## 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 discord-username-availability-checker-49c08938 -d '<json body>'
```

Example prompt: Can you check if these Discord usernames are available: coolcat, nightowl99, blazerking, and stormchaser? I want to know which ones I can still register.

## When to prefer this

Choose this endpoint when you need to programmatically verify Discord username availability in bulk (up to 500 at once) with pay-per-call pricing and no charge for failed or empty runs. It is purpose-built for Discord specifically, unlike general social media availability checkers, and returns structured per-username results suitable for downstream automation.

## Known failure modes

- Username input list is empty or missing — returns empty result, no charge
- More than 500 unique usernames submitted — capped at maxItems limit
- Individual username check fails — error and errorCode populated per item, others still returned
- Network or scraping failure on Discord side — error returned per affected entry
- Invalid username format — may return error per entry

## How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.

## Output

Returns a JSON object with a count of checked usernames and an items array where each entry contains the username, its availability (true/false), the timestamp it was checked, any error message and error code if the check failed, and quota metadata. Failed or empty runs are not billed.
