Linkworld Platform

Agentic features in your product.
EU-sovereign. No rewrite.

Add agentic features to your product without operating your own AI infrastructure: point your existing OpenAI client at Linkworld — no rewrite, no new SDK — and it runs on EU-sovereign, multi-LLM infrastructure with tenant isolation, per-tenant usage metering, an approval layer in front of every high-stakes action, and a complete audit trail.

Early access · key issued in your workspace · starter quota included · no sales call required

Multi-LLM, no lock-in

Best model per task — Claude, GPT, Mistral, open source. Provider outages fail over automatically.

Tenant isolation + metering

Every tenant runs isolated; all usage is metered per tenant — billing-ready for your business model.

Approval layer built in

A security gate in front of high-stakes actions: payments, outgoing mail, data access — only after approval.

EU operations, auditable

EU data centers, GDPR-native, EU-AI-Act-ready. Every action logged in a structured, exportable way.

Platform API · Sovereign models

EU-sovereign LLMs. Per token, on demand.

Open models, operated EU-sovereign under our control — including the best reasoning models, always in their latest version. Create an API key in your workspace, start building, billed per tenant. Frontier models run through the same router.

Always the latest model version — upgrades automatic · metered per tenant to the second · volume tiers from 100M tokens/month

Batch: non-urgent bulk jobs via /v1/batches at ~half price — we pass the provider batch discount straight through.

Managed RAG & embeddings

Text and PDF documents in, answers out: the platform handles extraction, chunking, embeddings and the index — isolated per tenant, via /v1/rag.

Create API key

Early access: API keys right in your workspace · starter quota included

Your OpenAI client already works.

The API is OpenAI-compatible: swap the base URL, drop in a key — and your existing code talks to sovereign EU models. No new SDK, no migration.

◦ ◦ ◦   client.py
from openai import OpenAI

client = OpenAI(
  base_url="https://api.linkworld.ai/v1",
  api_key="rk_live_…",
)

client.chat.completions.create(
  model="gpt-oss-120b", …
)

Personal data never touches a non-EU model.

Every call carries its intent: tier picks the model class, contains_pii arms the PII gate — enforced centrally, every model choice logged as evidence for EU-AI-Act audits. The default path stays EU end-to-end, with no US processor; frontier models are a deliberate, logged opt-in for tasks without personal data.

◦ ◦ ◦   policy
"tier": "eu-sovereign"
→ default: EU backend, provider-independent

"contains_pii": true
→ PII gate: forces an EU-sovereign model

"tier": "frontier" + "contains_pii": true
→ 403 policy_violation — blocked centrally, logged

Headless · Platform API

Your product. Our runtime.

You're building a SaaS product and want to ship agentic features — without running agent infrastructure yourself. Your software consumes Linkworld headless: your customers only ever see your product. Metered and billed per end customer.

One tenant per end customer

Isolated data, credentials, audit trail and usage numbers — per customer of your product.

Tools stay on your side

Agents work with your domain APIs via MCP — the business logic stays in your product.

Approval & audit included

The approval layer and audit log apply headless too — configurable per end customer.

◦ ◦ ◦   api.linkworld.ai
POST /v1/agents/{agent}/invocations
→ agent run inside your end customer’s tenant, SSE streaming

PUT  /v1/tenants/{customer}/mcp-bindings/crm
→ your domain API becomes this tenant’s MCP tool

GET  /v1/tenants/{customer}/usage
→ metering per end customer, billing-ready

Platform API · tenant-scoped

MCP-native

Your systems speak MCP.

The Model Context Protocol isn’t an add-on here — it’s how agents reach tools, yours and ours alike.

Domain APIs as MCP bindings

Attach your CRM or ERP per tenant as an MCP tool — agents use it like a platform tool, scope-gated.

Every app speaks MCP

Apps reach platform tools via MCP with skill gating: the agent only sees what the tenant is entitled to.

Your coding agent connects

Claude Code, Cursor & co. connect directly to the platform — lint, deploy and test console as MCP tools.

The architecture

One runtime. Every layer.

From UI to isolated execution: your apps and products sit on top — everything underneath is Linkworld.

Frequently asked

Before you integrate.

Do I need to rewrite my code to use the Platform API?

No. The API is OpenAI-compatible — you just swap the base URL and key, and your existing code keeps running unchanged. No new SDK, no migration.

Where are the models that run behind the Platform API operated?

EU-sovereign, under our control — including the best reasoning models, always in their latest version. Frontier models like Claude, GPT or Gemini run through the same router.

What happens if a call contains personal data?

The PII gate enforces an EU-sovereign model centrally. Combining the "frontier" tier with contains_pii is blocked with a 403 policy_violation and logged — evidence for EU-AI-Act audits.

How is usage billed?

Per token and per tenant, metered to the second. Volume tiers apply from 100M tokens/month; non-urgent bulk jobs run through /v1/batches at roughly half price.

Can I use retrieval (RAG) through the API too?

Yes — managed RAG via /v1/rag handles extraction, chunking, embeddings and the index, isolated per tenant. Only embedding tokens, vector storage and queries are billed.

Can my own domain APIs talk to the agents?

Yes, via MCP. You attach your domain API per tenant as an MCP tool, and the agent uses it scope-gated like a platform tool — the business logic stays in your product.

Is the Platform API generally available yet?

It's currently in early access: the API key is issued right in your workspace, with a starter quota included and no sales call required.

Start right now.

No framework agreement, no sales cycle: request an API key and get your starter quota through early access. As your volume grows, the tiers grow with you.
