### Key gotchas

- **`osm_ids` accepts ARRAY or SINGLE STRING, but NOT comma-separated string** — use `["R174737", "W5013364"]` not `"R174737,W5013364"`. Each ID must be prefixed with N/W/R.
- **Overpass API has aggressive rate limiting** — the raw query hit 429 Too Many Requests after sequential nearby/bbox queries. Server retried automatically but latency spiked to ~25s. Space Overpass calls or use timeout_seconds.
- **`query_nearby` latency varies wildly** — 2-9 seconds depending on query complexity and Overpass server load. N
