Context
Bring the right business data into each request.
SMART APIs
Your API can do more than return data.
Smart APIs add context, decisions, validation, evidence, and controlled actions to ordinary API calls. Use ours, or add the same intelligence layer to an API you already run.
THE IDEA
Keep the API. Add the intelligence it needs.
A Smart API starts with a normal, predictable API contract. Then you choose the capabilities that make that endpoint more useful for your application, team, or agent.
You can keep deterministic application rules where they belong while using intelligence for the parts that benefit from context, judgment, ranking, or research.

INTELLIGENCE MODULES
Add only what the endpoint needs.
Smart APIs are modular. A high-volume classifier should not carry the same cost or complexity as a research or work-execution endpoint.
Decisions
Route, rank, classify, score, or choose from allowed options.
Validation
Check outputs against schemas, policies, evidence, or quality rules.
Evidence
Return source and receipt metadata alongside the result.
Orchestration
Coordinate multiple data sources, APIs, or tools behind one contract.
Actions
Perform explicitly authorized work when the API is allowed to act.
SMART API CATALOG
Use a product. Combine products. Build your own.
Start with one bounded capability and expand as your application needs more context or authority.
Smart Notion API
Search, resolve, query, reconcile, and safely operate Notion without hard-coding workspace structure.
Decision APIs
Add fast routing, ranking, classification, and abstention decisions to software and agents.
Smart Research API
Turn a research question into structured findings with evidence and source controls.
Smart Work API
Plan, review, reconcile, and execute bounded work through a typed API contract.
SEO Opportunity API
Combine search and site data into a prioritized next opportunity.
Smart API Upgrade
Add intelligence to an API you already have without rebuilding the underlying service.
SMART API UPGRADE
Already have an API?
Bring an existing endpoint or OpenAPI definition. Add selected intelligence modules around it while preserving the contract your software already uses.
Keep your upstream service. The intelligence layer can sit in front of what already works.
Choose the modules. Add routing, context, validation, evidence, model selection, or controlled actions where they create value.
Control failure behavior. Decide whether an uncertain enhancement should abstain, request review, or return the base API result.
Measure every call. Track usage, latency, errors, provider cost, and receipts from the same portal.
FOR PEOPLE AND AGENTS
One product, multiple ways to consume it.
Use account-based API keys for applications and teams, or machine-native payment for compatible agent workflows. Smart APIs can also be exposed through MCP, SDKs, batch jobs, or webhooks when the product calls for it.
Every Smart API defines
- what it accepts and returns;
- which data it may use;
- what happens when confidence is low;
- what it is and is not allowed to do;
- what evidence comes back with the result;
- how usage and cost are measured.
GET STARTED
Build with a Smart API.
Create an account to provision API access, or start with Smart Notion if you want an intelligent data and operations layer over a Notion workspace.
