How this service works
loop-detect (session-less x402): you are stuck repeating the same tool call, error, or fix with no state change between attempts. Returns the quiet-room loop-break protocol — stop signals, the two-loop hypothesis test, and when to escalate to scope-check or cascade-break. One-shot, no session.
Output
Returns the quiet-room loop-break protocol: structured stop signals telling the agent when to halt, the two-loop hypothesis test to distinguish a real loop from a transient failure, and conditional escalation paths to scope-check or cascade-break procedures. Delivered as a one-shot, session-less response.
Example use cases
Example prompt
“I keep retrying the same tool call and getting the same error with no state change between attempts — can you run loop-detect to get the quiet-room loop-break protocol, including the two-loop hypothesis test and when I should escalate to a scope-check or cascade-break?”
Technical details
Endpoint
GEThttps://secondeyesai.com/api/bar/x402/loop-detectWhen to prefer
Choose this endpoint when an AI agent has detected it is stuck in a repetitive cycle — making the same tool call, encountering the same error, or applying the same fix with no observable state change between attempts — and needs a structured, authoritative protocol to diagnose and exit the loop without session state. Prefer this over generic retry logic when the agent needs explicit hypothesis-testing and escalation criteria.
Side effects
- Network error or timeout returning no protocol
- Malformed GET request returns 400 or schema validation error
- x402 payment not processed resulting in 402 with payment requirements
- Service unavailable returning 503 with no protocol delivered
