Delx Seeded Token Generator
x402
Delx Seeded Token Generator is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).
Generates a deterministic token of specified length from a seed string and optional alphabet, computed in-memory without data retention.

How this service works
Seeded Token: Seeded Token builds a reproducible non-secret token from a caller alphabet from bounded caller-supplied values without an external provider. Call Seeded Token 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 Token as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only exec…
Output
Returns a JSON object containing the generated token string, a secret_safe boolean indicating whether the token is safe to treat as a secret, the operation name, a pass/fail status, and an evidence block showing that no data was retained and no external calls were made, along with the SHA-256 hash of the input for auditability.
Example use cases
Reproducible test fixture ID generation
“I need a deterministic 16-character token seeded with 'fixture-user-001' using only lowercase letters, so my integration tests always get the same ID no matter how many times I run them.”
Custom-alphabet coupon code from order seed
“Generate an 8-character coupon code from the seed 'order-2024-99872' using only uppercase letters A-Z — I need the same seed to always produce the same code for our records.”
Deterministic session token for replay testing
“Create a 20-character token from the seed 'replay-session-beta7' using alphanumeric characters only, so I can replay the exact same session identifier in my load tests.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-token?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible token derived from a known seed — especially in testing, fixture generation, or coupon/ID scenarios where the same input must always yield the same output. Prefer it over random token generators when reproducibility matters, and over full cryptographic libraries when you need a lightweight, no-retention, in-memory computation with an audit trail (input hash, zero external calls).
Side effects
- Seed or alphabet exceeds 8192 character limit — request rejected
- Invalid length value (non-integer or negative) — validation error
- Missing required seed parameter — bad request error
- Network timeout on the POST request — retry recommended
