# BlitzAPI > B2B data API for GTM builders: company search, people search, profile enrichment, verified work emails, US phone numbers, job postings and identity resolution behind one API key. Every endpoint and every data type is open on every plan; plans differ by speed, fair use policy and support. Start at $99/month: 10 requests per second per endpoint, fair use policy of 200,000 records a month, basic support. Scale at $499/month: 25 requests per second per endpoint, fair use policy of 5,000,000 records a month, priority support. Build Your Infra from $999/month: fully custom (rate limits, fair use policy, SLA, DPA, reseller agreement, dedicated servers, zero data retention, Slack support, monthly call, custom features), only on a discovery call: https://cal.com/antoine-blitz-acepmu/discovery-call-build-your-infra-blitz-api. One record is one item the API returns to you: one company, one person, one email address, one phone number or one job posting. A call that finds nothing counts nothing. The fair use policy is a monthly volume of records: at the limit, calls pause until the next billing cycle or a plan upgrade. Every account starts with 1,000 free records, no card, self serve. Verified emails are proven against live mail servers and re-tested at least every 30 days; an address that cannot be proven comes back Not Found instead of a guess.

List the titles you would accept, from your ideal buyer down to the founder, and search them in that order inside each company. The search keeps the first match and stops there, so a 15-person startup and a 5,000-person company each give you their real decision maker. - [Agentic commerce: how AI agents find, buy and use B2B data](https://www.blitz-api.ai/guides/ai-agents): Agentic commerce is commerce where the buyer is an AI agent: it finds a product, reads the price, pays and uses what it bought, without a person filling in forms for it. With BlitzAPI and ZeroClick, an AI agent finds B2B data on companies, people, emails and jobs, buys it per record from a prepaid balance, and calls the API in the same run. - [Claude MCP: how to connect Claude to live B2B data](https://www.blitz-api.ai/guides/ai-agents/mcp-b2b-data): To set up Claude MCP for B2B data, add a remote MCP server as a custom connector: in Claude, open Customize, then Connectors, add https://api.blitz-api.ai/mcp and sign in with your BlitzAPI account. Claude can then search and enrich people and companies, find verified work emails and search job postings while you chat, and each tool call counts records like an API call. ## Solutions by team - [GTM Engineers](https://www.blitz-api.ai/teams/gtm-engineers) - [Outbound Specialists](https://www.blitz-api.ai/teams/outbound-specialists) - [SalesOps & RevOps](https://www.blitz-api.ai/teams/revops) - [Software Developers](https://www.blitz-api.ai/teams/developers) - [Agencies](https://www.blitz-api.ai/teams/agencies) ## Brand The name is written BlitzAPI, one word.
