Claude Code gateway compatibility guide changedllm-gateway-protocol

Nearest release: v2.1.294, published an hour after upstream edited the page. Shown because the two are within 24 hours of each other. Nothing here says the release caused the edit.

Upstream edited this page at 8 Oct 2026 02:03 UTC, give or take a minute or two: the time comes from Anthropic’s own sitemap rather than from a commit. This site recorded the change at 8 Oct 2026 02:07 UTC.

173173| Header | What to return and why |
174174| :- | :- |
175| `content-type` | Return `text/event-stream` on streamed Anthropic Messages-format responses, and `application/vnd.amazon.eventstream`, unmodified, on Amazon Bedrock-format responses, where [a different type fails the request](/docs/en/amazon-bedrock#streaming-errors-behind-a-gateway-or-proxy). [Streaming](#streaming) lists which connections run stall detection on these streams |
175| `content-type` | Return `text/event-stream` on streamed Anthropic Messages-format responses, and `application/vnd.amazon.eventstream`, unmodified, on Amazon Bedrock-format responses, where [a different type fails the request](/docs/en/amazon-bedrock#streaming-errors-behind-a-gateway-or-proxy) |
176176| `retry-after` | Return integer seconds rather than an HTTP date. Claude Code waits at least that long before the next [automatic retry](/docs/en/errors#automatic-retries), and outside [`CLAUDE_CODE_RETRY_WATCHDOG`](/docs/en/env-vars) sessions a value above 60 stops the retries and shows the error at once |
177177| `x-should-retry` | Pass the upstream's value through unchanged. Claude Code reads this header as one input when deciding whether to retry a failed request: `true` marks the response retryable and `false` marks it not retryable. For retry counts, backoff, and which failures Claude Code retries, see [automatic retries](/docs/en/errors#automatic-retries) |
178178| `anthropic-ratelimit-unified-*` | Forward the upstream's values unchanged on every response. Claude Code reads them on successful responses to show usage against plan limits to developers signed in with claude.ai, and on a `429` to tell a plan limit or spend cap from a temporary throttle; see [usage limits](/docs/en/errors#usage-limits) |
