> Bot Bazaar UUID/ULID Validator is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Validates a UUID or ULID identifier string and extracts its format, version, variant, and canonical representation.

## 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 bot-bazaar-uuid-ulid-validator-bab591e9
```

Example prompt: Can you check whether '01ARZ3NDEKTSV4RRFFQ69G5FAV' is a valid ULID or UUID, and tell me its format, version, and canonical form?

## When to prefer this

Use this endpoint when you need to programmatically validate and parse UUID or ULID strings — for example before storing identifiers in a database, debugging API responses with suspicious IDs, or classifying identifiers from mixed-format systems. Prefer this over regex-only checks when you need format version, variant, and canonical normalization in one call.

## Known failure modes

- Missing 'id' query parameter returns a validation error
- Non-UUID/ULID strings return invalid result with format details
- Malformed but close strings (e.g. wrong character count) return invalid with reason
- Payment not provided or invalid results in HTTP 402 response
- Network timeout on the Fly.io instance

## How this service works

Validate a UUID or ULID identifier string and extract its format, version, variant, and canonical representation.

## Output

Returns the validation result for the given identifier string, including whether it is a valid UUID or ULID, the detected format (UUID vs ULID), the UUID version (e.g. v1, v4) and variant if applicable, and the canonical (normalized) string representation.
