Posting to Bluesky through the API
Where a lot of tech and indie audiences moved. The request shape is the same one every network here uses — only the limits on this page change.
Bluesky publishes for anyone today. Connect an account and the request below works as written.
Connecting a Bluesky account
Handle + app password. Free, no developer app needed. Once connected, we hold the credential and keep it alive; your code only ever sends the API key.
The limits we enforce before publishing
Caption
300 characters. Over the limit comes back as a 422 before anything publishes.
Media
Up to 4 per post. Media optional.
Video
No video — a video attachment fails pre-flight.
Cadence
20 posts a day per account — the ceiling that stays under Bluesky's spam heuristics.
What pre-flight rejects, verbatim
A request that breaks a Bluesky rule comes back as a 422 naming the network and the number — before anything is scheduled, not after the other networks published. The error strings are these:
432 chars — Bluesky allows 300.6 attachments — Bluesky allows 4.Bluesky does not accept video.
The request
curl -X POST https://attentionpilot.com/api/v1/posts \
-H "Authorization: Bearer $PILOT_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"caption": "Written for Bluesky, under 300 characters.",
"accounts": ["bluesky"]
}'Omit schedule for the next free queue slot, send "now" to publish immediately, or send an ISO timestamp.
When Bluesky fails
Each network is delivered on its own. A revoked token or a rejected upload on Bluesky never blocks your other targets: the post returns "partial", the Bluesky target carries the error text, and you can retry just this delivery.
