/evm/eth_subscribe

Client invokes `eth_subscribe` to subscribe to a stream of server-pushed events. The first parameter is a subscription-type string; the optional second parameter is a type-specific options object. Ankr does not enumerate accepted subscription-type strings — consult the upstream Ethereum execution-apis spec.

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.
