API Reference Rewritten: Real Error Responses, HMAC Endpoints and Host-by-Host Breakdown
The API Reference page now tells the truth about errors and hosts. It explains which endpoints live on
opensolr.com (management) and which on api.opensolr.com (AI & Data Ingestion), lists the four HMAC-signed endpoints, and documents the real error responses (HTTP 200 with "status": false for application errors, 403 for authentication, 429 with Retry-After). Two commands that referenced non-existent endpoints were removed from the Solr Migration guide.
