Overview

Relevance API provides programmatic access to Relevance AI's AI Workforce platform, letting developers integrate autonomous agents into their own applications, workflows, and products. Through the API, teams can trigger agents, manage tasks, and orchestrate multi-step processes that handle work traditionally done by humans. Designed for production use, the API supports building custom AI employees that can carry out research, data processing, sales outreach, and operational tasks. It connects with existing tech stacks and tools, making it suitable for embedding agentic capabilities into SaaS products or internal systems. It is aimed at engineering teams and businesses that want to scale operations with AI agents while retaining control over deployment, data, and behavior.

Key features

  • REST API for agent invocation
  • Custom AI agent creation
  • Task and workflow orchestration
  • Tool and data source integrations
  • Multi-agent collaboration support
  • Usage monitoring and logs

Orchestrate multi-step research tasks

Coordinate multiple agents to perform complex research and data processing pipelines, with task management and logs to monitor progress across long-running workflows.

Add AI employees to internal systems

Engineering teams can connect agents to internal tools and data sources, automating operational tasks traditionally handled by human staff within company workflows.

Solid for our team

We rolled this out across the team last quarter and integrates with existing stacks and tools. Usage monitoring and logs fits neatly into how we already work, and tool and data source integrations removed a step we used to do by hand. but it has held up under daily use.

Use it every day

Honestly didn't expect to like it this much. Custom AI agent creation is exactly what I needed, and supports complex multi-step workflows. but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: usage monitoring and logs and built for production-scale automation. Where it lags: less out-of-the-box than no-code alternatives. On balance the feature set — especially usage monitoring and logs — justifies the 4 stars for our use case.
