You're running FxEmbed locally without a host header set to a valid realm domain. This means instead of falling back to Twitter realm, we expose all of them for you to poke at. To get responses from a particular realm, set the Host header (set in .env), for example: curl -H "Host: fxtwitter.com" "http://localhost:8787/user/status/123" Or you can access all realms by their path prefix: /twitter/... FxTwitter / FixupX /bluesky/... FxBluesky /tiktok/... TikTok realm /api/... FxTwitter API /blueskyapi/... FxBluesky API /atmosphere/... Atmosphere API (multi-provider)
