What we checked on Exa
Multi-agent
A single Exa Agent run fans out many searches and splits list building into subtasks that run in parallel, so coordination happens inside Exa rather than needing the buyer to orchestrate separate agents.
A single run can fan out many searches across different angles, read and condense the pages behind them, split list building into subtasks that run…
Agent permissions
You constrain a run rather than approve steps: effort modes set a flat price or a per-run spend cap ($5 on auto, $20 on ultra), includeDomains and excludeDomains restrict sources, and an API key can carry its own budget; no step-level human approval is documented.
Metered runs bill actual usage up to their per-run cap. auto defaults to a $5 cap; ultra defaults to a $20 cap

Open source
The clients are open: the MCP server is published as free and open-source on GitHub, the Python and JavaScript SDKs and the benchmark harnesses are public repositories, while the search index and ranking service remain a hosted API at api.exa.ai.
Connect Claude, Cursor, VS Code and other AI tools to Exa's search, code search, and research capabilities via MCP. Free and open-source.

SDK languages
Official SDKs cover Python (exa-py, Python 3.9+) and TypeScript/JavaScript (exa-js); other languages must call the REST API or the OpenAPI spec directly.
The official Exa SDKs. Search the web, get page contents, and get answers with citations.
Tracing and evals
Completed Agent runs return field-level grounding citations and a cost breakdown, stored run events can be listed or replayed as server-sent events, and per-key usage analytics are retrievable through the Team Management API.
Each run can return a natural-language answer, schema-validated JSON, field-level grounding, metadata, and a cost breakdown. You can retrieve…
How it meters
Billing is per request against a prepaid dollar credit balance, with no seats and no subscription: each endpoint has a base price per 1,000 requests, extra results and AI summaries billed on top.
Exa is pay-as-you-go. There is no subscription and no minimum spend: you load credits and are charged per request, at the rates below.

Cost of one job
One thousand Lite search requests cost $4 on the cheapest paid path, each covering up to ten results; extra results add $1 per 1,000 and an Agent research run runs from $0.012 to $1.00 at fixed effort.

MCP server
Exa publishes a hosted MCP server at mcp.exa.ai/mcp plus an open-source implementation, and the hosted endpoint can be tried without an API key at limited usage, so another agent can query Exa directly from Claude, Cursor or VS Code.
Connect Exa search, code search, content retrieval, and research tools to Claude, Cursor, Codex, VS Code, and other MCP-compatible clients. The…

A company can buy it
An organisation buys as a team: teams hold the credit balance, plan and API keys, owners and managers invite members, and Enterprise adds postpaid invoice billing and several teams grouped under one organisation.
Exa organizes usage, billing, and API keys into teams. To set up your company or organization on Exa, create a team and invite your colleagues to it.
Seat model
There is no per-seat charge and no seat floor or ceiling documented: members are invited freely and the team's shared credit balance is what gets consumed, so cost tracks requests rather than headcount.
Everyone on a team shares its credit balance, plan, and API keys.
Pooled budget
One prepaid balance per team funds every member and every API key, rate limits apply to the team as a whole, and credits must be topped up team by team rather than per user.
Credits belong to a team, so top up each team separately.
Admin controls
Admins control spend and throughput rather than behaviour: a key can be given a lower rate limit and a budget that returns 402 when reached, invites carry roles, but no policy engine over what the agent may retrieve is documented.
You can give an individual key a lower limit from the API Keys page, but its traffic still counts toward the team limit.
exa.ai/docs/admin/billing.mdChecked
Single sign-on
Single sign-on is an Enterprise arrangement rather than a self-serve setting: Exa says Enterprise plans offer SSO and SCIM directory sync across several teams grouped in an organisation, and tells buyers to contact support to set it up.
Enterprise customers can also group several teams under an Exa organization with SSO and directory sync. Contact support@exa.ai to set one up.
Opt out of training
Zero Data Retention, under which queries and results are neither stored nor trained on, is enabled per team on Enterprise plans only and does not cover Websets; no opt-out switch exists on the free or pay-as-you-go tiers.
Zero Data Retention (ZDR) is available on Enterprise plans and enabled per team.
Data residency
Region is an Enterprise configuration item rather than a published choice of jurisdictions, and separately Exa blocks API access from sanctioned countries; no list of available storage regions is given.
Configure throughput, regions, and retrieval behavior for your workload.
exa.ai/enterpriseChecked
Getting out
Results come back as data you keep and Agent runs can be listed, retrieved and deleted through the API, but purchased credit is a prepaid balance and free credits expire monthly without carrying over, and no refund path is offered.
The grant does not accumulate: unused free credits from one month do not carry into the next, so this grant never holds more than $10 at a time.
