How this service works
Seeded Backoff Schedule: Seeded Backoff Schedule builds a reproducible jittered exponential backoff schedule from bounded caller-supplied values without an external provider. Call Seeded Backoff Schedule when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Backoff Schedule as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base…
Output
Returns a JSON object with the total combined delay in milliseconds and an array of individual per-attempt delay values in milliseconds, along with operation metadata including input hash and a confirmation that no data was retained externally.
Example use cases
Rate-limited API retry planning
“I'm hitting a rate-limited third-party API and need a retry schedule — use seed 'rate-limit-run-7', factor 2.5, base 300ms, 6 attempts, and jitter 0.15 so my agents don't all collide.”
Reproducible distributed agent retries
“My fleet of agents all need to use the same deterministic retry timing for consistency — compute a backoff schedule with seed 'fleet-sync-99', factor 2, base 500ms, 4 attempts, and jitter fraction 0.2.”
Debugging slow retry accumulation
“I think my retry delays are adding up too fast — can you calculate the total wait time using seed 'debug-run-1', factor 3, base 100ms, 5 attempts, and jitter 0.05 so I can see each delay?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-backoff-scheduleWhen to prefer
Choose this endpoint when you need a deterministic, reproducible backoff schedule seeded from a known string — particularly useful for distributed agent fleets that must share the same retry timing without coordination, or when you need to audit or replay the exact same delay sequence. Prefer it over client-side implementations when you want a managed, stateless computation with zero data retention and a verifiable input hash.
Side effects
- Invalid seed type (non-string) causes validation error
- Negative or zero base_ms returns error or undefined behavior
- Attempts value of 0 returns empty delays array
- Factor <= 1 may produce flat or decreasing schedule instead of exponential growth
- Jitter fraction outside [0,1] range may produce unexpected delay values
