# Delx Commerce — Seeded Passphrase Words Generator

> Delx Commerce — Seeded Passphrase Words Generator 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 deterministic, human-readable passphrase (sequence of words) from a seed string and an optional word list, returning a reproducible label and array of words.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-seeded-passphrase-words-generator-9c372330 -d '<json body>'
```

Example prompt: Generate a seeded passphrase using the seed 'order-7842-abc' with 3 words from the list ['fox','stone','cloud','river','pine','ash'].

## When to prefer this

Choose this endpoint when you need deterministic, reproducible, human-readable word sequences derived from a seed — particularly when auditability and no-retention guarantees matter. Prefer it over local RNG-based passphrase generators when you want verifiable, pay-per-result computation with a cryptographic evidence trail (SHA-256 of input, zero external calls). Ideal for agents that need consistent labels across runs given the same seed without building or maintaining their own seeded RNG logic.

## Known failure modes

- Invalid seed type (non-string) causes schema validation error
- Count exceeding the word list length may produce fewer words or an error
- Excessively long seed (over 8192 chars) rejected by schema
- Empty word list with a non-zero count returns no words or error
- Payment failure via x402 protocol results in 402 response before computation

## 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 a 'result' with a hyphenated label string (e.g. 'fox-stone-cloud'), an array of the selected words, and a 'secret_safe' boolean. Also includes an 'evidence' block with a SHA-256 hash of the input, confirmation that no data was retained, and the count of external calls made (always 0), plus a status field ('pass') and operation name.
