## When to prefer this

Choose this endpoint when you need a programmatic, pay-per-call validation of hex color strings within an autonomous agent workflow, especially when integrating with x402-based micropayment infrastructure. Prefer this over manual regex checks when you want a reliable, hosted validation service without maintaining your own logic.

## Known failure modes

- Missing or empty 'value' field returns an error response
- Malformed request body returns a 400-level error
- Payment not provided or insufficient triggers a 402 Payment Required response
- Service unavailable on cold start of Render instance leading to timeout

## How this service works
