## 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-capitalize-case-transform-86c43ada -d '<json body>'
```

Example prompt: Can you capitalize every word in this text: 'the quick brown fox jumps over the lazy dog'?

## When to prefer this

Choose this endpoint when you need a deterministic, fast, no-LLM capitalize-case transformation on a text string up to 100,000 characters. Prefer this over an LLM-based rewrite when consistency and low cost matter most. Use the free sandbox POST /v1/sandbox/case-capitalize first if available; fall back to this paid endpoint when sandbox is unavailable or for production use.

## Known failure modes

- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment of exactly $0.004 USDC required; incorrect payment or missing x402 header results in 402 response
- Non-string input types may cause schema validation failure

## How this service works

Call when an agent needs text rewritten with the capitalize case transform. No network and no LLM. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/case-capitalize first.

## Output

The transformed text string with each word's first letter capitalized (capitalize case), returned without modification to any other characters.
