Abigail API

Abigail gives AI assistants and engineering teams programmatic access to patent prosecution: office action analysis, response drafting, USPTO forms, examiner intelligence, and docket management. The integration path is the Model Context Protocol. Point a compatible assistant at one URL and it gains 45 tools backed by the same system that runs abigail.app.

The older REST developer API at /v1/openclaw/* was retired on 2026-07-18 and its endpoints now return 404. Its pages remain under the Legacy REST API tab for reference only. New integrations use MCP.
