Authentication errors right now for sprites

We’ve been using a lot of sprites the last week and they have been a little unreliable. Getting errors here and there that usually a retry fixes. However, right now none of our requests are going through. They all say “authentication failed” and I’m wondering if something got blocked for my account.

Some things I’m noticing

  • Both read and write options fail identically with 401
  • Freshly generated token (using sprite util on my machine) still fails
  • TLS and connectivity are fine, seems linked purely to auth
  • Server version: Fly/9e304e1bc (2026-03-11)

Request (GET - list sprites):

GET /v1/sprites?max_results=1 HTTP/2
Host: api.sprites.dev
Authorization: Bearer <org>/<id>/<redacted>/<redacted>
Content-Type: application/json
Accept: application/json

Response:

Hello @nathanpalmer! Sincere apologies for the recent experience with your Sprites operations.

The team has rolled out a patch for the underlying issue causing 401 errors with Sprites operations for certain organizations. Could you please check if you’re now able to run operations successfully?

Yeah, seems to be working now. That was quite a long outage. Thanks.
