would like to know this too ;D

there is env.ENABLE_PROMPT_CACHING_1H_BEDROCK - but that is - as the name says "when using Bedrock"

for the raw API the docs are also clear -> "ttl": "1h" https://platform.claude.com/docs/en/build-with-claude/prompt...

but how to make claude-code send that when paying by API-key? or when using a custom ANTHROPIC_BASE_URL? (requests will contain cache_control, but no ttl!)
