MentionsAPI

Description

MentionsAPI is a developer API for AI brand visibility and generative engine optimisation (GEO). One call sends a prompt to ChatGPT, Claude, Gemini and Perplexity in parallel and returns which brands were mentioned, their rank, sentiment, surrounding context and every cited URL, in a single consistent response shape.

MentionsAPI appeared on Product Hunt on 3 November 2026. Rather than another dashboard, it supplies the data layer that SEO agencies and GEO tool builders would otherwise have to build themselves, and it also covers Google AI Overviews, Google AI Mode and Bing Copilot, plus live scraping of the ChatGPT, Gemini and Perplexity interfaces.

Who MentionsAPI Is For

MentionsAPI is designed for technical teams building AI-visibility features:

• SEO agencies adding AI visibility to client reports next to search rankings.
• GEO and SEO tool builders who need reliable multi-engine data without scrapers.
• In-house marketing engineers tracking how AI assistants describe their brand.
• Developers building dashboards or alerts with AI tools such as Claude or Cursor.

Core Capabilities

One API, Many Answer Engines

A single endpoint queries the OpenAI, Anthropic, Gemini and Perplexity models in parallel with one bearer token, one rate limit and one response format. Switching providers means editing an array.

Brand Tracking Built In

Pass a list of brands and MentionsAPI returns position, sentiment, context and citations for each mention. Discover suggests query ideas for a brand, and Compare returns a head-to-head difference between two brands.

Live AI Search Surfaces

Beyond the model APIs, you can check Google AI Overviews, AI Mode, Bing Copilot and live ChatGPT, Gemini and Perplexity interface results with their citations and fan-out queries, which is closer to what real users see.

Reliability and Developer Tools

Recently asked queries are cached for cheaper answers, retries are automatic, and partial results come back when a provider is down. There is an OpenAPI 3.1 specification, webhook watches and a hosted MCP server.
