Crustdata API
Crustdata grades A: the product is a documented, versioned REST API with self-serve signup, 100 free trial credits, and published per-credit pricing. Premium contact and live endpoints sit on enterprise plans, and official SDKs are not published, which is all that separates it from a perfect score.

Crustdata scores A on Supergood's API Report Card. Crustdata grades A: the product is a documented, versioned REST API with self-serve signup, 100 free trial credits, and published per-credit pricing. Premium contact and live endpoints sit on enterprise plans, and official SDKs are not published, which is all that separates it from a perfect score.
Crustdata has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Crustdata is a B2B data platform founded in 2024 (Y Combinator Fall 2024) that delivers real-time company and people data through APIs.
Software and data tools. Developers integrate Crustdata endpoints server-side to enrich CRM records, build live prospect lists, screen companies for investment signals, monitor headcount and funding changes through watchers, and feed AI agents with structured firmographic and person data.
Crustdata is a young, fast-growing vendor rather than an entrenched system of record; public reporting describes revenue growth from about $770K to more than $4M in the months after its Y Combinator batch and a $6M seed round in October 2025, with adoption concentrated among AI-native sales, recruiting, and investing products.
Crustdata holds its own licensed and collected dataset rather than customer operating data. Customers store nothing of record in the platform beyond account, billing, watcher configurations, and query history; the asset customers depend on is the freshness of the vendor's data.
Founded 2024, Y Combinator Fall 2024 batch. The stack is modern by construction: REST endpoints with date-stamped versioning (x-api-version 2025-11-01), credit-based metering, watcher notifications, and an MCP server for AI agent access.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Crustdata scores GOOD on MCP availability. Crustdata runs an official hosted MCP server at mcp.crustdata.com with OAuth and API key authentication, documented in its developer docs. Setup guides cover Claude, Cursor, VS Code, and generic streamable HTTP clients.
Yes. Crustdata publishes an official MCP server, so MCP clients like Claude, Cursor, and Codex can connect to it directly. Setup instructions are in the vendor's documentation.
