MCP + API

Connect your agent.

Search public sources and open research with the same access and budget as your workspace.

01

Create your workspace

100 free credits to try deeper research. Human and agent usage share one balance.

02

Connect an agent

Create a workspace key and add the endpoint to any client supporting Streamable HTTP MCP and bearer headers.

03

Keep your agent in the loop.

Use follow_vendor to follow a public profile, then poll list_workspace_updates. Save its nextCursor and pass it as after on the next check. These are free pull-based updates; your agent decides when to check and how to notify you.

Paid source monitoring and deeper research require a separate, explicit credit budget.
