API-First
API-first describes software where every capability is exposed through an API. In plain terms, the API is a universal door that lets software reach every piece of data in the system: sites, meters, emission factors, reports, all of it. When a platform is built this way, an AI agent can walk through any door and do broad, general work on your behalf.
In an API-first platform, the user interface and any AI agents both sit on top of the same API. Anything a person can do by clicking, software can do by calling the API. This is an architectural decision made early: the platform is built as a set of programmable capabilities first, with screens layered on top.
The alternative is a platform where the API was bolted on later and only covers part of the system. On those platforms, vendors are forced to wire shortcuts onto an existing product and call each one an "agent." The result is a bundle of narrow tricks, not an assistant that can run with a task. Each shortcut works, but only on the specific task it was wired for.
This is why API-first matters when evaluating AI agents. An agent is only as capable as the surface it can reach. A useful question to ask a vendor: can the agent reach any part of the data model, or only certain screens? On an API-first platform like Gravity, agents can do broad, general work because every part of the system is accessible to them, with the same permissions and audit controls that govern human users.
Frequently asked questions
What does API-first mean? +
API-first means every capability of a software platform is exposed through an API, so anything a person can do in the interface, software can do programmatically. The API acts as a universal door to all data and functions in the system.
Why does API-first matter for AI agents? +
An agent is only as capable as the surface it can reach. On an API-first platform, an agent can reach any part of the data model and handle broad, general work. On platforms without full API coverage, agents are limited to the narrow tasks they were wired for.
How can I tell if a platform is API-first? +
Ask the vendor whether the agent can reach any part of the data model or only certain screens, and whether the platform was built to let software safely do the work. A vendor with a real API-first architecture can answer with confidence and show you.

AI Agent
An AI agent is software you can hand a task to and reasonably trust to carry it out, flag what's unclear, and tell you when it's done. Unlike chatbots or copilots that respond to prompts one message at a time, an agent works in the background across an entire task, using the platform's tools and data, and stops for human approval at defined gates.
AI Skill
An AI skill is detailed written guidance that an agent reads before doing a specific kind of task, including both instructions and context. Skills are reusable expertise: created and validated by human subject matter experts, applied automatically by the agent whenever the task calls for them.
AI in Carbon Accounting
AI in carbon accounting refers to the application of artificial intelligence — including machine learning, natural language processing, and agentic workflows — to automate data collection, classify emission sources, match emission factors, detect anomalies, enrich supplier data, and generate disclosure-ready reports with reduced manual effort.
