Assessment: An awakeable pauses a handler at no compute cost and resumes it from one HTTP request, with a durable timeout, on a free plan of 100,000 actions a month. Restate sends nothing to the approver, so the Slack message, email or inbox is the builder's code, and the published terms and privacy statement predate the paid plans.

## Facts

- Kind: Model platform · vendor: Restate GmbH · category: Human approval & handoff · legal entity: Restate GmbH · provenance 54/100
- Local only (HTTP): npm `@restatedev/restate-sdk`, pypi `restate-sdk`, npm `@restatedev/restate-sdk-clients`
- Auth: API key · pricing: Freemium · x402: no · licence: BSL 1.1 converting to Apache-2.0 four years after release (server), MIT (SDKs)
- Probe metrics: not measured yet (probes haven't run)
- Ways to run it: Restate Cloud (managed, US or EU region, self-serve), Restate BYOC (managed in the customer's AWS or GCP account, set up with the Restate team) or the self-hosted server, a single binary
- How the answer arrives: `POST /restate/awakeables/<id>/resolve` or `/reject` on the ingress, or `ctx.resolveAwakeable()` from another handler. Signals and workflow promises are resolved from handlers
- Timeouts: Set in code with `orTimeout` on the promise. The timer is durable. No default timeout on an awakeable
- Channels: None built in. The docs name Slack, email and a dashboard as places the builder sends the awakeable ID
- Audit: Each invocation's journal in the UI and by SQL, kept 1 day on Free, 3 on Starter, 7 on Business and 30 on Premium. OTEL export from Business. No record of who resolved an awakeable was found
- Credentials: Restate Cloud API keys (`key_...`) with a role, sent as a Bearer token. ED25519 request signing from Restate to services. None on a self-hosted server
- Free plan: 100,000 actions a month, 10 actions a second with bursts to 100, 1 GB of storage, 1-day history, community support, no card
- Retries: `Idempotency-Key` header on calls and sends with 24-hour retention by default. Retry ingress errors on 408, 425, 429 and 5xx
- SDKs: TypeScript 1.17.2 (21 September 2026), Python 1.0.5 (2 September 2026), Java and Kotlin, Go and Rust, all MIT
- Coding agent tooling: A plugin and skills in restatedev/skills and a docs MCP server at https://docs.restate.dev/mcp. Both cover documentation, not running environments
- Certifications: SOC 2 Type I with a Type II audit under way, per the BYOC docs. HIPAA BAA as a paid add-on from Business
- Prices: Starter plan $75 per month (plan); Business plan $300 per month (plan); Premium plan $1000 per month (plan); Extra durable actions on Starter and Business $0.025 per 1,000 tool calls; Extra virtual object storage $0.50 per GB per month

- Scores: Reliability 91, Performance pending, Schema & documentation 85, Agent ergonomics 81, Security & auth 61, Payments & pricing 40, Task success pending, Maintenance & community 92, Transparency & trust 50 · total over the 7 assessed categories
- Why: Reliability, Graded as Restate Cloud, the hosted service, with the hosted lines. · Schema & documentation, OpenAPI 3.1 for the Admin API, 28 paths, at docs.restate.dev/schemas/openapi-admin.json, and the server generates an OpenAPI 3.1 definition… · Agent ergonomics, No MCP server for operating Restate was found, so the surface is the HTTP ingress and Admin API. · Security & auth, Graded as Restate Cloud. · Payments & pricing, No machine payment protocol (0). · Maintenance & community, Server v1.7.13 tagged on 1 October 2026 and v1.8.0-rc.1 on 2 October (30). · Transparency & trust, Server under BSL 1.1 with a grant for production use other than a public Restate platform service, converting to Apache-2.0 four years after…

## Before you call it

1. Create the awakeable, send its ID inside `ctx.run`, then await the promise, so a retry doesn't send a second approval request
2. Resolve with `POST /restate/awakeables/<id>/resolve` and a JSON body, or `/reject` with a text reason, which throws a terminal error in the handler
3. On Restate Cloud send `Authorization: Bearer key_...` to `https://<env_id>.env.<region>.restate.cloud:8080`. On a self-hosted server put an authenticating proxy in front of port 8080
4. Wrap the wait in `orTimeout` and decide what a timeout means. Without it the handler waits with no limit
5. Retry ingress errors only on 408, 425, 429 or 5xx, and only when `x-restate-error-source` isn't `invocation`
