Verdicts

ArcGIS Location Platform

Per-unit prices are public for every service, with a monthly free tier of 20,000 geocodes and 20,000 routes, keys limited to chosen privileges and a 99.9 per cent SLA. No rate limits or OpenAPI description were found, results may not be stored unless the dearer stored geocode is bought, and the agreement bars benchmarking without written permission.

Radar

Radar documents 36 REST operations in Markdown with a rate limit on each, and its status feed shows two short API incidents in 90 days. Access is sales-led. The pricing page says there is no free tier, every plan is an annual commitment, and no OpenAPI description or API changelog was found.

Before you call either

ArcGIS Location Platform

  1. Send the token in an X-Esri-Authorization: Bearer or Authorization header. The docs' examples put it in a token parameter, which Esri's own best-practice page calls less secure.
  2. Set forStorage=true on findAddressCandidates or reverseGeocode only when results will be kept. It needs pay-as-you-go and the Geocode (stored) privilege, and costs eight times the unstored rate.
  3. Cap geocoding output with maxLocations (default and maximum 50) and outFields, because billing counts results returned and the default returns every field.
  4. Page place searches with pageSize (maximum 20) and offset. A nearby or extent search costs $8 per 1,000 requests after 500 free a month.
  5. Check the JSON body for an error object with code, message and details. Code 499 means the token is missing and 403 means it lacks the privilege.

Radar

  1. Send the key in the Authorization header with no Bearer prefix, and call https://api.radar.io/v1, not radar.com
  2. Use a publishable key for geocoding, search and routing. Keep the secret key for users, trips, geofences and beacons
  3. Call /v1/search/autocomplete for partial addresses and place names. /v1/geocode/forward is documented as best for complete addresses
  4. Set units=metric on routing calls. The default is imperial, with distances in feet
  5. Treat 429 as one of three things (rate limit, no state change or selective throttling) and 402 as usage exceeded. No Retry-After header is documented
  6. Do not keep geocoding, autocomplete or place results for more than 30 days

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
