AgentData vs ZoomInfo: company intelligence without the annual contract
ZoomInfo for enterprise depth on an annual contract; AgentData for the company layer an agent needs, free, today.
ZoomInfo is the enterprise reference: 100M+ companies, hundreds of millions of contacts, intent data, org charts, Copilot, and now an MCP server at mcp.zoominfo.com. Paid plans are quote-only annual contracts with seat minimums (Vendr's February 2026 median: about $33,500 a year), with a free ZoomInfo Lite tier of 10 credits a month and a new self-serve GTM.AI developer tier that starts with 1,000 free data credits then $0.38 a credit. AgentData is free without a contract: company profile, 3,968-technology tech stack, verified emails, people and switch signals, 1,000 lookups a day, REST API and MCP included. Verified 17 September 2026.
ZoomInfo is what you buy when you have a revenue team of forty and a procurement department. It's also, to its credit, the incumbent that has moved fastest on agents: the MCP server is real, the free lookup tools in it are useful, and the self-serve GTM.AI tier is a genuine change of posture. What hasn't changed is the shape of the main product: an annual contract, seat minimums, and credits that decide what you can export. We built AgentData for the people ZoomInfo was never for: the founder, the two-person RevOps team, the developer with an agent and no budget line. Same category of data, no contract, and the tech stack ZoomInfo files under 'more robust credits'.
The verdict
Choose AgentData if you…- don't have, or don't want, an annual contract with seat minimums
- need company intelligence (tech stack, switch signals, web signals) more than contact volume
- are building an agent and want an API and MCP with no credit ledger to manage
- work outside the US and want profiles built from the company's own site
- want to start in two minutes, free
- run an enterprise revenue team that needs intent data, org charts, Scoops and Copilot
- need contact volume and direct dials at scale with compliance tooling
- want website visitor identification and CRM-native workflows (GTM Studio)
- have the budget and want account management
One company, two responses
ZoomInfo's current API (docs.gtm.ai) is a two-step search-then-enrich: search is free and returns basic fields; enrich costs one data credit per new company and the docs don't publish an example payload (the reference page is interactive only). Below is ZoomInfo's documented request shape and AgentData's documented response. Read 17 September 2026.
// step 1: search (0 credits; returns name, limited location, website, "few other basic data points")
POST https://api.zoominfo.com/gtm/data/v1/companies/search
{ "data": { "companyName": "Acme Corp", "companyWebsite": "acme.com" } }
// step 2: enrich (1 data credit per new record; up to 25 companies; outputFields required)

"outputFields": ["id", "name", "website", "revenue", "employeeCount", "industry"] } }
// response: JSON:API envelope { "data": [{ "id", "type", "attributes": { ... } }] }
// "no public example payload" — docs.gtm.ai reference page is Try-It onlyOAuth 2.0 (PKCE or client credentials); rate limits by tier (Builder 5 req/s, Standard 25, Scaling 35); records stay “under management” for a year and re-enrich free. Technographics sit behind “more robust credits”.

128M domains indexed, daily refresh, globalPricing: AgentData vs ZoomInfo
ZoomInfo's core plans are quote-only annual contracts. Its two entry points that do have public terms are ZoomInfo Lite and the GTM.AI developer tier, so the honest comparison is those against $0.
ZoomInfo Professional, Copilot Advanced and Copilot Enterprise are sold by quote as annual upfront contracts with minimum seats; ZoomInfo's own blog says monthly billing is not standard. Vendr's marketplace data (February 2026, 1,572 contracts) shows a median of $33,500 a year, range $7,207 to $155,910. ZoomInfo Lite is free with a business email at 10 credits a month (25 if you contribute contacts via Community Edition); credits don't roll over. The GTM.AI developer tier gives 1,000 data credits and 1,000 AI credits once at signup with no card, then top-ups from $20 at $0.38 per data credit and $0.05 per AI credit, no contract, no seats. On that tier, enriching 500 new companies a month after the free credits run out is about $190. AgentData: $0 at 1,000 lookups a day.
How ZoomInfo's packaging has changed
- June 2021 (Arquivo.pt capture): Professional / Advanced / Elite; credits defined as “consumption (export) of a professional or company profile”; pricing “based on features and functionality, number of licenses, credit usage”.
- April 2022 (capture): repackaged as SalesOS / MarketingOS / RecruitingOS / OperationsOS.
- 2023–2024: pricing-page captures return 403 (bot-blocked); no readable data.
- 17 September 2026 (live): ZoomInfo Professional / Copilot Advanced / Copilot Enterprise, still quote-only. New: MCP server at mcp.zoominfo.com/mcp; GTM.AI self-serve tier with 1,000 free data credits and $0.38-per-credit top-ups; ZoomInfo Lite free tier at 10 credits/mo.
- ZoomInfo's free-credit messaging is inconsistent: zoominfo.com/solutions/zoominfo-mcp says 100 free credits for ChatGPT and Claude; gtm.ai says 1,000 + 1,000 at signup; gtm.ai/docs/mcp says a ZoomInfo subscription is required. We quote all three.
- AgentData: $19 / $49 / $99 specced April 2026, never launched; free since May 2026.
AgentData vs ZoomInfo, feature by feature
Enterprise depth: ZoomInfo's strongest card
Intent, org charts, Scoops, Copilot and website visitor identification are a platform, not a dataset.
- AgentData: Company profile, tech stack, verified emails, people, web and switch signals. No intent, no org charts.
- ZoomInfo: Intent data (210M IP-to-org pairings), org charts, Scoops, Copilot AI agent, GTM Studio workflows, website visitor tracking, Data-as-a-Service.

Technographics: included vs metered
Both have tech data; only one charges extra for it.
- AgentData: 3,968 technologies with confidence in every lookup; switch events per company.
- ZoomInfo: Technographics exist but sit behind “more robust credits” alongside budgets and org charts; no technology-change events.

Who moves from ZoomInfo to AgentData
The quote came back five figures for three seats. AgentData covers the company layer for $0; keep ZoomInfo only if you need intent and org charts.
ZoomInfo's MCP is capable and its lookups are free, but enrichment draws on a contract's credits. Ours has no ledger to reconcile; point the agent at it and let it work.
You want the same shape of company data without the renewal conversation. Export your accounts, re-enrich by domain, and see what you lose (intent, dials) against what you gain (tech stack, signals, $0).
Switching from ZoomInfo
- Export accounts and contacts from ZoomInfo (or from the CRM they were synced into). Keep the company website/domain; that's the join key.
- Re-enrich by domain in AgentData via /api/v1/lookup or the MCP; compare verified emails and confidence against ZoomInfo's on 100 accounts you know, and note the tech stack and signals you didn't have.
- Check your contract's notice terms before cancelling; ZoomInfo is annual upfront. Consider dropping to Lite or GTM.AI credits if you still need occasional intent or Scoops.
Field map: ZoomInfo → AgentData
Where ZoomInfo fits better
- You're an enterprise revenue team. Intent data, org charts, Scoops, Copilot and GTM Studio are a platform we don't try to be.
- You need contact volume and direct dials at scale, with compliance tooling and account management.
- You want website visitor identification tied to the same contact database.
- You already have the contract and the integrations, and switching costs more than the renewal.
We would rather you pick the right tool than ours for the wrong reasons. Plenty of teams keep ZoomInfo for the platform and use AgentData for tech-stack prospecting the contract doesn't cover.
