## 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 whitemagic-hosted-recall-93f74249 -d '<json body>'
```

Example prompt: Use WhiteMagic's hosted recall tool to fetch the information I saved about my project requirements earlier.

## When to prefer this

Choose this endpoint when you need a single, pay-per-use hosted recall operation via the WhiteMagic MCP service without managing your own memory infrastructure. It is ideal for agents that occasionally need to retrieve stored context or memories and want a lightweight, hosted solution billed at $0.01 USDC per call. Prefer alternatives if you need bulk recall operations or free in-session memory.

## Known failure modes

- No matching memory found for the query — returns empty or not-found response
- Invalid or missing tool call parameters — returns error indicating bad input
- Payment failure (0.01 USDC not available or x402 auth issue) — returns 402 Payment Required
- Endpoint unreachable or server error — returns 5xx response
- Recall key/query too vague — may return unrelated or null result

## How this service works

WhiteMagic hosted recall: read-only hybrid memory search (BM25 + vector + associative) over a curated public corpus for agent continuity. Call when an agent needs durable context from prior sessions or the public knowledge store. Keyless discovery (initialize/tools/list) is free; free evaluation keys and a daily no-key trial are available. One paid tool call per payment.

## Output

The agent receives the recalled content or data previously stored, returned as the tool call response from the WhiteMagic MCP endpoint — typically a structured result containing the remembered information or a confirmation that nothing was found for that query.
