AI infrastructure
APIs for AI Agents
Most agents can reason. Few have structured access to customer, product, and operational data. API Butler closes that gap in minutes.
CSV → agent-ready API
GET /v1/apis/customers?filter[status]=active&limit=25
{ "data": [{ "id": "C-1042", "name": "Acme Corp", "tier": "enterprise" }], "total": 847 }
Product validation
Build Product Prototypes with Real APIs
Skip the backend sprint. Upload CSV, get a live API, and validate startup MVPs and SaaS concepts with real data flows.
Idea -> CSV -> API -> prototype
GET /v1/apis/mvp-data?limit=25
{ "data": [{ "id": "MVP-01", "feature": "onboarding", "status": "testing" }], "total": 48 }
Sales & operations
CRM API from Spreadsheet
Turn customer and lead spreadsheets into live REST endpoints for dashboards, portals, and AI-built CRM tools.
CRM CSV → hosted GET API
GET /v1/apis/crm-leads?filter[stage]=qualified
{ "data": [{ "company": "Acme Corp", "stage": "Qualified" }], "total": 128 }
Frontend delivery
CSV API for Frontend
Move frontend teams from static JSON mocks to queryable APIs backed by CSV data.
CSV export -> frontend API
GET /v1/apis/frontend-data?limit=20
{ "data": [{ "id": "row-1", "name": "Sample" }], "total": 248 }
Catalog sync
CSV to REST API
When CSV exports become shared dependencies, publish a stable endpoint instead of chasing files.
CSV upload -> endpoint ready
GET /v1/apis/products?filter[status]=active&limit=20
{ "data": [{ "sku": "SKU-1042", "price": 79.99 }], "total": 248 }
