## 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-ulid-generator-c8c505d2 -d '<json body>'
```

Example prompt: Generate a ULID for me — I need a unique, lexicographically sortable identifier and I'm happy to pay the $0.001 USDC fee via the Delx Commerce API.

## When to prefer this

Choose this endpoint when you need a ULID specifically (not a UUID or nanoid), require verifiable delivery via blockchain micropayment, want no-signup access, and are operating in an agent context that already handles x402 USDC payments on Base or Solana.

## Known failure modes

- Payment failure if USDC balance is insufficient or x402 payment header is malformed
- Invalid input schema if required fields (input, output) are missing or malformed
- Network timeout if Base or Solana payment settlement is delayed
- Non-200 response if the x402 facilitator rejects the payment
- Empty or malformed JSON response if the upstream ULID generator fails

## 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 freshly generated ULID — a 26-character, lexicographically sortable, time-ordered unique identifier — along with any metadata the API includes in its response envelope.
