2121The Availability column in each of the following tables lists the platforms that offer a feature. A platform listed without a label offers the feature as stable, fully supported, and recommended for production use, with no beta header and with standard API [versioning](https://platform.claude.com/docs/en/api/versioning) guarantees. A label after a platform name marks one of the following classifications on that platform. Not all features pass through every stage, and a feature may enter at any stage or skip stages.

112112\* **Structured outputs:** Your prompts and Claude's outputs are not stored. Only JSON schemas are cached, for up to 24 hours since last use. **Web search and web fetch:** ZDR-eligible except when [dynamic filtering](https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool#dynamic-filtering) is enabled. **Fallback credit and server-side fallback:** The features retain no message content, but they handle refusals from the Claude Fable models, which [are not available under ZDR](https://platform.claude.com/docs/en/manage-claude/api-and-data-retention#model-specific-data-retention-requirements). See [ZDR details](https://platform.claude.com/docs/en/manage-claude/api-and-data-retention#feature-eligibility).
