Delx Commerce Circuit Breaker State
x402
Delx Commerce Circuit Breaker State is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Computes the current state (open/half-open/closed) of a circuit breaker given failure counts and timing parameters, returning whether requests should be allowed through.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the computed circuit breaker state string ('open', 'half-open', or 'closed'), a boolean allow_request indicating whether the caller should proceed, and an echo of the input parameters (open_after, cooldown_ms, open_for_ms, consecutive_failures) along with the schema identifier 'delx/util-circuit-breaker-state/v1'.
Example use cases
Blocking requests to a failing dependency
“My order service has hit 8 consecutive failures and my circuit breaker threshold is 5. The breaker has been open for 300ms and my cooldown is 2000ms. Tell me whether I should block the next request or let it through.”
Checking half-open retry eligibility
“My circuit breaker opened after 3 failures and has been open for 5000ms — the cooldown is 3000ms. Is the breaker now in half-open state and can I try a test request?”
Validating resilience config in agent workflow
“Before I route traffic to my inventory service, check the circuit breaker state: 0 consecutive failures so far, breaker opens after 10, cooldown is 500ms, and it hasn't been open at all. Is the circuit closed and safe to send requests?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/circuit-breaker-state?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or automated workflow needs a stateless, pay-per-call circuit breaker state evaluation without running its own state machine. It is ideal for agents that track failure counters externally and need a canonical computation of open/half-open/closed state — especially in multi-agent or serverless environments where maintaining in-process circuit breaker libraries is impractical. Prefer it over self-implemented logic when you want a verifiable, schema-versioned result billed per computation via USDC on Base or Solana.
Side effects
- Missing or non-numeric input fields may cause a 400 validation error
- Negative values for timing or failure counts may produce unexpected state results
- Network or payment failure (x402 USDC payment not confirmed) will block the response
- If open_for_ms and cooldown_ms are both zero, edge-case state transitions may be ambiguous
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. |
