Delx Seeded Range Sequence
x402
Delx Seeded Range Sequence 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).
Generates a deterministic sequence of random integers within a specified range using a seed string, returning the same values every time for the same inputs.

How this service works
Seeded Range Sequence: Seeded Range Sequence generates unique reproducible integers from a bounded range from bounded caller-supplied values without an external provider. Call Seeded Range Sequence 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 Range Sequence as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-…
Output
Returns a JSON object containing a 'values' array of integers within the specified range, an operation name, a status field ('pass'), and an evidence block confirming no data was retained, no external calls were made, and an SHA-256 hash of the input for auditability.
Example use cases
Reproducible test data generation
“I need 10 random integers between 0 and 255 that are always the same when I use the seed 'test-suite-v3' — can you generate that sequence for me?”
Deterministic lottery number draw
“Use the seed 'weekly-draw-2024-06-10' to generate 6 numbers between 1 and 49 — I need the draw to be reproducible if anyone challenges it.”
Seeded random sampling for A/B assignment
“Give me a sequence of 20 integers between 1 and 2 using the seed 'experiment-cohort-7' so I can assign users to groups the same way every time.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-range-sequenceWhen to prefer
Choose this endpoint when you need a deterministic, reproducible sequence of random integers — i.e., the same seed must always yield the same output. Prefer it over true random number generation when auditability, reproducibility, or consistent test fixtures are required. It is not suitable for cryptographic randomness or security-sensitive applications.
Side effects
- Seed exceeds 8192 character limit — request rejected
- Count or minimum/maximum values are missing or non-integer — schema validation error
- Minimum greater than maximum — likely returns error or undefined behavior
- Payment failure (x402) — endpoint returns 402 before computation
- Network timeout — no result returned
