API Overview

Learn how to call supported Ling and Ring models through ling-1t.ai APIs.

Model API OverviewLink to section

ling-1t.ai exposes RESTful endpoints for calling Ling-2.6-1T, Ling-2.6-flash, and Ring-2.6-1T from your own services. The API surface mirrors familiar OpenAI- and Anthropic-style contracts while enforcing ling-1t.ai authentication and model-specific billing.

Model migration: Ant Ling retired Ling-1T on June 15, 2026. Legacy model IDs return a 400 error and are never aliased silently.

  • Base URL: https://ling-1t.ai/api/v1
  • Authentication: API key issued from the Ling-1T dashboard
  • Models: Ling-2.6-1T, Ling-2.6-flash, Ring-2.6-1T

Model RatesLink to section

  • Ling-2.6-1T: $0.08 input and $0.65 output per million compute units
  • Ling-2.6-flash: $0.05 input and $0.004 output per million compute units
  • Ring-2.6-1T: $0.08 input and $0.65 output per million compute units

Ring-2.6-1T supports adjustable reasoning effort. Use reasoning.effort with the Chat Completions endpoint or output_config.effort with the Messages endpoint. The accepted values are high (default) and xhigh; xhigh can consume significantly more output tokens.

Supported Endpoint FamiliesLink to section

  • Chat Completions (POST /chat/completions): OpenAI-compatible chat API. Supports streaming responses via Server-Sent Events.
  • Messages (POST /messages): Claude-compatible request body/response format. Currently supports non-stream responses.
  • Models (GET /models): Lists the exact model IDs accepted by the API.

HTTP EnvironmentsLink to section

Use HTTPS in production. For local testing, the same routes are available on your development server (e.g., http://localhost:3000/api/v1/...).

Authentication SummaryLink to section

Create API keys in the dashboard and send them with each request:

Authorization: Bearer <api-key>

or for Claude-compatible endpoints:

x-api-key: <api-key>
Anthropic-Version: 2023-06-01

Note: API keys inherit your account’s billing privileges. Rotate keys regularly and revoke unused credentials from the dashboard.

  1. Generate API keys
  2. Call Chat Completions
  3. Integrate with Claude-style clients
