## 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 agenttools-mime-type-lookup-41073a67
```

Example prompt: What's the correct MIME type for a .webp image file? Search the MIME types database and return up to 5 results.

## When to prefer this

Choose this endpoint when an agent needs to programmatically resolve a Content-Type header value from a file extension or partial type name, or enumerate all MIME types in a given category. It covers all major media type categories (text, application, image, audio, video, font, multipart, model) and is ideal for HTTP API construction, file upload validation, and content negotiation tasks. Prefer it over a web search when you need structured, machine-readable MIME type data with consistent formatting.

## Known failure modes

- No results returned when query string doesn't match any known MIME type substring or extension
- Invalid category enum value returns an error or empty result
- Missing or malformed query parameters may result in an unfiltered full list or API error
- Network timeout if the upstream MIME database is unavailable

## How this service works

Look up MIME content types by type substring or file extension, or list a category — covering text, application, image, audio, video, font and multipart types used in web APIs. Use this when an agent needs to content-Type lookup by type or file extension.

## Output

Returns a list of matching MIME type records, each including the content-type string, associated file extensions, and category. Results are filterable by type substring, file extension query, or category enum (text, application, image, audio, video, font, multipart, model), and capped by an optional limit parameter.
