Rate limits
urBackend enforces per-IP rate limits to keep the service stable for all projects.
Requests that exceed the limit receive a
429 Too Many Requests response. Design your client to back off and retry after the rate limit window resets.
Storage limits
Files that exceed the limit return
413 Payload Too Large.
Database limits
When your project approaches the database quota, writes may be rejected with
403 Forbidden. Monitor your usage in the Dashboard.
AI session limits
AI features that use urBackend’s platform Groq key are capped per account, per calendar month. The AI Query Builder and the AI Collection Creator (Schema Design) each have their own separate monthly counter.AI Query Builder
AI Collection Creator (Schema Design)
In addition to the monthly cap, each Collection Creator chat session using the platform key is limited to 20 iterations (turns) before you must start a new session. This per-session cap protects platform resources against long, runaway conversations.
Requests beyond either the monthly cap or the per-session iteration cap return
403 Forbidden. Monthly counters reset on the first of the next calendar month (UTC).
To bypass both the monthly cap and the per-session iteration cap, configure a personal Groq API key at the developer or project level. Requests that resolve to a BYOK key are not counted against any platform cap. See BYOK for AI.
