# A compatible AI API with visible request paths

Source: https://cicora.ai/en/products/api

Connect with OpenAI-compatible endpoints or Anthropic Messages using API keys and request-level usage.

Keep a familiar request shape while you select a public model identifier and manage access with platform API keys.

## Connect through the interface your tool expects

- Send OpenAI-compatible chat completion requests.

- Use the Anthropic Messages-compatible endpoint.

- List models and inspect usage by request and API key.

## From key to request record

Create a key, choose a public model identifier, send a compatible request, then review the resulting usage record.

## For developers, tools, and internal integrations

Use the API when an application or coding tool needs a compatible chat, image, or Messages interface.

## Compatibility is not a model guarantee

Endpoints accept compatible request formats, but available models and capabilities follow the current public catalog.

## Continue with integration details

### Where do I find the correct base URL?

Use the setup guide for your client: OpenAI-compatible clients use the API root, while Claude Code uses its Anthropic-compatible root.

### How should I handle an API key?

Store the key in a trusted server environment. If it is exposed, revoke it and create a replacement; never send the full key to support.

### Does the API support Responses?

The Responses API is published. Before integrating, check the Responses guide for supported models, parameters, streaming and compatibility limitations.

### When is it safe to retry?

Retry transient failures with bounded backoff only before output begins. Retrying after output starts can duplicate work and confirmed usage.

## FAQ

### What is cicora.ai?

cicora.ai is a multi-model AI workspace and compatible API for chat, text, images, video, coding tools, and teams. Start with the [overview](/en.md), [documentation](/en/docs.md), or [model catalog](/en/models.md).

### How is usage billed?

Confirmed usage is charged in USD from the active workspace's prepaid balance. Use the live catalog for current model prices and the [usage guide](/en/docs/usage-costs.md) for settlement details.

### Which protocols and integrations are available?

Documentation covers OpenAI-compatible Chat Completions and Responses, Anthropic Messages, image interfaces, Claude Code, OpenCode, and Codex CLI. Compatibility does not imply support for every upstream parameter.

### Which sources are authoritative and current?

For model IDs, availability, capabilities, limits, and prices, use the [live catalog](/en/models.md). For API behavior, use the matching [documentation page](/en/docs.md). Never include API keys, private workspace data, or preview URLs in public documents.
