Title: TETA+PI Author: tetapi Published: August 22, 2026 Last modified: August 22, 2026 --- Search plugins ![](https://ps.w.org/tetapi/assets/banner-772x250.png?rev=3660329) ![](https://ps.w.org/tetapi/assets/icon-256x256.png?rev=3660329) # TETA+PI By [tetapi](https://profiles.wordpress.org/tetapi/) [Download](https://downloads.wordpress.org/plugin/tetapi.1.1.0.zip) * [Details](https://wordpress.org/plugins/tetapi/#description) * [Reviews](https://wordpress.org/plugins/tetapi/#reviews) * [Installation](https://wordpress.org/plugins/tetapi/#installation) * [Development](https://wordpress.org/plugins/tetapi/#developers) [Support](https://wordpress.org/support/plugin/tetapi/) ## Description TETA+PI is trust infrastructure for digital entities — verified people, companies, APIs, AI models, MCP servers and agents, discoverable by AI agents. This plugin lets a site owner: * Connect the site to their TETA+PI entity with a personal API key. * Prove domain ownership (DNS TXT record or a well-known file, whichever is easier) directly from the WordPress admin. * Display a verified-entity badge anywhere via the `[tetapi_badge]` shortcode or the “TETA+PI Badge” widget. * Make the site agent-readable: once connected, the plugin adds a machine-readable JSON-LD block to every page’s ``, and serves /.well-known/agent.json, `/. well-known/agent-card.json` and `/llms.txt` from your own domain — so AI agents and crawlers (including ones that don’t execute JavaScript) can read your verified- entity data directly, not just see a visual badge. This release is 100% free — every feature above is fully functional with no payment required. Two premium modules are planned for later: **Module #1 ($25) — additional badge styles, automatic placement, multi-entity support, WooCommerce integration— and Module #2 ($52), a further tier coming after that. Neither is for sale yet; the settings page shows what’s planned and has a field to redeem a free code if TetaPi gives you one (e.g. as a thank-you for a social-media shoutout). Learn more at [tetapi.dev](https://tetapi.dev). ### External services This plugin connects to `api.tetapi.dev`, the TETA+PI API. It is operated by TetaPi GmbH, the same company that develops this plugin, and is required for the plugin’s core functionality: connecting your site to your TETA+PI entity, proving domain ownership, and displaying your trust badge. What is sent, and when: * When you save your Personal API Key under Settings > TETA+PI, that key is sent to `GET /businesses` to list the entities it can access. The key is stored encrypted at rest (using your site’s own WordPress salts), not in plain text. * When you click “Start verification” or “Check now”, your site’s domain (auto- detected from your site URL) and your chosen entity ID are sent to POST /businesses/{ id}/verify/domain/start and POST /businesses/{id}/verify/domain/check respectively, to prove you control the domain. * Whenever the `[tetapi_badge]` shortcode or the “TETA+PI Badge” widget is displayed on any page, your connected entity’s slug is sent to the public, unauthenticated` GET /businesses/by-slug/{slug}/public` endpoint to fetch your badge data. This response is cached for 15 minutes (WordPress transient) to limit requests. No visitor-identifying data is sent — every visitor triggers the same request for the same public entity data. * On every page load (for the JSON-LD block) and whenever /.well-known/agent.json,`/. well-known/agent-card.json` or `/llms.txt` is requested on your site, your connected entity’s ID is sent to the public, unauthenticated `GET /wk/{entity_id}/*` endpoints to fetch agent-readable data about your entity. Also cached for 15 minutes. No visitor-identifying data is sent. No data is sent to any other third party.

The plugin only talks to `api.tetapi.dev`, the TETA+PI API, using the API key you provide. No data is sent anywhere else. See “External services” below for exactly what is sent and when. ### Do I need a TETA+PI account? Yes — create a free entity at [app.tetapi.dev](https://app.tetapi.dev) first, then generate a personal API key from your account settings. ### Is my API key stored in plain text? No, it is encrypted at rest using your site’s own WordPress salts. ### Do I have to pay for anything? No. Every feature in this release is free. Two premium modules are planned for later (Module #1 / Module #2) but neither is for sale yet. ### How do I unlock Premium early? Premium isn’t for sale yet. TetaPi occasionally gives out free redeemable codes to early users, e.g. as a thank-you for a social-media shoutout. If you have one, enter it under Settings > TETA+PI > Premium to unlock it on your site. ### Does this plugin help with AI/agent discoverability, not just a visual badge? Yes. Once your entity is connected, the plugin adds a `schema.org` JSON-LD block to every page’s ``, and serves `/.well-known/agent.json`, /.well-known/agent- card.json and `/llms.txt` on your own domain — real structured data an AI agent can read directly, without needing to parse the visible badge text or execute any JavaScript. Before an entity is connected, none of this is served (no default/placeholder data — those URLs 404). ## Reviews There are no reviews for this plugin. ## Contributors & Developers “TETA+PI” is open source software.

A `schema.org` JSON-LD block is now added to every page’s `` once your entity is connected, and the plugin serves /.well-known/ agent.json, `/.well-known/agent-card.json` and `/llms.txt` on your own domain, proxied from TETA+PI’s agent-readable API and cached for 15 minutes. Nothing is served for a site that hasn’t connected an entity yet. #### 1.0.1 * Fix: domain ownership verification could fail even with a correct well-known file, because WordPress redirects the verification URL to add a trailing slash and the verifier does not follow redirects (by design, to prevent SSRF). The plugin no longer lets WordPress redirect that one URL. #### 1.0.0 * Initial release: settings/connect page, domain ownership verification, badge shortcode + widget, Premium module teasers + free promo-code redeem. ## Meta * Version **1.1.0** * Last updated **8 hours ago** * Active installations **Fewer than 10** * WordPress version ** 5.8 or higher ** * Tested up to **7.1** * PHP version ** 7.4 or higher ** * Tags * [ai agents](https://wordpress.org/plugins/tags/ai-agents/)[badge](https://wordpress.org/plugins/tags/badge/) [llms.txt](https://wordpress.org/plugins/tags/llms-txt/)[trust](https://wordpress.org/plugins/tags/trust/) [verification](https://wordpress.org/plugins/tags/verification/) * [Advanced View](https://wordpress.org/plugins/tetapi/advanced/) ## Ratings No reviews have been submitted yet.
