Assessment: A free Lite tier with no request cap, a public OpenAPI document, llms.txt, a batch endpoint of 1,000 lookups and a six-tool hosted MCP server with OAuth. No status page or SLA was found, the only documented error is 429, the token may travel in a query string, and city-level and privacy data need a paid plan.

## Before you call it

1. Call `https://api.ipinfo.io/lite/{ip}` with `Authorization: Bearer` on a free token; `/lookup/{ip}` and `detailed=true` in the MCP tools return ACCESS_DENIED without a paid plan
2. Batch up to 1,000 addresses in one POST to `/batch/lite` or `/batch` with `filter=1`; each address counts as one request against the monthly quota
3. Append a field path such as `/country` or `/asn` to get a single plain-text value instead of the full object
4. On a 429 the monthly plan quota is spent; there is no Retry-After, so stop and report rather than retry
5. Treat the data as licensed for internal use; selling or reselling it needs IPinfo's written consent under the terms
