Delx Seeded Random Float
x402
Delx Seeded Random Float 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 one or more deterministic pseudo-random floats within a specified range from a given seed string.

How this service works
Seeded Random Float: Seeded Random Float returns reproducible floats inside caller bounds from bounded caller-supplied values without an external provider. Call Seeded Random Float 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 Random Float as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, m…
Output
Returns a JSON object containing an array of pseudo-random float values deterministically derived from the provided seed, along with the minimum and maximum bounds used, a status indicator, and an evidence block confirming no external calls were made and no input was retained.
Example use cases
Reproducible A/B test assignment
“I need to randomly assign users to groups A or B in a reproducible way — use the seed 'experiment-2024' to generate 10 floats between 0 and 1 so I can threshold them at 0.5.”
Deterministic game loot drop
“For my game level 'dungeon-floor-3', generate 3 random floats between 0.1 and 0.9 using that string as the seed so the loot drops are always the same for that level.”
Seeded random sampling for ML
“I need to reproducibly sample from a dataset — give me 20 random floats between 0 and 100 seeded with 'ml-split-seed-7' so I get the same sample every time I run this.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-random-floatWhen to prefer
Choose this endpoint when you need deterministic, reproducible pseudo-random floats — i.e., the same seed must always produce the same sequence. Prefer it over true random endpoints when you need replay-ability, auditability, or consistent test fixtures. It is ideal for agent workflows where randomness must be traceable and verifiable, and where you need to confirm no external state was modified (evidenced by the `retained:false` and `external_calls:0` fields in the response).
Side effects
- Invalid or missing seed parameter returns an error
- Count value of zero or negative integer may return an empty array or error
- Minimum value greater than maximum value may result in a validation error
- Excessively long seed string beyond 8192 characters will be rejected
- Non-numeric minimum or maximum values will cause a schema validation failure
