Agent API (Responses/Agentic Research). When `stream: true`, returns `text/event-stream` with typed events. Each event carries a `type` and `sequence_number`. Event types documented by Perplexity: - response.created - response.in_progress - response.completed - response.failed - response.output_item.added - response.output_item.done - response.output_text.delta - response.output_te

About AsyncAPI

The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.

Browse every event-driven channel on the APIs.io network or compare with the broader Naftiko capability, Agent Skill, and MCP server surfaces of the same providers.
