## When to prefer this

Use this endpoint when you need Polygon market holiday data without wanting to manage API keys or subscriptions — ideal for pay-per-call usage via a crypto wallet (USDC on x402 protocol). Prefer this over traditional market data APIs when building lightweight agents that need occasional holiday lookups without ongoing authentication overhead.

## Known failure modes

- Empty data array returned if no holidays match the query
- Payment failure if wallet has insufficient USDC balance
- Invalid or malformed properties parameter returns error
- Network timeout if the claw402 gateway is unavailable
- Non-zero code in response body indicating an upstream data error
