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.
Example use cases
Pre-tool-call context safety check
“Before I run the next expensive search tool, tell me if my context pressure is too high and whether I need to compact my context window first.”
Recovering a looping agent
“My agent keeps looping and I think it's because the context is overloaded — can you assess the pressure level and tell me exactly what to do to recover it?”
Autonomous agent runtime guardrail
“My agent runtime needs to know if the current context usage is in a danger zone — give me a pressure verdict and the recommended next step before it makes another API call.”
Technical details
Endpoint
POSThttps://secondeyesai.com/api/bar/x402/context-pressureWhen to prefer
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.
Side effects
- 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
