How do AbstractAPI keys work across different services?

AbstractAPI issues a unique API key for each distinct service (e.g., one key for IP Geolocation, a completely different key for Email Validation). You must insert the API key that aligns with the specific service you want your AI agent to utilize. If you want to use multiple capabilities, you'll need to instantiate multiple servers or swap the keys.

Can my AI agent build a lead list using just a domain name?

Yes. Provide the domain to your agent and ask it to run the company enrichment capability. It will return the full official company name, founded year, employee count, and LinkedIn profile URL, allowing you to quickly qualify accounts before outreach.

How accurate is the Email Validation capability?

Extremely accurate. When your agent calls the Email capability, it doesn't just check the regex formatting. It probes the domain's MX records, runs real-time SMTP handshakes to ensure the inbox exists, and tests against massive databases of known disposable or role-based email addresses (like info@).

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put AbstractAPI to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

AbstractAPI works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put AbstractAPI to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of AbstractAPI, so you can see the experience inside your AI.

It does not authenticate your account with AbstractAPI. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
