## Overview

Metaphor Systems is the earlier name of the company now known as Exa, and the old domain redirects straight to exa.ai. The underlying product is unchanged: a search engine and API that treats the public web as a retrieval layer for AI. Rather than optimising for a human reading ten blue links, Exa optimises for an agent that needs accurate, recent context it can paste into a prompt.

The API spans several products. Search returns ranked results with optional full contents and AI-generated highlights; Contents fetches page text, summaries and metadata; Agent runs longer research tasks asynchronously and returns structured JSON with citations; Monitors watch topics, people or companies on a schedule and fire webhooks. The company also publishes an independent index measured in hundreds of billions of documents and two trillion tracked URLs, and it is a common building block behind coding assistants, chatbots and GTM enrichment workflows.

Exa is developer-first: you sign up, get an API key and call endpoints, with playgrounds and documentation to test queries. Pricing is usage based, and enterprise customers can negotiate custom indexes, data-provider access through Exa Connect, SLAs and zero data retention.

## Pricing & Plans

Free Starter tier with about $10 of credits per month plus an onboarding bonus, no payment method required. Developer pay-as-you-go pricing starts around $4 per 1,000 searches, with Contents at roughly $1 per 1,000 pages and Agent runs priced per effort level. Custom Enterprise plans and startup/education credit grants are available.

## Key Features & Capabilities

- **Search API for agents:** Low-latency search endpoints (Lite, Auto, Deep) return ranked pages, highlights and structured fields from an independent index covering a large share of the public web.
- **Contents and highlights:** Retrieve full page text or token-efficient highlights with configurable crawl policies, so models get only the most relevant excerpts rather than whole documents.
- **Deep research and Agent endpoint:** Run asynchronous agent runs that navigate, reason and return structured outputs with grounded citations across 70M+ companies and other verticals.
- **Monitors for fresh events:** Schedule recurring queries over news, people, companies and financials, and receive updates through webhooks when something changes.
- **Ready-made integrations:** First-party MCP server, Claude Connector and ChatGPT plugin plus SDKs, so Exa slots into existing agent frameworks with minimal glue code.

## Primary Use Cases

- **Ground RAG pipelines (AI engineers):** Give chatbots and copilots an up-to-date search tool so responses cite current pages instead of static training data.
- **Power coding agents (Developer tooling teams):** Query repos, docs and changelogs at low latency to keep generated code aligned with current package and API references.
- **Automate research and GTM enrichment (Sales and research teams):** Use Monitors and Agent runs to track companies, people and markets on a schedule and receive webhook alerts.

## Strengths

- Purpose-built for LLM retrieval rather than human click-through
- Wide endpoint coverage: search, contents, deep research and monitoring in one API
- Free monthly credits make prototyping cheap
- Strong ecosystem of MCP, Claude, ChatGPT and SDK integrations
- Published compliance posture including SOC 2 Type II and optional zero data retention

## Limitations

- Effectively a developer/API product, so non-technical users need a client or integration to get value
- Pricing scales by endpoint and result count, so costs can climb with heavy agent traffic
- Historical Metaphor branding is deprecated, and old links/references may be confusing
