API tokens with viewer/editor/administrator levels. Dataset-level access control. SOC2 Type II. GROQ query language is powerful but agents must sanitize user-supplied queries to prevent data exposure. Read vs write tokens should be separate for agents.

Use Cases

  • Building composable content architectures for enterprise apps
  • Programmatic content migration and transformation

Not For

  • Simple content needs where GROQ learning curve isn't justified

Known Gotchas

  • GROQ is Sanity's custom query language - agents must learn it rather than using standard SQL or GraphQL
  • Real-time listeners use WebSocket connections that require different handling than REST polling
  • Mutations use a transaction format (array of operations) rather than single-operation REST calls
  • Draft documents have a 'drafts.' prefix on their ID - agents querying published content must exclude drafts
  • Image and file asset uploads are separate from document mutations and require two-step process
