 ### Endpoints
 
-`endpoint(route, handler)` takes `{ method, path, mode }`, where `mode` is `"read"` or `"write"`. Both `method` and `path` must be literal strings, because the compiler reads them from source without running it. The handler gets `(ctx, req)`, where `req` carries `method`, `path`, `url`, `headers`, `query`, and `text()` / `json()` / `bytes()`.
+`endpoint(route, handler)` takes `{ method, path, readOnly? }`. `GET` and `HEAD` are read endpoints by default; every other method is a write endpoint. Set `readOnly: true` for a read-only `POST`, or `readOnly: false` for a `GET` that writes. Both `method` and `path` must be literal strings, because the compiler reads them from source without running it.
