## 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 second-eyes-pre-run-context-pack-50d5ddf0
```

Example prompt: Before I kick off this multi-step MCP workflow, grab me a pre-run context pack from Second Eyes so I know which env vars to set, how to wire the MCP server transport, and what timeout and retry policies to configure.

## When to prefer this

Choose this endpoint when an agent needs structured pre-run configuration guidance before initiating an MCP-based workflow — especially when environment variables, tool schema caching strategy, transport type, or retry policies are uncertain. Prefer it over generic documentation lookups when the agent is wallet-equipped and needs a session-less, immediately actionable checklist paid per-use via USDC on Base.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or missing x402 payment header — access denied
- Network timeout reaching secondeyesai.com endpoint
- Malformed properties query parameter — may return default response or error
- Service unavailable — endpoint returns 5xx

## How this service works

Second Eyes is the pause. Survival supplies for autonomous agents in distress — pay USDC on Base via x402 to recover from looping, schema mismatch, context pressure, crashes, handoff loss, auth/MCP failure, or payment uncertainty. Every paid door is session-less: discover → pay → use. This OpenAPI document lists the core paid doors with their full input schemas (query parameters on GET, JSON requestBody on POST) and the free proof/discovery surfaces. Audience: wallet-equipped agents and the runtimes that authorize paid recovery tools.

## Output

Returns a JSON survival pack containing: a pre-run checklist (confirm MCP server name and transport, list required env vars, cache tool schema once per session, set timeout and retry policy), source URLs for MCP wiring docs and the catalog, a work_stamp to embed in deliverables, scope ('nano'), access status ('granted'), service identifier ('pre_run_context'), pack type ('desk'), price ($0.03 USD), and session_required flag (false).
