DomainCrust integrations

DomainCrust Developer Resources

This is the named starting point for developers and agents integrating with DomainCrust. Use the public REST API for structured domain sales research, download the OpenAPI contract for typed requests and responses, read the versioning policy before building a long-lived integration, or install the official CLI for scripted workflows. These resources describe the current DomainCrust product surface and link to the canonical files.

DomainCrust integration basics

The production API base URL is https://domaincrust.com/api/v1. Read endpoints cover historical sales search, individual domain history, market statistics, TLD statistics, platform statistics, and top sales. Write operations are protected and require an API key with the required permission in the X-API-Key header.

Responses are JSON objects with a success flag, structured data or error content, and request metadata. API responses expose RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset; a 429 response includes Retry-After. Agents should use those fields to self-throttle instead of guessing.

DomainCrust does not currently publish a public webhook or MCP server endpoint. The supported machine-readable integration surfaces are the REST API, OpenAPI JSON/YAML files, `llms.txt`, and the official CLI. For questions about access, contact api@domaincrust.com.
