242 servicesChat Completion with Qwen3.8 Flash 27B
Generate text with Qwen3.8 Flash 27B. JSON chat completions, model discovery, and usage-based metering for coding and text workflows.
FlonnoRandom Trivia, Quotes & Life Hacks API

SkycraftVerifiedCreate, Validate & Parse E-Invoice API
Create ZUGFeRD, XRechnung, or Peppol e-invoices, validate XML or PDF documents, and extract invoice data, totals, and rule errors.
Callable LabsGenerate Image Foreground Mask API
The Image Mask API finds the main subject in an image and returns a grayscale mask of it. Use the mask to composite, clean up edges or analyse the subject in your own pipeline. Send the image in image, as a public URL or base64 data, up to 20 MB. Set format to json (default) or png. JSON returns the mask as a data URI with its metadata. PNG returns the mask file. Set quality to best (default) or fast. Set crop to true to trim the mask to the subject, with padding (0 to 1000 pixels) of space around it. Use maxsize to limit the output size. The JSON response includes the width, height, bytes, the subject bbox in the original image and the foregroundratio, the share of the image covered by the subject. If no subject is found, bbox is null. Teams use the Image Mask API to build cutouts for product photos and to place subjects on new backgrounds in their own editor. Others check that an upload has a clear subject, or crop images to it. To get the cut-out subject instead of the mask, use the Remove Image Background with Advanced Controls API. To read text from images, use the Image & PDF OCR to Markdown API.
Callable LabsDomain Pricing, TLD & Registrar Information
Domain availability API that checks up to 100 names per call, compares TLD prices across registrars, and returns WHOIS, DNS, SSL and uptime data.
tldersFood Search & Trivia API
Search food content, classify food images, and get food chatbot responses. Returns recipes, videos, trivia, jokes, and structured search results.
SkycraftVerifiedWine Pairing & Recommendations API
Wine pairing API that suggests wines for a dish and dishes for a wine, with descriptions and rated wine picks you can filter by price. Free tier, no card.
SkycraftVerifiedWorld News API
Search, extract, and retrieve news articles by URL, IDs, or source filters. Get titles, authors, summaries, publish dates, sentiment, and links.
SkycraftVerifiedChat Completion with Qwen3-Next-80B
Chat Completion generates replies from a conversation, with the same request and response shape as the OpenAI Chat Completions API. Send a messages array of system, user, and assistant turns with model set to qwen3-next-80b, and the generated reply comes back in a single synchronous call. There are no job IDs and no polling. You can tune each call with maxtokens (default 512) and temperature (0 to 2, default 0.7). The reply is in choices[].message.content. The finishreason field is stop or length, so you can tell when output was cut off. A usage object gives prompt, completion, and total token counts for tracking consumption. Use it for chatbots and conversational agents, drafting and rewriting copy, summarising short text, Q&A over content you pass in, and other general language tasks. Note: Upgraded 2026-10-05 — this endpoint now runs on Qwen3-Next-80B-A3B-Instruct (Apache 2.0), a substantially larger and more capable model than the previous Ministral-7B backend. The endpoint, request format, and model value (mistral-7b) are unchanged for backward compatibility. Typical response time is a few seconds, depending on max_tokens.
MasterA AIVerifiedGameBrain API
Search games, fetch detailed metadata, find similar titles, and load game news. Useful for catalogs, recommendations, autocomplete, and editorial tools.
SkycraftVerifiedDiagram, Math and Code Render API
Render Mermaid, Graphviz, D2 and Vega-Lite diagrams, LaTeX math and highlighted code to PNG, SVG or PDF with one API call. Free tier on ApyHub.
Callable LabsDecode QR & Barcode API
Decode QR codes and barcodes from an image URL or base64 payload. Returns decoded text, format, position, and parsed payloads when available.
Callable LabsWhich Model API do you need?
The question you arrived with, and the API that answers it.
What is the Model Kit?
The Model Kit is the model layer of your product: chat, reasoning, summarization and classification through one consistent interface across providers.
You choose the right model per task, compare cost and quality, and move fast when the market shifts, without rebuilding integrations each time.
How AI products use it
- Send chat to one provider and summaries to another, through the same interface.
- Switch providers when price or quality changes, without rewriting code.
- Add new models as they launch while your integration stays the same.
Why not build it in-house?
Each capability in the Model Kit looks simple to build. The hard part is keeping it accurate, available and up to date once your product depends on it.
- Provider integrationsEach LLM provider has its own SDK, auth, error codes and rate limits. Every one you add is another integration to keep current.
- Model churnNew models launch and old ones are retired every few months. Each switch means re-testing prompts, outputs and costs across your product.
- Outages and rate limitsWhen a provider slows down or goes down, your product does too, unless you have built retries, fallbacks and quota handling yourself.
- Cost trackingToken prices differ per model and change often. Knowing what each feature costs you needs metering you have to build and maintain.
Do you run an API that belongs in the Model Kit?
Publish it on ApyHub and put it in front of the teams and AI agents building with the Model Kit. Your API joins the catalog under one subscription, becomes callable through MCP, and earns from every call.
Questions about the Model Kit
What is the ApyHub Model Kit?
The Model Kit is the model layer of your product: chat, reasoning, summarization and classification through one consistent interface across providers.
What is an LLM API?
An LLM API lets your software send prompts or chat messages to a large language model and receive generated text back. It is how AI products add chat, summaries, classification and agent reasoning.
Is the Model Kit OpenAI-compatible?
Yes. Chat Completion Generation follows the OpenAI chat format, so code written for OpenAI-style chat completions works with minimal changes.
Can I choose the model provider per request?
Yes. You choose the provider on each request, so you can route different tasks to different providers and switch when price or quality changes.
When should I use the advanced chat completion API?
Use Advanced Chat Completion Generation when you need tools, streaming, web search or structured output. Use Simple Chat Prompt for a single prompt and response.
Can I test Model Kit APIs before integrating them?
Yes. Every API has a Try it panel on its service page. Your key is filled in, you send a real request and see the actual response in your browser before you write any code.
Can AI agents use the Model Kit?
Yes. Every endpoint is MCP-ready. Connect ApyHub MCP to Claude, ChatGPT, Cursor, Mistral Le Chat or any MCP-compatible agent, and your agent can discover and call these APIs directly.
How is it priced?
Every kit sits under one subscription, paid in atoms, ApyHub's usage unit. Every call shows its cost, and the free Starter plan needs no card.
