accountSubscribe

Subscribe to changes for a single Solana account. Notifications are emitted when the account's lamports or data change at the configured commitment level. Helius's accountSubscribe is "enhanced" on Helius WS — it accepts the standard Solana parameters and runs on the same unified endpoint as transactionSubscribe.

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.
