APIVerve

One contract for your whole stack.

The cost of an integration isn't the first call — it's the tenth vendor with its own auth, its own response shape, and its own outage page. APIVerve collapses that into one key and one predictable contract, with SDKs and an MCP server so every service in your stack talks to the catalog the same way.

Outcomes

Integrate once, reuse everywhere

One key, one auth model

Every endpoint uses the same authentication and the same envelope — learn it once, use it across services.

SDKs and an MCP server

Official libraries and a Model Context Protocol server mean your apps and AI agents integrate the same catalog.

Dependable by contract

A 99.9% uptime SLA, a public status page, and usage alerts keep your integrations observable and reliable.

How it works

Connect APIVerve to your stack

  1. 01

    Authenticate once

    Issue a key (and scoped sub-keys for teams) and use the same auth header across every endpoint.

  2. 02

    Call from anywhere

    Use an official SDK, a raw HTTP request, or the MCP server for AI agents — the contract is identical.

  3. 03

    Monitor and scale

    Watch usage in the dashboard, subscribe to status, and rely on the SLA as your integration grows.

System integration questions.

Answers to the questions teams ask before they build.

Talk to the team →
What does one unified key actually change?
Instead of managing separate accounts, auth schemes, and response formats per vendor, you integrate once against a single key and a single response envelope — then reuse that pattern for every API in the catalog.
Do you offer SDKs and an MCP server?
Yes. There are official SDKs for popular languages, and an MCP server that exposes the catalog to AI agents like Claude, Cursor, and Windsurf. See the docs and the MCP page for details.
Can I scope access for different teams or services?
Yes. Sub-keys let you issue scoped credentials per team, service, or environment while keeping billing and usage under one account.
How reliable is the platform for production integrations?
APIVerve runs on Google Cloud with a 99.9% uptime SLA on higher plans, a public status page, and usage alerts — so your integrations stay observable and dependable.

Build it on one key. Every API here shares one contract, one bill, and a 99.9% uptime SLA.
