## 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 token-diet-mcp-5a838ef1 -d '<json body>'
```

Example prompt: Can you run this through Token Diet to reduce its token count before I send it to GPT-4? Here's the text: 'As a highly experienced and knowledgeable assistant with many years of practice in the field, I will now proceed to explain the following concept in great detail...'

## When to prefer this

Choose this endpoint when you need to reduce token usage before sending text to an LLM, particularly when working with large documents, verbose prompts, or context-window constraints. Ideal for agents that want to cut LLM API costs or stay within token limits without manually rewriting input.

## Known failure modes

- Empty or missing 'data' field returns a validation error
- Extremely large input strings may be rejected or truncated
- Non-text binary data in the 'data' field may cause processing errors
- Payment failure (x402) blocks the request before processing
- Ambiguous or already-minimal input may return unchanged or minimally modified text

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a token-optimized or compressed version of the input text string, reducing overall token count while preserving semantic content or key information.
