pre.dev/projects/key — one-click API key copy

New page at https://pre.dev/projects/key. Sign in once and copy your key — masked-key reveal + copy button inside the dashboard sidebar. Useful when sharing example apps and SDK quickstarts: link any “Get an API key” CTA straight here. Unauthenticated visitors are bounced to sign-in and auto-returned to /projects/key after.

Browser Agents — typed billing errors with actionUrl

Non-2xx responses for POST /browser-agent now carry a structured body: 
{
  "error": "Need ~0.5 credits, have 0.00. Buy more to continue.",
  "code": "INSUFFICIENT_CREDITS",
  "actionUrl": "https://pre.dev/projects/browser-agents?upgrade=credits"
}
code is one of SUBSCRIPTION_REQUIRED, INSUFFICIENT_CREDITS, RATE_LIMITED, QUEUE_FULL, BATCH_TOO_LARGE. actionUrl (when present) deep-links the user back to pre.dev with the right billing modal pre-opened — window.open(actionUrl) is enough to send the user to the credit-purchase or subscription flow without any extra UI. The same body is emitted on the SSE error event when streaming.

​
Node SDK — predev-api@1.1.0

import { InsufficientCreditsError, SubscriptionRequiredError } from 'predev-api';

try {
  await client.browserAgent(tasks);
} catch (e) {
  if (e instanceof InsufficientCreditsError) window.open(e.actionUrl);
  else if (e instanceof SubscriptionRequiredError) window.open(e.actionUrl);
}
New typed exceptions: SubscriptionRequiredError, InsufficientCreditsError, QueueFullError, BatchTooLargeError. All non-breaking — existing instanceof PredevAPIError checks still match. See the Node SDK error-handling docs.

​
Python SDK — predev-api==1.1.0

from predev_api import InsufficientCreditsError, SubscriptionRequiredError
import webbrowser

try:
    client.browser_agent(tasks)
except InsufficientCreditsError as e:
    if e.action_url: webbrowser.open(e.action_url)
except SubscriptionRequiredError as e:
    if e.action_url: webbrowser.open(e.action_url)
New exceptions mirror the Node SDK with action_url field. See the Python SDK error-handling docs.
