# Second Eyes Context Pressure Check

> Second Eyes Context Pressure Check is a paid API for AI agents from secondeyesai.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-13).

Analyzes an agent's current context pressure level and returns a verdict on whether to stop, compact, or continue, plus actionable recovery instructions.

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-context-pressure-check-312e571d -d '<json body>'
```

Example prompt: I'm about to make another tool call but I think my context is nearly full — can you check my context pressure and tell me whether I should stop and compact first, or if it's safe to continue?

## When to prefer this

Use this endpoint when an autonomous agent is approaching its context window limit and needs a structured, paid diagnostic verdict before making the next expensive tool call. Prefer this over ad-hoc compaction logic when you want a confidence-scored recommendation with an explicit escalation path and a pointer to the next recovery step.

## Known failure modes

- Payment not received — endpoint returns 402 and does not process request
- Malformed or missing request body — may return 400 with schema error
- Insufficient context properties provided — verdict may be low-confidence or generic
- Network timeout during payment verification — agent must retry
- USDC balance insufficient on Base — payment fails before processing

## 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 with: a stop/continue verdict, a pressure band label (e.g. 'stop_and_compact'), the fraction of context used, a confidence score, specific compaction instructions, what context to preserve vs drop, the URL of the recommended next recovery tool, and an escalation condition if compaction is insufficient.
