WP Webhooks AI
The hosted model service behind Build with AI — a free 55-credit trial on every install, then a monthly pool of credits with every Pro license. No provider signup, no API keys to paste.
WP Webhooks AI is the hosted model service behind Build with AI: our servers, our provider keys, nothing for you to sign up for. The free plugin gets a one-time 55-credit trial on it, and every Pro license adds a monthly pool of AI credits that renews automatically. It appears as "WP Webhooks AI (included)" under the Build with AI model source whenever the Pro plugin is active, and the bring-your-own-key option never goes away.
Free trial on every install
Since 2.8.0 the free plugin runs on the same hosted service without a license. Your first prompt to Build with AI claims a one-time grant of 55 credits — about five agent turns, or two complete automations — with no key, no account and no card. The balance shows in the model bar and on the Free trial card in Settings → AI Builder. It is one trial per site and it is never refilled: when it runs out, connect your own provider key or activate Pro to keep building. The trial is also the last source Auto resolves to, so a site that already has connectors or its own key never spends it.
Included with every Pro plan
Each tier renews a monthly credit pool — Starter 5,000, Business 12,500, Agency 30,000. Credits are charged by usage: a typical agent turn costs about 11 credits, and a full automation — planning it, reading your hooks and REST routes, creating the webhook, mapping fields, and test-firing it — usually lands around 25. That puts even the smallest plan at 200+ builds a month, Business at 500+ and Agency at 1,200+. Credits reset at the start of each billing period.
More than a model
Running on the hosted service also opens the Payload Library — reference payloads for triggers your site has never fired, so the agent can map fields without sending you off to produce the event by hand first. The lookup itself costs no credits. It also opens the API Docs Library — the current reference for HubSpot, Airtable, Slack, Notion, Stripe and dozens more, read into any turn that targets one, and researched from the vendor's docs on the spot when nobody has asked for that service before; about one credit on the turn that uses it. A site building on its own provider key is paying its own bills and keeps the previous behaviour.
Automatic on activation
Activating a Pro license switches Build with AI to the hosted service automatically — but it never overrides an explicit choice: if you have deliberately selected your own API key or the WordPress AI connectors, that selection stays. The hosted status travels on every settings response, so switching between Auto, connectors, your own keys, and WP Webhooks AI never loses the option.
Live balance as you build
The model bar in Build with AI shows how many credits are left and counts down after every agent call. The current balance and the monthly reset date are also shown in provider settings, so there is never a surprise about what remains.
When credits run out
Out-of-credits, rate-limit, and provider errors surface directly in the builder chat rather than failing silently — and you can switch back to your own provider key at any time to keep working. A spent free trial is treated as a choice rather than an error: the builder says so, points you at a free Gemini key or Pro credits, and everything you have already built stays on the site untouched. The routes forward survive a page reload, and they disappear the moment another model is connected.
