# CoCo MIME Type Lookup

> CoCo MIME Type Lookup is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

## 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 coco-mime-type-lookup-6f33e32e
```

Example prompt: What's the MIME type for a .pdf file? Look it up and give me the full content-type string including encoding if any.

## When to prefer this

Use this endpoint when you need a quick, programmatic MIME type resolution for a file extension or filename in an agent workflow, especially when you want encoding and extension metadata alongside the content-type string. It is best suited for single lookups at low cost ($0.001 USDC) with a simple GET interface.

## Known failure modes

- Unknown or unrecognized extension/value returns mime: null
- Missing required 'value' query parameter may return an error or null result
- Ambiguous input (e.g. bare filename without extension) may return null
- Payment failure (402) if x402 micropayment not provided

## Output

A JSON object containing the resolved MIME type string (e.g. 'application/pdf'), the encoding (e.g. null or 'gzip'), and the canonical file extension (e.g. 'pdf'). The mime field may be null if the input is unrecognized.
