# Citation Locator Conversion

> Citation Locator Conversion is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.024/call, status unknown (last checked 2026-10-24).

Converts text span offsets between UTF-8 byte positions, UTF-16 code-unit positions, and Unicode code-point positions, rejecting invalid mid-codepoint offsets.

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 citation-locator-conversion-f680c611 -d '<json body>'
```

Example prompt: I have a text snippet and a set of half-open spans in UTF-8 byte positions — can you convert those locators into all three formats: UTF-8 bytes, UTF-16 code units, and Unicode code points? The data class is synthetic.

## When to prefer this

Use this endpoint when you need to accurately convert text span offsets between UTF-8 byte positions, UTF-16 code-unit positions, and Unicode code-point positions, especially for multilingual or emoji-containing text where encoding boundaries differ. It is ideal for citation tracking, NLP annotation pipelines, and cross-platform text editor synchronization where encoding mismatches cause bugs. It does not do PDF parsing, page inference, or any external lookups — it is a pure, deterministic conversion utility.

## Known failure modes

- Offset falls inside a multi-byte code point — endpoint rejects the locator with an error
- Input text is not valid UTF-8 — parsing fails
- Locator array exceeds 64 items — request rejected
- Sources array exceeds 16 items — request rejected
- Invalid dataClass value — request rejected with schema validation error
- Malformed body or missing required fields — 400-level error returned

## How this service works

Convert half-open UTF-8 byte, UTF-16 code-unit, or Unicode code-point spans into all three units for supplied text. Reject offsets inside a code point. No PDF parsing, page inference, or external source lookup.

## Output

Returns a result object containing converted offset spans in all three encoding formats (UTF-8 bytes, UTF-16 code units, Unicode code points) for each input locator, a boundaries array, an inputDigest, a receiptDigest, an offerId, a version, and an amountBaseUnits field. Invalid offsets that fall inside a code point are rejected with an error.
