ENTON documentation

The ENTON API, the Terminal and Code products, and the Davinci research program: what each one does and how to call it.

Overview

ENTON is an autonomous finance engine. The same engine runs enton.ai/terminal, enton.ai/code and the iOS app, and part of it is open to developers through the ENTON API: natural-language queries, trading cards, order placement through your own broker, endpoint discovery and OAuth connections.

New here? Start with the quickstart. Every endpoint has a reference page with its parameters, response, errors and curl, JavaScript and Python samples.

The API

AI queryAsk a financial question in plain English and get an answer with the data behind it.POST /ai/queryTrading intelligenceTrading cards: a direction, price levels, recent news and indicators per symbol.POST /trading/cardsTrade executionPlace an order through your connected broker, with a prepare step and a confirmation token.POST /trading/executeAPI discoverySearch the indexed financial API endpoints in natural language.POST /discoverOAuth serviceList providers, start a broker connection and check its status.GET /oauth/…Health and OpenAPIUptime check and a machine-readable description of every endpoint.GET /health · GET /openapi.json

Base URL

Every endpoint lives under one base URL. Paths on the reference pages are shown in full.

Base URL
https://enton.ai/api/v1

Requests and responses are JSON. Authenticate with an API key as a bearer token; see authentication. The API needs an active Trader or Partner plan.

OpenAPI

GET /api/v1/openapi.json returns the API as an OpenAPI 3.1 document, generated from the same source as these pages. Import it into Postman or Insomnia, or generate a client from it.

Known issues

Known issue

3 endpoints currently fail with 401 after your key is accepted: POST /trading/cards, POST /trading/execute and GET /oauth/{provider}. Each one forwards to an internal route that expects a signed-in session. Their pages say more, and the changelog will record the fix.
