Delx Seeded Partition
x402
Delx Seeded Partition is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Deterministically assigns a list of items to named partitions using a seed string for reproducible, governed distribution.

How this service works
Seeded Partition: Seeded Partition assigns each caller item reproducibly into a named partition from bounded caller-supplied values without an external provider. Call Seeded Partition 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 Partition as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, m…
Output
Returns a JSON object with a list of partition names, an array of item-to-partition assignment objects (each with item and partition fields), plus an evidence block containing the input SHA-256 hash, a flag confirming no data was retained, and a count of zero external calls made. The schema version and operation name are also included for auditability.
Example use cases
Reproducible task routing for agent fleet
“I have 12 crawl tasks and 3 agent workers named alpha, beta, and gamma — use the seed 'sprint-42' to deterministically assign each task to a worker so the same seed always gives the same routing.”
Dataset sharding for parallel processing
“Split these 50 dataset file paths across 4 partitions called shard-0, shard-1, shard-2, and shard-3 using the seed 'etl-batch-2024' so I can process them in parallel reproducibly.”
A/B experiment group assignment
“Assign each of these 20 user IDs to either the 'control' or 'treatment' partition using the seed 'experiment-v3' so the assignment stays consistent every time I run it.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-partitionWhen to prefer
Choose this endpoint when you need deterministic, reproducible item-to-partition assignment governed by a seed — ideal for agent task routing, dataset sharding, or A/B group assignment where auditability (via SHA-256 evidence) and zero data retention matter. Prefer it over random assignment when replay reproducibility is required, and over custom hashing logic when you want a governed, verifiable micro-service with an audit trail.
Side effects
- Missing or empty items array returns a validation error
- Partitions array is empty causing no valid assignments
- Items or partitions exceeding 256 elements return a 4xx payload ceiling error
- Seed string exceeding 8192 characters causes schema rejection
- Malformed JSON body returns a parsing error
- Network timeout on the POST request with no partial result
