Highlights

• New AgentClient in the Python, TypeScript, and Rust SDKs for calling one agent through the Agent Execution API with an agent key (EVERRUNS_AGENT_URL / EVERRUNS_AGENT_KEY). It covers run(), sessions, events and SSE streaming, cancel, questions, tool approvals, runtime tokens, for_end_user, and idempotency keys. The management client is now deprecated in favor of AgentClient.
• Change reasons: all SDKs gain with_reason / withReason, a derived client that sends the Everruns-Change-Reason header so the server records the reason in entity change history.
• The default base URL is now Everruns Cloud (https://app.everruns.com/api) instead of a placeholder, so a client created with only EVERRUNS_API_KEY works. EVERRUNS_API_URL still overrides it for self-hosted.
• Docs: how to connect an AG-UI client to an Everruns endpoint.
• OpenAPI examples no longer name the sunset Claude Sonnet 4.5.

• Everruns SDKs default to the Everruns Cloud API URL
• Everruns SDKs record why a change was made
• Everruns SDKs add AgentClient to call one agent with a key

from everruns_sdk import AgentClient

agent = AgentClient()
print(await agent.run("What is the status of order 42?"))

Calling an agent through the management client’s sessions.create and messages.create still works but is deprecated: Python warns once, and TypeScript marks the methods @deprecated.

See Call your agent from code, SDKs and #116.

await client.with_reason("retire the unused agent").agents.delete("agent_123")

The server rejects a reason longer than 1000 characters, one with control characters other than newline and tab, or one that looks like a credential, with HTTP 400 invalid_change_reason.

See Change history, SDKs and #115.

Self-hosted deployments keep pointing the client at their server with EVERRUNS_API_URL:

export EVERRUNS_API_URL=https://everruns.example.internal/api

See SDKs and #114.

everruns-sdk = { version = "0.2", default-features = false, features = ["native-tls"] }

On a minimal client that creates a session and streams events, a stripped release build is 6.5 MiB with rustls-tls and 3.0 MiB with native-tls. Leaner tokio, futures and reqwest feature sets also trim the default build, and the SDK moves to reqwest 0.13.

See SDKs, #110 and #109.

Highlights

• Rust SDK footprint trimmed for consumer binaries: leaner tokio/futures/reqwest feature sets, and TLS is now a Cargo feature (default rustls-tls, or native-tls for a much smaller binary).
• Rust SDK upgraded to reqwest 0.13.
• Dependency and security updates across all SDKs.
• Documentation polish: Everruns logo in the README, plainer punctuation in prose.

• Everruns Rust SDK can use native TLS for smaller binaries
