Definitions for every term used across the docs.
Terms
| Term | Definition |
|---|---|
| Gateway | A signed endpoint. One URL = one gateway. Each has its own filters, target URL and configuration. |
| Mechanical filters | Rate limiting, deduplication and token budget. Always-on filters. |
| Message unification | Debounce rapid-fire messages into a single payload. Builder plan and above. |
| Keyword routing | Route messages to different endpoints based on keyword matches. Builder plan and above. |
| Quarantine | Where blocked messages live. Reviewable and replayable from the dashboard. Expires based on plan retention. |
| Security envelope | Optional mode: blocked messages are delivered with a security section instead of being quarantined. |
| Blacklist | Per-gateway list of user_id values rejected before any filter runs. |
| Delivery envelope | The _portarus object appended to every delivered payload. Contains status, language, trace id and filter results. |
| Trace id | Unique identifier for each request. Returned in the X-Trace-Id header and in the envelope. Include it in support requests. |
| Bypass | When quota is exceeded or the gateway is paused, messages skip the filters and go directly to your endpoint. |
| Fail-open | If infrastructure is degraded, the message is delivered anyway with the failure recorded. Your agent is never blocked by Portarus. |
