Beautiful, up-to-date docs without the effort. Theneo is an AI-native API documentation and developer portal platform that auto-generates interactive docs from OpenAPI, Swagger, Postman, GraphQL, gRPC, SOAP/WSDL, and AsyncAPI specifications. Its AI Co-pilot can fully generate, enhance, or stay out of the way of human-authored content, while Ask AI Bot, MCP server integration, llms.txt support, smart changelogs, and the Elva API management platform extend the same surface to AI agents. Used by 15,000+ teams including Ticketmaster, Corpay, and SimilarWeb; backed by Y Combinator; SOC 2 Type II, ISO 27001, ISO 9001, and GDPR compliant.

The Theneo API provides programmatic access to manage API documentation projects, workspaces, user access, and API specification imports on the Theneo platform. Supports creating, publishing, and sharing AI-generated API documentation built from OpenAPI, Swagger, Postman, GraphQL, gRPC, SOAP/WSDL, and AsyncAPI specifications. Pairs with the @theneo/cli and @theneo/sdk npm packages and the Theneo GitHub Action for CI-driven docs updates.

Theneo has built AI-powered capabilities since 2022. The platform now spans documentation authoring, search, and agent exposure:
- AI Co-pilot — At import time pick a co-pilot level: full generation, content enhancement, or no AI assistance. Theneo states "harness the power of Theneo's AI Co-pilot to enrich your content."
- TheneoAI Doc Builder — Metered AI documentation generation. Starter is capped at 2,000 actions/month; Business+ is unlimited.
- Ask AI Bot — Embedded assistant that answers developer questions directly rather than returning search results.
- searchAI — GPT-powered search across published docs. Starter caps at 100 responses/month; Business+ is unlimited.
- Smart Changelog — Automated breaking-change detection across OpenAPI imports.
- MCP Server — Exposes a Theneo developer portal as a Model Context Protocol server so AI agents can call documented APIs as tools.
- llms.txt — Auto-generates the discovery index that advertises an API to large language models.
- Elva (May 15, 2026) — Adjacent API management platform for cataloging APIs and exposing them to AI agents via MCP. "The API management platform that makes your APIs agent-ready."
- Cartlis — Open-source AI-powered API governance agent that enforces rules in real time and auto-patches violations.
- 15,000+ teams use Theneo; flagship customers include Ticketmaster, Corpay, SimilarWeb, and Fortune 500 companies.
- Y Combinator-backed; featured in TechCrunch and Forbes; Theneo 3.0 was Product Hunt's #1 Developer Tool.
- Compliance: SOC 2 (annual audits), ISO 27001, ISO 9001, GDPR.
- Security: AES-256 at rest, TLS 1.3 in transit, MFA enforcement, OAuth, role-based access, 7-day point-in-time backups, quarterly internal audits, annual third-party vulnerability assessments.
- EU Data Residency available for enterprise customers (announced May 11, 2026).
