## When to prefer this

Choose this endpoint when an AI agent needs to verify geographic claims, look up academically sourced location data, or fact-check assertions about a specific place. It is particularly useful when accuracy and sourcing matter more than speed, such as for research tasks, content verification, or grounding geographic assertions in authoritative data.

## Known failure modes

- Missing 'location' field returns validation error
- Unrecognized or ambiguous location name may yield no results
- Payment failure (insufficient USDC on Base) blocks request
- Vague location strings may produce low-confidence or empty results
- Network timeout on third-party academic data sources
