api reference

about

typesafe's system one model. send a state and typed questions (choice, score, noul); get calibrated, structured answers your code can act on directly.

1. calling the api

install the client

the client provides a convenient way to interact with the api.

bash
1pip install inferencesh

setup your api key

set INFERENCE_API_KEY as an environment variable. get your key from settings → api keys.

bash
1export INFERENCE_API_KEY="inf_your_key"

run and get result

submit a request and wait for the final result. best for batch processing or when you don't need progress updates.

python
1from inferencesh import inference23client = inference()456result = client.run({7        "app": "typesafe/jev",8        "input": {}9    })1011print(result["output"])

stream live updates

get real-time progress updates as the task runs. ideal for showing progress bars, partial results, or long-running tasks.

python
1from inferencesh import inference23client = inference()456# stream=True yields updates as they arrive7for update in client.run({8        "app": "typesafe/jev",9        "input": {}10    }, stream=True):11    if update.get("progress"):12        print(f"progress: {update['progress']}%")13    if update.get("output"):14        print(f"output: {update['output']}")

2. authentication

the api uses api keys for authentication. see the authentication docs for detailed setup instructions.

3. files

file inputs are automatically handled by the sdk. you can pass local paths, urls, or base64 data.

automatic upload

the python sdk automatically detects local file paths and uploads them. urls are passed through as-is.

python
1# local file paths are automatically uploaded2result = client.run({3    "app": "typesafe/jev",4    "input": {5        "image": "/path/to/local/image.png",  # detected & uploaded6        "audio": "https://example.com/audio.mp3",  # url passed through7    }8})

manual upload

you can also upload files manually and use the returned url.

python
1# upload and get a hosted URL2file = client.files.upload("/path/to/file.png")3print(file.uri)  # https://cloud.inference.sh/...

4. webhooks

get notified when a task completes by providing a webhook url. when the task reaches a terminal state (completed, failed, or cancelled), a POST request is sent to your url with the task result.

python
1result = client.run({2    "app": "typesafe/jev",3    "input": {},4    "webhook": "https://your-server.com/webhook"5}, wait=False)

webhook payload

your endpoint receives a JSON POST with the task result:

json
1{2  "id": "task_abc123",3  "status": 9,4  "output": { ... },5  "error": "",6  "session_id": null,7  "created_at": "2024-01-15T10:30:00Z",8  "updated_at": "2024-01-15T10:30:05Z"9}
idstring— task id
statusnumber— terminal status (9=completed, 10=failed, 11=cancelled)
outputobject— task output (when completed)
errorstring— error message (when failed)
session_idstring— session id (if using sessions)
created_atstring— iso timestamp
updated_atstring— iso timestamp

5. schema

input

stateany*

the content to evaluate: a string, or a json object / array of related context (messages, records, a policy). text only. every question sees the same state. send only what the questions need; unrelated detail costs accuracy.

example: "Our API started returning 500 errors 20 minutes ago and we can't process any customer orders."
choicesarray

choice questions: pick one option from a set.

scoresarray

score questions: place the state on ordered levels.

noulsarray

noul questions: probability that the answer is yes.

modelstring

model name or alias: `jev-latest`, `jev-preview`, or a pinned version such as `jev-1.13.0`. pin a version if you tuned thresholds against it.

default: "jev-latest"

output

choicesobject

choice answers by question id.

input_tokensinteger

input tokens (billed).

modelstring*

the versioned model that answered, e.g. `jev-1.13.0`.

noulsobject

noul answers by question id.

output_tokensinteger

output tokens (free upstream).

scoresobject

score answers by question id.
