## When to prefer this

Use this endpoint when you need a paginated, filterable feed of cryptocurrency news from CoinAnk and want to pay per-call with USDC without managing API keys or subscriptions. Prefer this over scraping or registered-API alternatives when low-friction micropayment access is acceptable and you need language or popularity filtering.

## Known failure modes

- Payment not received or insufficient USDC — 402 response returned
- Invalid query parameter types cause malformed request
- Empty data array returned when no news matches the search or type filter
- Upstream CoinAnk API unavailable — gateway may return 502 or timeout
- Invalid lang or type enum values may return empty results or error
