Delx Commerce Seeded Range Sequence

x402

Delx Commerce Seeded Range Sequence is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Generates a reproducible, verifiably seeded sequence of random integers within a specified range, with cryptographic evidence of non-retention and no external calls.

How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

Output

Returns a JSON object containing an array of integers ('values') within the specified minimum/maximum range, a SHA-256 hash of the input for verifiability, evidence confirming no data was retained and no external calls were made, the operation name, and a schema identifier.

Example use cases

Reproducible random assignment for tasks

“I need to randomly assign 6 tasks to agents using the seed 'taskbatch-2024-06-01', with values between 0 and 5, so the assignment can be independently verified later.”

Seeded random loot drop in a game

“Using the seed 'player-session-XZ99', generate 10 random integers between 1 and 50 to determine loot drops — I need to be able to reproduce the same result if I use the same seed again.”

Verifiable random selection for a raffle

“Pick 5 random numbers between 1 and 200 using the seed 'raffle-july4-2024' so we can prove the draw was fair and the seed wasn't retained anywhere.”

When to prefer

Choose this endpoint when you need reproducible, verifiable random integer sequences with cryptographic evidence of non-retention and no external dependencies — ideal for agents that must prove fairness, auditability, or determinism. Prefer it over general-purpose random APIs when on-chain micropayment (USDC on Base/Solana) and verifiable delivery are requirements.

Side effects

Missing or invalid seed string — request fails or returns error
Count, minimum, or maximum values out of valid integer bounds — computation error returned
Minimum greater than or equal to maximum — invalid range error
Payment not completed via x402 — 402 Payment Required response
Malformed JSON input — 400 Bad Request
