Rate Limits

Limits are per token, with a fixed ceiling across all of an account's tokens so twenty tokens cannot add up to twenty times the budget. GET /me reports the numbers a token is held to.

Class	Sustained	Burst
Reads	300 per minute	600
Review writes	60 per minute	120
Agent messages	30 per minute	60
Whole account	900 per minute	1,800

Over the limit is 429 with a Retry-After header in seconds. A wall screen polling /review every 10 seconds is well inside.

When the limiter itself is down

Reads still proceed, because a read cannot spend money or send anything and a wall dashboard going blank during a blip is the wrong trade. Writes and messages return 503, never a fake pass, because the ceiling they rely on is the thing that broke.
