Why TextCortex

Build around a common API, not a single model provider.

Choose TextCortex when you want GPT, Claude, Gemini and open-weight models in one API integration. Evaluate EURouter against the catalog, route and request features your application needs.

01

Proprietary and open-weight models

Access GPT, Claude, Gemini, Kimi, GLM, DeepSeek, MiMo and more through TextCortex. Choose models from the catalog available to your account.

02

One OpenAI-compatible API

Use a familiar client, one TextCortex API key and a common base URL. Change the model identifier to switch between supported models.

03

EU-hosted model options

Use EU-hosted routes for European inference requirements. Hosting depends on the selected model and route; the wider catalog also includes other deployments.

Why developers consider a EURouter alternative

EURouter offers a European model gateway. EURouter is another gateway option. Compare model coverage, regional routing, gateway charges and fallback behavior directly. The eurouter.com domain redirects to eurouter.ai.

TextCortex brings proprietary and open-weight model access into a common OpenAI-compatible API. The advantage is the ability to keep one client while selecting models across families and European hosting options.

A broader model choice for your application

Use GPT, Claude and Gemini alongside Kimi K3, GLM-5.3, DeepSeek and MiMo. Select an available model for each request, so your coding assistant, extraction service and support feature can use different models.

For European workloads, choose the EU-hosted route enabled for the model. Broader catalog access does not mean every route has the same hosting location.

Compare the API features you actually use

EURouter is another gateway option. Compare model coverage, regional routing, gateway charges and fallback behavior directly. The eurouter.com domain redirects to eurouter.ai.

Start with the EURouter API comparison guide. Compare streaming behavior, tool calls, reasoning settings, output validation, usage reporting and current rates for your own workload.

Make your first API request

Create a TextCortex account and generate an API key in account settings. Install the OpenAI Python package on your server. Store the key in TEXTCORTEX_API_KEY and set TEXTCORTEX_MODEL to an identifier returned by GET /models.

This example keeps credentials in environment variables. The same client configuration works when you choose another supported model. Read the API reference for endpoint-specific parameters.

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["TEXTCORTEX_API_KEY"],
    base_url="https://api.textcortex.com/v1",
)

for model in client.models.list():
    print(model.id)

response = client.chat.completions.create(
    model=os.environ["TEXTCORTEX_MODEL"],
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)

Move one workload first

Use the migration guide to update your base URL, key and model mapping. Keep the existing integration available while you test a small share of traffic.

TextCortex may use infrastructure providers that also sell inference directly. The comparison concerns the API service and available model routes, not a claim that their underlying infrastructure never overlaps.

Questions

Your next questions, answered.

Is TextCortex limited to open-source models?

No. The API provides access to proprietary model families such as GPT, Claude and Gemini alongside open-weight families such as Kimi, GLM, DeepSeek and MiMo. Use GET /models to list the identifiers available to your account.

What changes when I migrate an existing integration?

Update the base URL, API key and model identifiers. Review provider-specific parameters and test streaming, tools, structured output and error handling used by your application. Keep your original configuration available during the rollout.

Are all models in the catalog EU-hosted?

TextCortex offers EU-hosted model routes and a broader multi-provider catalog. Select the EU-hosted deployment required by your application; catalog membership alone does not establish where a particular request is processed.

How is API usage priced?

Use the rates for your selected model and account. Estimate input and output tokens separately and include any applicable cached-token, reasoning-token or other charges. API consumption is distinct from a workspace subscription.
