## 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 bulgarian-cyrillic-to-latin-transliteration-api-official-bulgarian-680da006 -d '<json body>'
```

Example prompt: Transliterate this Bulgarian text to Latin using the official Bulgarian standard: 'Нова статия за България' — I also need the URL slug version.

## When to prefer this

Choose this endpoint when you specifically need transliteration conforming to the official Bulgarian Transliteration Act 2009 — not ISO 9, not Russian transliteration conventions. It is the right choice for generating legally or officially compliant romanizations of Bulgarian names, places, or documents, and for producing URL slugs from Bulgarian text. It is deterministic (no LLM randomness), affordable at $0.003 USDC per call, requires no account, and handles up to 60000 characters per request.

## Known failure modes

- Empty or missing 'input' field returns a validation error
- Input exceeding 60000 characters is rejected
- Non-Cyrillic or non-Bulgarian input may result in foreign_letters being populated but text still processed
- Payment failure via x402 protocol causes the request to not be fulfilled
- Malformed JSON body returns a parse error
