API Reference

API overview

Introduction to the CSR Foundry REST API — authentication, endpoints, and conventions.

CSR Foundry exposes a REST API for programmatic access to projects, estimates, reference data, and user management. The API is available to customers on the Professional and Enterprise tiers.

Conventions

• Base URL: https://api.csrfoundry.net (production)
• Format: JSON request and response bodies
• Authentication: Bearer tokens via API keys generated in account settings
• Versioning: URL-path versioned (e.g. /v1/projects)

What the API can do

The API covers the operations you'd expect:

• Create, read, update, and delete projects and estimates
• Read and write line items, folders, and reference libraries
• Manage users, roles, and permissions
• Trigger exports (Excel, PDF, structured JSON)

Full reference coming soon

Per-endpoint documentation with request / response schemas, rate limits, error codes, and code samples is in progress. While the detailed reference is being written, customers with API access can email sales@csrfoundry.net for specific endpoint examples or integration guidance.

Rate limits and quotas

The API enforces rate limits per account to protect service reliability. Specific limits are published alongside each endpoint when the full reference ships.
