## 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-flat-case-text-transform-f8adcc40 -d '<json body>'
```

Example prompt: Can you rewrite the text 'Hello World Example String' using the flat case transform so it comes out as all lowercase with no spaces or separators?

## When to prefer this

Choose this endpoint when you need a deterministic, offline flat case conversion at a fixed cost of $0.006 USDC. It performs no LLM inference and no network calls, making it fast and consistent. If an unpaid sandbox version at POST /v1/sandbox/case-flat is available, prefer that first to avoid costs during development.

## Known failure modes

- Empty string input returns a validation error (minLength:1 not met)
- Text exceeding 100,000 characters returns an error (maxLength exceeded)
- Malformed JSON body returns a 400 Bad Request
- Insufficient USDC balance or missing x402 payment header returns a 402 Payment Required

## How this service works

Call when an agent needs text rewritten with the flat case transform. No network and no LLM. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/case-flat first.

## Output

Returns the input text transformed to flat case: all characters lowercased and spaces/separators removed, producing a single continuous lowercase string. No LLM or external network call is made; transformation is deterministic and purely local.
