> AgentShelf Strip-BOM Text Normalizer is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-29).

## 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 agentshelf-strip-bom-text-normalizer-cb9b581a -d '<json body>'
```

Example prompt: Can you strip the BOM from this text I got from a file: '	efHello world, this came from a UTF-8 file and has an invisible byte order mark at the start'?

## When to prefer this

Use this endpoint when you need a fast, deterministic, no-LLM, no-network operation to strip BOM characters from text. Ideal when you have a string that may have been exported from Windows tools, legacy systems, or UTF-16 sources and need to normalize it before further processing. Prefer this over regex-based BOM removal when you want a reliable, consistent microservice call. Always try the free sandbox endpoint POST /v1/sandbox/norm-strip-bom first to avoid paying $0.006 USDC unnecessarily.

## Known failure modes

- Text exceeds 100,000 character limit — returns validation error
- Empty string input — rejected by minLength:1 constraint
- Missing 'text' field in request body — returns schema validation error
- Payment of exactly $0.006 USDC not provided — returns 402 Payment Required

## How this service works

Call when an agent needs text normalized with strip-bom. No network and no LLM. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/norm-strip-bom first.

## Output

Returns the input text string with any leading BOM characters (such as the UTF-8 BOM \xEF\xBB\xBF or UTF-16 BOM \xFF\xFE / \xFE\xFF) removed. If no BOM is present, the text is returned unchanged.
