LocationIQ vs MapQuest

LocationIQ

5,000 free requests a day with no card, commercial use allowed with a link back. No changelog, release notes or blog.

MapQuest

One account reaches geocoding, routing, place search and traffic through a REST API or a hosted MCP server with OAuth, at a published $0.0045 a transaction. No API terms, status page, changelog or product OpenAPI spec was found, and REST keys travel in the query string.

LocationIQ

1. Use eu1.locationiq.com for European users or data
2. Add format=json and limit=1 to keep responses small
3. On 429 Rate Limited Second wait a second, on Rate Limited Day stop until the next day
4. Call /balance before a large batch to see what's left of the day's quota
5. Redact the key parameter before logging request URLs

MapQuest

1. Register an account and create an API key before connecting the MCP server. Every tool needs an active key, chosen by nickname on first use
2. Send REST calls to https://www.mapquestapi.com with key in the query string, and redact it from logged URLs
3. Read info.statuscode in geocoding and directions responses. 0 is success, and errors such as 610 (ambiguous location) arrive in the body
4. Set thumbMaps=false and maxResults on geocoding, and pageSize (1 to 50) on place search, to keep responses small
5. Do not store or cache geocodes on a monthly or pay-as-you-go plan
