Agents

Agents API

New API to retrieve specific agent details or a list of available agents on your account. Each agent has a defined type and set of capabilities for resolving business verification signals. View API reference.

Threads API

New API to create and manage agent threads. A thread holds context and history for agent work, typically associated with a business_id. Use threads to maintain state across multiple agent runs for the same Business. View API reference.

Runs API

New API to execute an agent within a thread. A run produces steps and artifacts that provide a full audit trail of the agent’s work, including confidence scores and source references. Runs support an interrupt pattern for human-in-the-loop workflows. View API reference.
