FAQ
Frequently asked questions
What is TAM Graph?
TAM Graph is a B2B lead database built for AI agents. It holds 60M+ company records and 408M+ people, with work emails and mobile numbers. You can search it from the website, download results as CSV, query it over a REST API, or connect an agent to it over MCP.
Is there a B2B lead database with unlimited CSV exports?
TAM Graph exports are unlimited on Pro. Download any result as a CSV and import it into your CRM or outreach tool. There are no per-row charges and no export caps, only the fair-use ceiling of 500,000 records a day.
How do AI agents access TAM Graph?
Two ways. The MCP server exposes four tools — the dataset catalog, dataset search, a merged company record, and a domain's email pattern — to Claude, Cursor or your own agent. Or call the REST API at api.tamgraph.com directly with an X-API-Key header. The MCP server is a single file, served at tamgraph.com/mcp_server.py.
What does TAM Graph cost?
Pro is $199 a month, billed monthly. That covers unlimited company and contact search, unlimited lookalike search, every niche index, the email finder and unlimited CSV exports, through the website, the API and MCP. No seats, no credits, no per-record pricing.
Is there a free trial?
Yes: 50 requests, lifetime, at the full Pro speed of 5 requests a second. A card is required to activate the trial and is never charged during it. Once the 50 are used, requests return 402 until you upgrade. The trial also allows 3 agent searches a day.
Which datasets are included?
Directly queryable: companies (36M global companies), local (2.3M US local businesses with emails), places (7.2M US local businesses from Google Maps), ecommerce (2.9M online stores with revenue estimates and installed apps), startups (1.7M companies with funding data) and saas (170k SaaS companies). GET /v1/datasets returns the catalog with sizes and allowed filters.
How accurate are the emails?
Every contact row carries an email_status column. verified_source means the address comes from verified data. pattern_guess and reported_format_guess mean it was built from the domain's naming pattern. none means there is no address for that person. A guess is always labelled as a guess.
Is there an API?
Yes. The base URL is https://api.tamgraph.com and auth is an X-API-Key header; the key is issued instantly at signup. Endpoints: POST /v1/find, GET /v1/datasets, POST /v1/search/{dataset}, GET /v1/company/{domain} and GET /v1/email-pattern/{domain}. The OpenAPI spec is at api.tamgraph.com/openapi.json.
What are the rate limits?
5 requests a second on both the trial and Pro. Query timeout is 20 seconds. Fair use on Pro is 500,000 records a day, with no monthly cap. Agent searches are capped at 3 a day on the trial and 25 a day on Pro.
Can I search for people, not just companies?
Yes. Describe the people you want — for example CMOs at US SaaS companies between $1M and $10M ARR — and the agent builds the company list first, then finds the people at those companies. Each row has full_name, title, company and an email with its email_status.
How does lookalike search work?
Give a domain, or a list of customer domains, and TAM Graph runs a vector-similarity search over company embeddings and returns the nearest matches, ranked. Pro allows up to 10,000 ranked matches per seed, and lookalike searches are unlimited.
Can I cancel any time?
Yes. Cancel from the dashboard; access runs to the end of the month you have paid for. Billing is handled by Stripe.
