Overview

OpenAI-compatible chat-completions inference served on Linkrra's own hardware. Zero data retention: prompts and completions are never stored or used for training. Models available (read live from https://pool.linkrra.com/v1/models): | Model id | Context | Max output | Input $/1M tokens | Output $/1M tokens | |---|---|---|---|---| | `gpt-oss-20b` | 32,768 | 32,768 | $0.0170 | $0.0850 | | `qwen3-coder-30b` | 32,768 | 32,768 | $0.0675 | $0.2700 | | `glm-4.7-flash` | 6,144 | 6,144 | $0.0550 | $0.3800 | Drop-in replacement for the OpenAI Chat Completions API: point any OpenAI SDK at this base URL.

OpenAI-Compatible LLM Chat Completions API FAQs

The POST Create a chat completion endpoint returns a chat completion object, including the model used, generated message content, and usage statistics. The GET List available models endpoint returns a list of models, detailing their IDs, context lengths, and routing information.

Key fields in the chat completion response include "id," "model," "choices" (with message content), and "usage" (detailing token counts). In the models list response, important fields include "id," "owned_by," and "routing."

The chat completion response is structured as a JSON object with nested fields for choices and usage. The models list response is an array of model objects, each containing specific attributes like ID and routing details.

The POST Create a chat completion endpoint accepts parameters such as "model," "messages," and "stream." Users can customize requests by specifying the model ID and providing a sequence of messages for context.

Typical use cases include building chatbots, generating conversational agents, and enhancing customer support systems. The API can be used to create interactive applications that require natural language understanding and generation.

Users can extract the "content" field from the "choices" array to display the generated message. The "usage" field helps track token consumption, which is useful for optimizing requests and managing costs.

Data accuracy is maintained through the use of advanced models trained on diverse datasets. The API operates on Linkrra's hardware, ensuring consistent performance and reliability in generating responses.

If the response contains empty or partial results, users should check the "choices" array for available messages. Implementing error handling can help manage unexpected outputs and ensure a smooth user experience.

General FAQs

To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.

You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.

The free trial lasts for 7 days and allows you to make up to 50 API requests.

No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.

Yes. If the API offers a free trial, you will see a "Free 7-Day Trial" option in its Pricing section. The trial lasts for 7 days and allows up to 50 API requests, enabling you to evaluate the API before subscribing to a paid plan.

Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.

Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world's most reliable payment companies. If you have any trouble paying by card, just contact us at [email protected]

Additionally, if you already have an active subscription in any of these currencies (USD, EUR, CAD, AUD, GBP), that currency will remain for subsequent subscriptions. You can change the currency at any time as long as you don't have any active subscriptions.
The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.
Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]
Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.
API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.
Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.
To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.
To check how many API calls you have left for the current month, refer to the 'X-Zyla-API-Calls-Monthly-Remaining' field in the response header. For example, if your plan allows 1,000 requests per month and you've used 100, this field in the response header will indicate 900 remaining calls.

You can monitor your API usage through the response headers included with every request:

x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.

The 'X-Zyla-RateLimit-Reset' header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3,600, it means 3,600 seconds are left until the limit resets.

Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.

Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.

After 7 days, you will be charged the full amount for the plan you were subscribed to during the trial. Therefore, it's important to cancel before the trial period ends. Refund requests for forgetting to cancel on time are not accepted.
When you subscribe to an API free trial, you can make up to 50 API calls. If you wish to make additional API calls beyond this limit, the API will prompt you to perform an "Start Your Paid Plan." You can find the "Start Your Paid Plan" button in your profile under Subscription -> Choose the API you are subscribed to -> Pricing tab.
