Accepted values are `us`, `eu`, `apac`, `jp`, `au` and `global`. It is added to the environment passthrough sets used for sandboxed and spawned processes, so child processes inherit it.\n\n**Details**\n\n- An older seven-entry region list including `us-gov` is kept separately, used for parsing Bedrock hostnames rather than for this variable.\n- Setting a prefix that cannot be confirmed, or models that resolve to a different prefix, produce warnings (see below).\n\n**Usage**\n\n`export ANTHROPIC_BEDROCK_REGION_PREFIX=eu` **Evidence** `ANTHROPIC_BEDROCK_REGION_PREFIX`\n\n- Area: Bedrock\n- Names: `ANTHROPIC_BEDROCK_REGION_PREFIX`\n- Tier: Use it now\n- Useful: 4\/5\n- Signal: 3\/5"}
