How this service works
Build a bounded exponential retry delay schedule with a hard delay cap — call when configuring exponential backoff before calling a flaky dependency. 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…
Output
Returns a deterministic JSON object containing the computed delay schedule — an ordered list of delay values in milliseconds for each retry attempt up to max_attempts, each capped at max_delay_ms. The output is machine-readable and stateless, with no server-side retention.
Example use cases
Backoff plan before flaky third-party call
“Before I call that unreliable payment API, generate me an exponential retry schedule: start at 500ms, double each time, cap at 60000ms, and plan for up to 10 attempts.”
Agent workflow retry budget configuration
“I'm composing a multi-step agent job and need a retry delay schedule — base delay 100ms, factor of 3, hard ceiling of 15000ms, and no more than 6 retries.”
Circuit breaker delay ladder for microservice
“Give me a deterministic backoff ladder for my microservice: initial delay 250ms, exponential factor 2, max single delay 20000ms, and schedule 12 attempts total.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/retry-budget-planWhen to prefer
Choose this endpoint when you need a deterministic, locally-computed, stateless exponential backoff schedule with a hard delay ceiling and no external dependencies. Ideal for agent orchestration pipelines that require reproducible retry budgets before side-effecting operations, or when you want a cheap ($0.003 USDC), zero-latency computation without storing any inputs upstream.
Side effects
- Invalid factor value (e.g. negative or zero) returns a 4xx validation error
- max_attempts outside the 1–20 range returns a validation error
- Missing required fields returns a 400 bad request
- Payment not included or insufficient USDC returns a 402 Payment Required response
Input
