## 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 ciel-m2m-api-context-compress-8be3c14c -d '<json body>'
```

Example prompt: Can you fetch and compress the content from that documentation page using a GET request so I get a short summary without losing the key information?

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of HTTP-fetched content before passing it to an LLM or downstream agent step. It is especially useful when working within tight context windows, summarizing verbose API responses, or building pipelines where many URLs must be digested cheaply at $0.05 per call via USDC on Base.

## Known failure modes

- Invalid or unsupported HTTP method (only GET, HEAD, DELETE accepted) returns a validation error
- Target URL unreachable or returns non-200 status causes fetch failure
- Input type must be 'http'; other values are rejected
- Empty or non-text content at the target URL may produce poor or empty summaries
- Payment failure via x402/USDC blocks the request before processing

## How this service works

50+ micro-services for AI agents: data parsing, crypto analytics, security scanning, code tools, and more. Pay per call via x402 (USDC on Base) or RapidAPI subscription.

## Output

A JSON object containing a 'summary' string (the compressed version of the fetched content) and a 'compression_ratio' number indicating how much the content was reduced (e.g. 8.5 means 8.5x reduction).
