概览

AI 生成的概览

Ephemeral 在隔离沙箱中运行 AI 智能体任务,支持成本上限、已保存工作流、定时计划和受限连接。

可以做什么
  • 创建、查询、等待、列出和取消智能体运行,每次运行都有成本上限和超时
  • 读取运行状态、输出、错误以及最终或暂定的费用
  • 列出、查看、保存和删除可复用工作流,包括其输入与输出结构
  • 列出模型(上下文长度与 token 价格)以及组织已保存的受限连接
  • 列出、查看、创建、修改、暂停、预览、立即运行和删除 cron 定时计划
  • 按 id、名称、大小和类型列出组织已保存的文件
适用场景
适合让助手把任务交给带花费上限的沙箱智能体运行、将其保存为可复用工作流,或按 cron 定时触发。也便于在同一对话中查看运行费用与结果。
运行要求
远程 streamable HTTP 端点 app.ephemer.al,无需本地安装包。不使用 OAuth 登录的客户端需在 Authorization 头中以 bearer 令牌发送 Ephemeral API 密钥,密钥在控制台 Keys 中创建(智能体使用成员密钥)。修改定时计划需要管理员密钥。
安装前请注意
运行会计费到所属组织,取消不会退还未完成工作的费用;计费结算前费用为暂定值。定时计划工具需要管理员密钥,并会启动周期性计费运行。保存或删除工作流与计划会改动组织共享状态,删除工作流会使引用它的计划无法启动。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Ephemeral,将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable,通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

工具

create_run

Create a run

Start an AI agent run in an isolated sandbox and return the run (status queued) at once. Give a prompt, or the name of a saved workflow. Poll with get_run or block with wait_for_run for the result. Every run has a cost cap (max_cost_micros) and a timeout, and is billed to the organization of the API key. Connections must already be saved in the organization; reference them by name. Use idempotency_key to make a retry safe. A run's cost_micros is provisional (usually above the final cost) until cost_final is true; see get_run. On the hosted service a run costs a run fee once its worker starts, compute per second, model calls at the provider's price plus a percentage, and web requests and searches at flat prices; `GET /v1/me` reports the rates.

输入参数webfilesinputmodelshellpromptworkflowconnectionsdescriptioninput_schemaoutput_schemaidempotency_key另有 3 个

get_run

Get a run

Read a run: status, output, error, cost and billing_pending. COST: while billing_pending is true (or the run is still going), cost_micros is PROVISIONAL and usually higher than the final cost; the result then has cost_final:false and a cost_note. Quote a cost only when cost_final is true (the run is finished and billing_pending is false); otherwise call get_run again in a few seconds. For a zero-data-retention run the first read of a finished run returns the output and then deletes it. On the hosted service a run costs a run fee once its worker starts, compute per second, model calls at the provider's price plus a percentage, and web requests and searches at flat prices; `GET /v1/me` reports the rates.

输入参数id必填

wait_for_run

Wait for a run

Wait until a run finishes (succeeded, failed, cancelled, interrupted or timed_out) or the wait ends, then return the run. After the run finishes it keeps waiting, within the same time, until billing has settled (billing_pending false, normally a few seconds to about 20), so the cost is final. Waits at most 60 seconds; if the run is still going, the returned status says so and you can call it again. COST: if the result has cost_final:false, cost_micros is PROVISIONAL and usually higher than the final cost; do not quote it, call get_run again shortly. Quote the cost only when cost_final is true.

输入参数id必填timeout_seconds

list_runs

List runs

List the organization's runs, newest first, with a cursor for the next page. Each run has cost_final: when false, cost_micros is provisional (usually above the final cost) and billing is still settling.

输入参数limitcursorstatus

cancel_run

Cancel a run

Cancel a run that has not finished. Work already done is billed. Cancelling a finished run changes nothing.

输入参数id必填

list_workflows

List workflows

List the organization's saved workflows (reusable run definitions). Each entry has the workflow's name and, when set, its description, input_schema (the shape of the input create_run expects) and output_schema (the shape of the JSON it returns), so you can call a workflow without reading its prompt. Run one with create_run and its name.

无需输入参数。

get_workflow

Get a workflow

Read a saved workflow's definition: description, prompt, model, files, connections, limits and its input_schema and output_schema. Credentials are never included.

输入参数name必填

list_models

List models

Find models. Returns a compact list (id, name, context_length, input and output USD per million tokens, zero_data_retention where known), the total count and the default model. There are hundreds of models, so filter with query (case-insensitive part of the id or name, e.g. "claude", "gpt") and read the hint when the list is truncated (default 25, at most 100). Pass model for one model's full details. Use an id from it as create_run's model.

输入参数idlimitmodelqueryzero_data_retention

list_connections

List connections

The organization's saved connections that a run may use, with type, allowed methods and tools. No URLs or secrets are returned. Reference one in create_run by name.

无需输入参数。

save_workflow

Save a workflow

Create a workflow, or replace the one with this name (saving the same definition again changes nothing more). A workflow is a reusable run definition: start it with create_run and its name, or on a timetable with create_schedule. Connections must already be saved in the organization; reference them by name, never with a URL or a credential. Read the current definition with get_workflow first when you change part of it, because saving replaces the whole definition. Give it a description, and an input_schema and output_schema (JSON Schemas) so that agents can discover and call it: a run's input is checked against input_schema before it starts, and its output must be JSON matching output_schema or the run fails.

delete_workflow

Delete a workflow

Permanently delete a saved workflow. Runs already started are not affected; schedules that use it stop being able to start runs until it is saved again.

输入参数name必填

list_schedules

List schedules

List the organization's schedules: each starts a saved workflow on a cron timetable. Includes the next start, the last run and the last error.

输入参数workflow

get_schedule

Get a schedule

Read a schedule: timetable, time zone, input, cost cap, whether it is enabled, its next start and the outcome of its last start.

输入参数id必填

create_schedule

Create a schedule

Start a saved workflow on a timetable. Needs an administrator key. Each start is a run billed to the organization, with the cost cap given here (or the default). Use preview_schedule first to check the timetable. A schedule pauses itself after repeated failed starts. An organization can have 50 schedules.

update_schedule

Update or pause a schedule

Change a schedule; only the fields you give change. Needs an administrator key. Set enabled to false to pause it and to true to resume it (resuming clears the failures that paused it). A new timetable counts from now.

输入参数id必填cronnameinputenabledtimezoneworkflowmax_cost_microsskip_if_running

delete_schedule

Delete a schedule

Permanently delete a schedule. Needs an administrator key. Runs it already started are not affected. To stop it for a while, pause it with update_schedule instead.

输入参数id必填

preview_schedule

Preview a timetable

Check a cron expression and time zone and return the next five start times (UTC), without saving anything.

输入参数cron必填timezone

run_schedule

Run a schedule now

Start the schedule's workflow now, outside its timetable, with the schedule's input and cost cap. Returns the queued run (follow it with wait_for_run); each call starts another run and is billed like any run.

输入参数id必填

list_files

List files

List the files saved in the organization: id, name, size, content type and creation time. Reference a file by id in a run's or workflow's files. Read-only; upload and delete files through the REST API.
