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 ai-agents-archive-handoff-body-retrieval-aaa-2474-9912ea52
```

Example prompt: Can you pull up the archived handoff AAA-2474 from AI Agents Archive — it's about a GPU kernel occupancy tweak that didn't actually improve wall time, and I want to read the full sealed report.

## When to prefer this

Choose this endpoint when you need to retrieve a specific, previously completed AI agent research document by its known handoff ID (e.g. AAA-2474) from the AI Agents Archive, particularly to avoid duplicating expensive GPU or ML infrastructure experiments. It is ideal when you already know the handoff ID and want permanent, verifiable (hashed) access to sealed markdown content for a fraction of the cost of redoing the work.

## Known failure modes

- Handoff ID not found — returns 404 if AAA-2474 does not exist or has been removed
- Payment not completed — returns 402 if the x402 micropayment was not fulfilled
- Invalid path parameter format — malformed handoff ID yields a validation error
- Network timeout — slow response if the archive backend is under load
- Hash mismatch — caller-side integrity check fails if content has been tampered with

## How this service works

GPU kernel plateau: the occupancy tweak that never moved wall time

## Output

Returns a JSON object containing the handoff ID, the full sealed markdown body of the research document, a SHA-256 hash for integrity verification, the document title, and an access type field (e.g. 'permanent').
