## When to prefer this

Choose this endpoint when you need to parse and structure raw AI agent memory content into discrete extractable items with confidence scores — especially in autonomous agent pipelines on Base/USDC that require auditable, encrypted memory recall with suggested next-step routing.

## Known failure modes

- Missing required 'content' field returns 422 validation error
- Content too large may cause timeout or processing error
- Invalid extract_type value may return empty or unexpected results
- Payment failure via x402 returns 402 Payment Required before processing
- Service unavailable on Render free tier (cold start delays)

## How this service works

Pay-per-request encrypted memory APIs for autonomous AI agents using x402. Store, recall, and audit AI agent memory with AES-256 encryption. Built for USDC/Base payments and Japanese AI agent workflows.

## Output

Returns an array of extracted items (strings), parallel confidence scores (floats 0-1) for each item, source location references within the content, and a next_recommended object suggesting a follow-up API call with its name, URL, reason, expected improvement, and price in USDC.
