The request is malformed, or its schema refuses it: an unknown
property, a value of the wrong type or outside its bounds, a limit
above 200, or a sort outside the operation’s allow-list (Problem
type bad-request). errors names each field by its path, such as
nested.note, or $ for the body itself. The request is refused
before anything is read or written. A cursor that was altered, has
expired, or was issued for other filters, another sort, organization,

about the caller’s own token, client, or role:
insufficient-scope when the token’s scopes (or an MCP grant’s) lack
the operation’s scope, with WWW-Authenticate: Bearer error="insufficient_scope", scope="..." (RFC 6750) naming the missing
scopes; client-not-allowed when the operation doesn’t admit the
caller’s kind of client, such as a machine client calling a user-only
operation; and insufficient-role when a confirmed member’s roles
don’t allow the action. Any other refusal is the generic forbidden,
which says nothing more. Another organization’s resource is 404
(not-found) instead, so no reason confirms that it exists. An owner
or administrator who sent no proof of a second factor gets
mfa-required. An operation
that needs an active subscription, when the organization has none,
returns subscription-inactive, or organization-suspended when
Fedwright suspended the organization. A suspended
organization also refuses invitations, new joins through an
invitation, and role changes with organization-suspended. Creating
or joining
an organization without a verified email returns email-unverified,
and accepting an invitation sent to another address returns
invitation-email-mismatch. A request from Fedwright’s web or mobile
app whose session acts for no organization yet returns
organization-required, except on getMe, createOrganization, and
acceptInvitation. Shared data needs the acting organization’s own
subscription; another organization’s doesn’t count.

organization’s burst, daily, and monthly quotas, which all its machine
clients share; there is no client quota. A 429 comes in two shapes
with two header families, so read the response by what it carries.
A machine client’s calls can get a 429 with an empty body. It
has three headers: X-RateLimit-Limit, the
exhausted rule’s limit and window, such as 3000, 3000;w=2592000;
X-RateLimit-Remaining, what is left in that window (0 on a 429);
and X-RateLimit-Reset, the seconds until that window resets. It has
no Retry-After, no RateLimit headers, no Problem, and does not
name the quota. Read the quota from the window w:
w (seconds) |
Quota |
|---|---|
| 60 | Burst. |
| 86400 | Daily. |
| 2592000 | Monthly (the calendar month is reported as 30 days; X-RateLimit-Reset is exact). |
Wait X-RateLimit-Reset seconds before you retry. Refused requests
still count: a client that keeps calling after a 429 keeps adding to
the counter, so it does not regain budget inside the window. A tier
change takes effect within 10 minutes (checkout, the billing portal,
and grants alike), once the client gets a new access token.
Every other 429 has a Problem and Retry-After. The Problem type
is rate-limited for a used-up quota, or, for an ask, ai-budget-exceeded
or premium-quota-exceeded (below). On rate-limited, Retry-After is
the seconds until the used-up limit’s window resets, the latest if
several are. The Problem also carries limit, the quota that is used
up (the one that resets last, if several are), resetsAt, when it
starts again, and traceId. RateLimit-Policy and RateLimit describe only the
caller’s own limits, here and on every other response a limit applies
to. A request refused with rate-limited uses no quota. One
refused after that check, for its scope, role, subscription, or kind of
client, still counts, so once a quota is used up such a request gets
429 instead of its 403. A request that fails authentication is
not counted. An ask that the organization’s
AI spending budget can’t cover returns ai-budget-exceeded instead,
with Retry-After at the end of the budget’s window: that budget
counts what asks cost, not how many there are. An ask that the
organization’s premium units for the day can’t cover returns
premium-quota-exceeded, with limit (org-premium-day), resetsAt
(the next midnight UTC), and Retry-After. That is the plan’s
allowance: a plan with no premium units never covers an ask, and a
higher plan may. A refused ask uses no units.

The caller’s rate limits, in the IETF HTTPAPI RateLimit header fields:

Seconds to wait before retrying.
On a 429 with an empty body (and on the successful responses that carry
these headers), the exhausted rule’s limit and window w in seconds,
such as 3000, 3000;w=2592000. The window names the quota: 60 is burst,
86400 is daily, and 2592000 is monthly.
