How this service works
Seeded Round Robin Start: Seeded Round Robin Start chooses a reproducible starting index for round-robin rotation from bounded caller-supplied values without an external provider. Call Seeded Round Robin Start 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 Round Robin Start as versioned deterministic JSON. Price: $0.001 USDC via x402…
Output
Returns a JSON object with a start_index (the computed zero-based position to begin the round-robin) and the member_count confirming the pool size, along with a schema identifier, pass/fail status, and an evidence block confirming no external calls were made and inputs were not retained.
Example use cases
Fair task distribution across agent workers
“I have 5 worker agents and want to rotate task assignment fairly — use the seed 'run-batch-001' across 5 members to find which agent should go first.”
Reproducible API replica selection
“I need to pick a starting replica in a round-robin for request routing — seed is 'user-session-abc123' and there are 12 replicas total, which index do we start at?”
Rotating shard assignment for analytics pipeline
“For our daily analytics job, use seed 'analytics-2024-06-01' with 8 shards and tell me the starting shard index so we distribute load consistently.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-round-robin-startWhen to prefer
Use this endpoint when you need a deterministic, reproducible starting position in a round-robin rotation derived from a seed string — such as distributing tasks, rotating API replicas, or seeding scheduler offsets. Prefer this over a random start when reproducibility across runs matters. It operates entirely in-memory with no data retention, making it safe for sensitive seed values.
Side effects
- Missing or empty seed results in validation error
- member_count of zero or negative triggers an error response
- Extremely long seed strings (near 8192 char limit) may be rejected
- Malformed JSON body returns 400-level error
- Non-integer member_count causes schema validation failure
