# Developers & AI agents: Interstate Graphics

Interstate Graphics publishes a small, public, read-only interface so AI agents and developers can look up our products, capabilities, FAQ and quote requirements. No API key is needed.

## Quickstart

```bash
curl -s https://igiprint.com/wp-json/igi/v1/products?q=banner
```

## REST API (v1)

Base URL: `https://igiprint.com/wp-json/igi/v1` (alias `https://igiprint.com/api/v1`). Spec: [https://igiprint.com/openapi.json](https://igiprint.com/openapi.json)

| Method | Path | Description |
|---|---|---|
| GET | /company | Company facts, contact, certifications |
| GET | /capabilities | Production capabilities |
| GET | /products?q=&category=&page=&per_page= | Product catalog (paginated; `X-Total-Count`, `next_page`) |
| GET | /products/{slug} | One product |
| GET | /faq?q= | FAQ |
| GET | /quote-requirements | Fields needed for a quote, and where to submit |
| GET | /search?q= | Search products, pages, FAQ |

Errors are JSON:

```json
{"code":"not_found","message":"Unknown product slug.","data":{"status":404}}
```

Under `/api/v1/` errors use `{"error":{"code","message","status"}}`.
