The B2B identity graph, over REST.

GraphIQ.ai's REST API gives developer and data engineering teams programmatic access to our full B2B identity graph. Query 287M organizations, 393M employees, and billions of operational signals across unified v2 endpoints. Every request returns a clean, semantic JSON-LD payload — rate-limited per minute, scaled to your plan.

AST search layer

Power your data workflows with Abstract Syntax Tree (AST) queries.

Traditional B2B data REST APIs force engineers to use flat query parameters. GraphIQ.ai's Abstract Syntax Tree (AST) search layer combines nested logical operators (and, or, not, should) with precise field specifiers, so you can run nested, multi-condition queries in a single request.

POST /api/v2/organizations/search 
{
  "query": {
    "and": [
      { "field": "industry", "eq": "SaaS" },
      "should": [
        { "field": "signal", "eq": "funding" },
        { "not": { "field": "hq", "eq": "US" } }
      ]
    ]
  }
}
Architecture

Core v2 endpoint architecture.

All v2 endpoints accept structured POST bodies with AST query trees. Responses return typed JSON-LD payloads with canonical entity URIs, provenance metadata, and relationship references.

v2 REST API endpoint directory.

POST /api/v2/organizations/search Core engine for company discovery across entity names, corporate trees, revenue, technology stacks, geography.
POST /api/v2/people/search Track 393M professionals by title, department, seniority, skills, verified contact details.
POST /api/v2/news/search Stream real-time operational trigger events filtered by org ID, keyword, date, sentiment.
Capability Signal feed Pull signals for watched entities by signal type, date range, or recency.
Capability Lookalike discovery Submit seed set of entity IDs, return ranked matches with rationale.
Capability Buying group resolution Query decision-making unit within an account.

FAQ

Frequently asked questions

What is the difference between the REST API and the MCP server?

REST for traditional integrations — ETL pipelines, batch enrichment. MCP for AI agents that need to query the graph as part of an active reasoning loop.
