# Migrate my OpenCorporates integration to Corpo API Read the Corpo API docs index first: https://docs.corpoapi.com/llms.txt Then migrate this repo's OpenCorporates integration to Corpo API. 1. Find every place we call OpenCorporates. 2. Map each field we send or read to its Corpo API equivalent, using the docs for the real names. 3. Update the calls to Corpo API: base URL https://api.corpoapi.com, auth header X-API-Key. 4. Keep behaviour the same: same inputs, same outputs, same errors. 5. List anything with no equivalent, and stop before guessing. Leave unrelated code alone, and run the tests when you are done.
