Delx Seeded Jitter Ms
x402
Delx Seeded Jitter Ms is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-20).
Computes a deterministic, seed-based jitter value in milliseconds from a base delay and jitter fraction, returning both the total and jitter components.

How this service works
Seeded Jitter Ms: Seeded Jitter Ms adds reproducible bounded jitter to a base delay from bounded caller-supplied values without an external provider. Call Seeded Jitter Ms 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 Jitter Ms as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only e…
Output
Returns a JSON object containing delay_ms (the total delay including jitter), jitter_ms (the jitter component alone, which may be negative), the operation name, a status field, and an evidence block confirming no data retention and zero external calls, plus the SHA-256 hash of the input.
Example use cases
Retry backoff for distributed agents
“I'm building a fleet of agents that all retry a shared API endpoint. Use the seed 'fleet-node-7' with a base delay of 500 ms and jitter fraction 0.3 to give me a deterministic jitter offset so each agent waits a slightly different amount without colliding.”
Reproducible test timing for CI pipelines
“For my CI test suite, I need reproducible timing delays between steps. Compute a seeded jitter using seed 'ci-run-2024', base 2000 ms, and jitter fraction 0.1 so every test run produces the same delay values.”
Thundering herd prevention for scheduled crawlers
“My 50 web crawlers all wake up at the same time and slam the target server. Can you generate a deterministic jitter for crawler 'crawler-shard-12' with a base interval of 3000 ms and a jitter fraction of 0.25 so it wakes up at a consistently staggered time?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-jitter-ms?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, reproducible jitter values driven by a seed string — ideal for distributed agent coordination, reproducible test suites, or consistent backoff schedules where random-per-call jitter would break reproducibility. Prefer this over local random number generation when you need auditability (input hash provided) and stateless, in-memory computation with no data retention guarantees.
Side effects
- Missing required seed field returns validation error
- jitter_fraction outside expected range may produce unexpected results
- base_ms of zero or negative may produce zero or negative delay_ms
- Malformed JSON body returns 400-level error
- Network timeout if upstream service is temporarily unavailable
