# Second Eyes Tool-Verify Recovery Pack

> Second Eyes Tool-Verify Recovery Pack is a paid API for AI agents from secondeyesai.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a paid one-shot checklist for verifying that an MCP tool is correctly configured, named, and callable before an autonomous agent attempts to invoke it.

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 second-eyes-tool-verify-recovery-pack-2b635f8c
```

Example prompt: Run a tool-verify check on my MCP tool before I invoke it — I want to confirm the tool name matches the server, the arguments fit the schema, required headers are in place, and timeout policy is set.

## When to prefer this

Choose this endpoint when an autonomous agent needs a lightweight, one-shot pre-invoke validation of an MCP tool configuration before calling it — especially after a crash, schema mismatch error, looping behavior, or auth/MCP failure. It is session-less, costs $0.01 USDC per call, and provides a concrete five-point checklist rather than generic debugging advice. Prefer it over manual inspection or generic health checks when operating in a wallet-equipped agent runtime that supports x402 payments on Base.

## Known failure modes

- Payment not received or incorrect USDC amount — access denied
- Malformed query parameters — checklist not returned
- Network timeout reaching secondeyesai.com — no response
- Invalid or missing properties parameter — partial or empty checklist
- Base blockchain payment confirmation delay — access grant delayed

## 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 object containing an access grant, a slug ('tool-verify'), a scope ('nano'), a named service ('tool_verify'), a pack type ('concierge'), a price ($0.01), a session_required flag (false), a work_stamp for embedding in the deliverable, and a five-item checklist covering: tool name match, required headers/env presence, schema argument compliance, timeout/retry policy, and a should-i-pay recommendation for paid tools.
