## Overview

Crustdata is a real-time B2B data provider aimed squarely at AI agents and the platforms that run them. Its core claim is that it indexes web pages and parses them into one live graph of people and companies, covering 1B+ people and 60M+ companies. That graph is then exposed through a REST API and an MCP server, so an agent can search, enrich, and monitor records without a human assembling filter menus.

The product set covers Search (people, company, and job queries), Enrichment (person, contact, and company profiles), Signals and Watchers, and pre-built Databases and skills. Data quality is framed around three ideas: freshness (records re-verified continuously, refreshed every 1 to 30 days and live where needed), depth (a whole profile rather than a single row), and resolution (every identity mapped to the right human).

Pricing is credit-based and designed for agents that make thousands of calls. Search costs from 0.03 credits per result, enrichment starts at 1 credit per person, and watchers start at 0.5 credits per new result, with credits lasting 12 months. Every new account starts with $20 in free credits, some calls such as autocomplete are free, and empty search results cost nothing. Enterprise plans with real-time endpoints and custom datasets are quoted by sales.

## Pricing & Plans

Credit-based pricing. New accounts start with $20 in free credits. Search from 0.03 credits per result; person enrichment from 1 credit (1-4 credits with add-ons, up to 9 for everything); contact enrichment 1-5.5 credits; watchers from 0.5 credits per new result. Credits remain valid for 12 months. Autocomplete, company identify, and batch status checks are free. Enterprise plans with live real-time endpoints start at four figures per month.

## Key Features & Capabilities

- **Real-time B2B data API:** Search 1B+ people and 60M+ companies and enrich records via REST API or MCP, with results refreshed every 1 to 30 days and live real-time endpoints available.
- **MCP for AI agents:** An MCP server drops the entire people and company graph into your agent in a single line, so AI agents can act on accurate data instead of stale guesses.
- **Watchers and live signals:** Watchers alert you when a tracked person or company changes or a new match appears, with funding and job-change signals, and you pay only for new or changed results.
- **Credit-based, pay-for-what-you-use pricing:** Searching is cheap and billed per result, so you can explore a wide list first and spend only on the people and companies you actually keep.
- **Deep, resolved person profiles:** Profiles resolve to the right human across sources, with work email, personal email, phone, developer, and research profiles as optional add-ons.

## Primary Use Cases

- **Power outbound prospecting (Sales & GTM Teams):** Enrich and search leads for an AI SDR, build prospect lists, and set up watchers on funding events and job changes to trigger timely outreach.
- **Build candidate lists and pipelines (Recruiting Platform):** Source candidates with resolved work history, skills, and contact details, and monitor job changes to catch talent moves early.
- **Source and monitor deals (Investor / VC):** Track champions, monitor companies for signals, and surface second-time founders and funding events for deal sourcing teams.
- **Feed an AI agent with live B2B data (AI Product Engineer):** Drop the people and company graph into an agent through the MCP so it can search, enrich, and act on live records rather than stale data.

## Strengths

- Very large dataset: 1B+ people and 60M+ companies in one graph
- Fast, accurate search over rich filter sets, with 350+ filters across people, companies, and jobs
- Available both as a REST API and as an MCP server for AI agents
- Generous free entry: $20 in credits, free autocomplete calls, and no charge for empty results
- Watchers and signals cover funding alerts and job-change tracking

## Limitations

- Credit-based pricing can be hard to forecast without monitoring consumption
- Live/real-time endpoints cost more credits than indexed ones
- Enterprise contracts and some endpoints require talking to sales
