Every running ework mounting the tier is told, and picks the change up in about twelve seconds. ## OpenAPI ````yaml /openapi.json put /api/v1/eworks/{id}/memory openapi: 3.1.0 info: title: Ergoly platform API version: 1.0.0 description: >- Read and change one organization's own Ergoly environment. Every route is scoped to the organization the presented credential resolves to; there is no parameter that widens it. The human-readable reference is served from the same namespace at `/api/v1/docs`, behind the same credential. The namespace's front door is `GET /api/v1`, and it is deliberately absent from `paths` below. It answers without a credential — what this API is, how an organization admin mints a key, and where the reference lives — so it is the way in to this contract rather than a part of it: it has no scope, takes no parameters, and there is nothing about it for a generated client to call. Every `unauthorized` refusal carries that same URL as `error.docs`. servers: - url: https://control.ergoly.ai security: - orgApiKey: [] tags: - name: auth description: How to present a key, what it is scoped to, and what a 401 means. - name: organization description: Which organization your credential resolves to. - name: workers description: The Slack apps and bot identities in your organization. - name: eworks description: The runtime instances under a Worker — one core, one per bound Client. - name: clients description: The customers a Worker can be scoped to, and how to bind one. - name: channels description: Which Slack rooms a Worker answers in, and who it answers as. - name: tasks description: >- Tasks handed between Workers and people, scheduled jobs, their targets, and their run history. - name: jobs description: How a provisioning run is going — the other half of every 202. - name: memory description: Read and write the memory tiers an ework mounts. - name: connections description: The credentials your agents use, and the hosts they are injected on. - name: webhooks description: Inbound URLs an outside system can POST to, each of which starts a turn. - name: activity description: Your organization's audit feed. - name: usage description: Cost, turn outcomes and a per-day pulse over a window you choose. - name: errors description: The closed set of refusal codes, and what to do about each. paths: /api/v1/eworks/{id}/memory: put: tags: - memory summary: Write a file description: >- Send exactly one of `content` (text) or `contentBase64` (bytes) — decoding bytes as text mangles them silently, so sending neither is refused rather than guessed. `changed: false` means the content was already identical and nothing was committed.

Every failure to authenticate answers one identical 401: "Provide a valid organization-scoped API key or an active session." Each operation names the one scope it is filed under, `:`, where the resource is the first path segment after `/api/v1/`; a key minted today carries all 22 of them. Scopes are RECORDED — on the key and on every audit row — and are not yet enforced: no request is refused for want of one. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
