Agent-First API InfrastructureAPI/InfraDevelopers and companies building agentic appsMedium competition

Moat

First-mover in agent-first API design; proprietary tools for making software agentic.

Key risk

Unclear product clarity from limited description; competition from cloud providers adding agent APIs.

Why now

Agentic era requires new infrastructure primitives; enterprises shifting from chat to agent-first applications.

Competitors

OpenAI platform, Anthropic Claude API, cloud providers (AWS, GCP, Azure)

Zatanna turns human-driven software workflows into reliable APIs for AI agents, by reverse-engineering the underlying network traffic behind portals and exposing a stable API endpoint. It aims to replace browser automation with direct, maintainable API calls that handle auth, retries, and session management automatically.

Zatanna records a workflow, reconstructs the exact underlying API request flow (including login, authentication, sessions, and sequencing), and deploys a single stable endpoint that agents can call. It manages auth, retries, anti-bot detection, and session handling, offering milliseconds latency and avoiding UI dependencies. If portal changes occur, Zatanna’s observability detects issues and repairs the integration automatically, allowing production APIs to stay in sync with backend behavior.

Who it’s for: AI agents and internal tools requiring direct API access to enterprise portals and back-office systems.

Zatanna creates faster, cheaper, and more reliable APIs for AI agents

Zatanna provides APIs for AI agents by reverse engineering workflows on software without public APIs, hosting the underlying request sequences as endpoints to replace browser automation. It targets ERP, PMS, portals, marketplaces, and other operational websites, offering faster, cheaper, and more reliable interactions with session management, retry logic, and traffic handling.
