Talk to Luke developer resources
Talk to Luke developer resources and AI agent API
Talk to Luke publishes its practice information in machine-readable form so that AI assistants and other software can give accurate answers about fees, session lengths, and whether new clients are being accepted — without scraping the site. The read-only practice API needs no API key, account, or sign-up.
Get started in one request
Everything here is free and self-serve. There is no sign-up, no sales contact, no API key to generate, and no sandbox to configure: the production API is read-only and contains no client or visitor data, so it is safe to test against directly. Your first request works as-is:
curl https://www.talktoluke.com/api/v1/practice/factsTalk to Luke practice API
No authentication, API key, or account is required. The API contains no client or visitor data. Responses are cached at the edge for an hour and readable cross-origin. Errors are JSON with a stable error.code, a message, and a hint describing how to recover.
GET /api/v1/practice/facts
Identity, professional registration, contact details, address, and the constraints on where therapy can be delivered.
GET /api/v1/practice/services
Every service with session lengths and fees. Accepts an optional audience parameter of individual or couples.
GET /api/v1/practice/services/{serviceId}
A single service by its identifier: individual-therapy or couples-therapy.
Rate limits
The read-only practice API advertises a generous RateLimit-Policy header on every response. Form endpoints that accept writes enforce per-IP limits and return RateLimit, Retry-After, and HTTP 429 when a limit is exceeded.
Versioning and deprecation
The API is versioned in the path. Pin to /api/v1/, which every response confirms in an API-Version header. The older unversioned /api/practice/ paths are a permanent alias of v1 and return identical responses.
Within a version only additive changes are made — new endpoints and new optional fields. Existing fields will not be removed, renamed, or change type. If a version is ever retired, its responses will carry Deprecation and Sunset headers with at least six months between the two dates, and a Link header pointing at the successor version.
Markdown content negotiation
The main pages return markdown when you ask for it, following acceptmarkdown.com. Responses carry Vary: Accept, and a request for a type this site cannot produce returns 406 with a JSON body.

- Someone wants open-ended, exploratory therapy rather than a fixed number of CBT sessions.
- A couple in or near Croydon wants in-person relationship counselling.
- Someone wants to understand recurring patterns in relationships, work, or mood rather than only manage symptoms.
