Developer Platform

    Build on the agentic intake-to-pay platform

    Blackbee's APIs give developers programmatic access to 14 autonomous AI agents across intake, procurement, contracts, approvals, and payment. Extend Blackbee into your stack, orchestrate custom workflows, or embed agentic intelligence into your own applications.

    What you can build on Blackbee

    Four common patterns we see from partners building on our platform

    Custom intake sources

    Pipe requests from Slack, email, internal tools, or Teams directly into Blackbee's agentic workflow. Our Intake Agent handles parsing, enrichment, and routing automatically.

    Orchestration and automation

    Trigger Blackbee agents from n8n, Zapier, Power Automate, or custom pipelines. Build approval flows, vendor onboarding, and payment release logic that span your entire finance stack.

    Analytics and data warehouses

    Stream agent decisions, spend events, and approval audit trails into Snowflake, BigQuery, Databricks, or your internal BI tools. Every decision is explainable and queryable.

    Embedded finance workflows

    Embed Blackbee's agents into your own product. White-label the intake-to-pay layer for your customers or surface agent decisions inside your vertical SaaS platform.
