## 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 lilambd-colors-search-3e1215bc
```

Example prompt: Search the lilambd colors database for colors associated with the word 'melancholy' and return up to 20 results.

## When to prefer this

Use this endpoint when you need to look up colors by a descriptive word or concept — especially for creative, linguistic, or emotional associations between language and color. It is distinct from color conversion tools (hex/RGB) or palette generators; it operates as a searchable color lexicon.

## Known failure modes

- Empty result set (data:[], count:0) when no colors match the query word
- Missing or malformed 'q' parameter may return all or no results
- Offset beyond available records returns empty data array
- Payment failure (402) if x402 USDC payment is not provided or rejected
- Rate limiting or server errors returning non-200 status

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing a 'data' array of matching color records, a 'count' integer indicating how many results were returned, and an 'attribution' string with the source license line for the underlying color data.
