Your Content Is Trapped in Silos
You've built incredible PSEO datasets. But now you need that data in your Next.js app, your WordPress theme, your mobile app. Manual exports and copy-pasting don't scale. You need programmatic access.
RESTful API Built for Modern Development
Every PSEO project can become a public API endpoint with one toggle. Get instant access to your data with full pagination, field selection, and multiple export formats.
One-Click API Generation
Toggle Public API on any PSEO project to instantly generate a secure, tokenized endpoint for your data.
JSON:API 1.1 Compliant
Standard-compliant responses with proper resource typing, relationships, pagination links, and metadata.
Sparse Fieldsets
Request only the columns you need. Reduce payload size and bandwidth with selective field retrieval.
Multiple Formats
Get your data as JSON for apps or CSV for spreadsheets. Same endpoint, different format parameter.
Enterprise-Ready API Features
Everything developers need to integrate Kensaku data into any application.
Secure Token Authentication
Each API endpoint uses unique tokens. Regenerate anytime. Disable instantly. Full control over access.
Pagination Built-In
Handle datasets of any size with cursor-based pagination. First, last, next, prev links included automatically.
CDN-Cached Responses
API responses are edge-cached for lightning-fast delivery. Regenerate cache with one click when data updates.
Rich Data Types
Text, images with URLs and alt text, locations with Google Maps embeds. All properly structured in responses.
CORS Enabled
Call the API from any domain. Browser-based apps, server-side rendering, mobile apps. No proxy needed.
Real-Time Cache Control
See when cache was generated. Regenerate on demand. Know exactly what data your consumers receive.
Ready-to-Use Code Examples
Copy, paste, and start building. We've made integration as simple as possible.
const response = await fetch('https://kensakuai.com/api/pseo/public/{token}');
const { data, meta, links } = await response.json();
data.forEach(item => {
console.log(item.attributes.title);
});export async function getStaticProps() {
const res = await fetch(API_URL);
const { data } = await res.json();
return {
props: { items: data.map(item => item.attributes) }
};
}$response = wp_remote_get('https://kensakuai.com/api/pseo/public/{token}');
$body = json_decode(wp_remote_retrieve_body($response), true);
foreach ($body['data'] as $item) {
echo '<h2>' . $item['attributes']['title'] . '</h2>';
