ServiceGraph
Stop scraping. Your AI agent gets a structured catalog of 100k+ US professional-services firms — pluggable as a one-line skill install.
What is ServiceGraph?
ServiceGraph is a structured, AI-ready directory and catalog specifically designed for AI agents and automation workflows. Its core purpose is to provide a plug-and-play, structured dataset of over 100,000 US-based professional services firms. It eliminates the need for AI agents to perform unreliable web scraping by offering a clean, queryable API that can be integrated into various AI coding assistants and platforms via the Model Context Protocol (MCP). The catalog covers a wide range of industries including law, marketing, consulting, accounting, IT, architecture, engineering, HR, PR, and design.

- BYO List Support
- Allows users to enrich their own lists of company domains by hashing them and directly fetching firm data via the API without a search query.
How to Use ServiceGraph
ServiceGraph is designed for seamless integration into AI agent workflows. The primary method is through the Model Context Protocol (MCP).
- Install the Skill: Within your supported AI agent (e.g., Cursor, Claude Code), run the installation command:
npx skills add nostrband/servicegraph. - Explore the Catalog (Free): Use the
/v1/exploreendpoint to anonymously discover available industries, services, and filter options. This does not require authentication. - Execute Searches: Once the skill is active, you can prompt your agent with natural language requests. For example: "Find me three boutique IP law firms in California that handle patent prosecution for hardware startups." The agent will construct the appropriate API call to
/v1/search. - Fetch Detailed Data: Retrieve comprehensive profiles for specific firms using the
/v1/get/:idendpoint by providing the firm's unique ID. - Enrich Custom Lists: Hash your own list of company domain apexes and query them directly against the API for CRM enrichment or sales prospecting without consuming search quota for non-existent firms.
Pricing and Free Tier
ServiceGraph offers a generous free tier to get started:
- 200 Firm-Views/Month on `/v1/search`
- You can view detailed data for up to 200 unique firms per calendar month through search queries.
- 50 Firm-Views/Month on `/v1/get`
- You can fetch full profiles for up to 50 unique firms via direct ID lookup.
- Quota Efficiency
- Quota is counted per unique firm, not per API call. Re-querying or overlapping result sets does not double-charge your quota.
- Free Catalog Discovery
- All catalog exploration endpoints (
/v1/explore,/v1/check,/v1/tags) are completely free and subject only to IP-based rate limits. - Authentication
- A simple email-based, passwordless sign-in (using a 6-digit one-time code) is required only when accessing firm card data or contact bundles.
Helpful Tips for Maximizing ServiceGraph
- Leverage Structured Filters
- Move beyond keywords. Combine filters for
industry,state,service_provided,size_signal, andmin_ratingto get highly precise shortlists instantly. - Use for Prospecting and Enrichment
- It's perfect for building targeted sales lists or enriching existing CRM data with structured firm attributes.
- Understand the BYO Workflow
- If you have a list of domains, hash them locally to create firm IDs. You can then check their presence and fetch data directly, which is efficient and doesn't use search quota for missing firms.
- Explore Before Searching
- Use the free
/v1/exploreendpoint to understand the scope of the catalog and validate your filter combinations before executing a search that consumes quota.
Frequently Asked Questions (FAQ)
Do I need an API key to try it?
No. Catalog discovery is fully anonymous. Sign-in is only required when you request detailed firm data or contact information.
How fresh and reliable is the data?
The catalog is continuously refreshed from public web sources (firm websites, directories, registries). Firm classification is performed by LLMs analyzing the firm's own content. Stale data is purged, and new firms are added through ongoing crawling.
Can I use it with any AI agent?
It works seamlessly with any AI agent that supports the Skills/MCP convention, which includes many popular coding assistants. For others, you can call the REST API directly using the provided documentation.
Is the data only for US firms?
Yes, for v1. The catalog is explicitly scoped to US professional-services firms. International coverage is a planned future expansion.
What if a firm I'm looking for isn't in the catalog?
The /v1/get endpoint will return a 404 error, which does not charge against your quota. Your agent can handle this gracefully. Coverage is extensive and growing; you can request specific firms to be prioritized for indexing.
How is this better than a Google search?
ServiceGraph provides structured, filterable data—not unstructured search snippets. You can query by precise industry categories, service tags with confidence levels, firm size, geographic service area, and verified ratings, returning a clean, actionable list instead of pages of mixed results to manually sift through.
