## 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 54ch10-paste-retrieve-f163074a
```

Example prompt: Can you retrieve the security brief I stored earlier with paste ID abc123xyz from 54ch10 and show me what it contains?

## When to prefer this

Use this endpoint when an agent has previously written a security brief to 54ch10's paste service and needs to retrieve it for handoff to another agent or downstream step. This is specifically for the read/retrieve side of the ephemeral paste workflow — prefer this when you have a paste ID and need to fetch its content, not when you want to run a new security analysis.

## Known failure modes

- Paste ID not found or expired — returns error if TTL has elapsed or ID is invalid
- Missing required 'id' query parameter — returns validation error
- Paste already consumed or deleted — ephemeral pastes may be single-use
- Rate limiting or payment failure — x402 payment required per call

## How this service works

54ch10: pre-interact URL check. Paste a link, get brief + domain + page. Taste /v1/open/free. 80 calls for $1. Wire in 30s. Analytics-only tooling. Not financial advice.

## Output

Returns a JSON object containing the paste ID, an ok status flag, the stored content, the TTL in seconds indicating how long until expiry, the retrieve URL, a tier label, a note clarifying this is ephemeral agent handoff only and not a vault, and a disclaimer that this is informational tooling only and not financial advice.
