## When to prefer this

Choose this endpoint when you need to discover public transit open data resources, GTFS feeds, or developer APIs from across the live web — particularly when you want current, broad coverage rather than a single curated dataset. Prefer this over static directories when freshness and link diversity matter for transit developer research.

## Known failure modes

- No results found for overly narrow or unusual query
- Stale or broken source links if underlying web pages have moved
- Max results capped at 10; requests above this limit may be rejected
- Query too vague returns generic or off-topic snippets
- Rate limits or payment failure at $0.01 USDC per call may block access
