How this service works
Derive closed, open, or half-open circuit state from failure and cooldown inputs — call when deciding closed/open/half-open from failure counters. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of…
Output
Returns a deterministic JSON object indicating the current circuit breaker state — one of 'closed', 'open', or 'half-open' — based on whether consecutive failures have met the open threshold and whether the cooldown period has elapsed since the breaker opened.
Example use cases
Guard downstream API call in agent
“Before calling the payment service, check the circuit breaker state — we've had 8 consecutive failures, the breaker opens after 5, cooldown is 60000ms, and it's been open for 10000ms. Should I proceed or hold back?”
Retry decision after cooldown elapsed
“Our database dependency tripped after 3 consecutive failures with an open_after threshold of 3. The cooldown is 15000ms and it's been open for 20000ms. Is the circuit breaker half-open now so I can send a test request?”
Healthy dependency check before workflow step
“I want to confirm the circuit breaker is still closed before kicking off the next workflow step — we've had 0 consecutive failures, open_after is 5, cooldown is 10000ms, and open_for_ms is 0.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/circuit-breaker-stateWhen to prefer
Choose this endpoint when you need a stateless, deterministic circuit breaker state evaluation with no server-side state management — ideal for agent workflows that track failure counters locally and need a reliable, cheap ($0.003 USDC) computation step before deciding whether to invoke a downstream dependency. Prefer this over building circuit breaker logic inline when you want a consistent, auditable machine-readable JSON result without managing state on a remote server.
Side effects
- Missing required fields (e.g. consecutive_failures or open_after) may return a validation error
- Negative or non-numeric values for timing/count fields may cause an error response
- If cooldown_ms is 0 and breaker is open, half-open logic may behave unexpectedly
- Payment failure via x402 returns 402 before computation occurs
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| open_after | number | Failures required before the breaker opens. |
| cooldown_ms | number | Milliseconds the breaker stays open before half-open. |
| open_for_ms | number | How long the breaker has already been open. |
| consecutive_failures | number | Current consecutive failure count for the dependency. |
