Grabbit Managed Screenshot Service Build (7-10 days)

A productized retainer that wires Grabbit's POST /grabs endpoint, CLI, and MCP server into a client's existing sites so screenshots land in their storage or inbox on a schedule, without the agency running headless Chrome. Built for agencies serving 5+ AI-native or compliance-driven clients.

Prerequisites
  • Grabbit API key provisioned through the dashboard or `npx grabbit.live login`, with a test POST /grabs returning a hosted image URL
  • Client sign-off on the target URL list (cap the first engagement at 10 URLs) and the destination for delivered images
  • A storage or inbox endpoint the client already owns, since Grabbit returns CDN-hosted URLs rather than pushing files into arbitrary systems
  • Written usage estimate from the client, because the per-grab rate of $0.002 USD makes volume the single biggest driver of both their bill and your margin
  • One engineer who can read webhook signatures and debug selector-targeted captures against real client pages
Execution Timeline
  • 1.Provision the API key and run a first POST /grabs against a client URL to confirm pixel-perfect output
  • 2.Verify cookie-banner dismissal and full-page capture on two of the client's messiest pages
  • 3.Record baseline grab counts per URL so the usage estimate is grounded in real traffic
  • 1.Map every target URL to its capture parameters: full_page, width, format, selector, and wait time
  • 2.Test selector-targeted crops on pages where the client only wants a pricing table or hero section
  • 3.Log edge cases (lazy-loaded images, login walls) that need a wait time or a different selector
  • 1.Configure async grabs plus signed webhooks so captures fire without blocking the client's own jobs
  • 2.Validate webhook signature verification in the client's receiving endpoint
  • 3.Confirm idempotent and SSRF-guarded behavior by replaying a duplicate request and checking for a single stored image
  • 1.Wire the CLI into the client's CI or scheduled job so captures run on their cadence, not yours
  • 2.Point delivery at branded cdn.grabbit.live URLs so screenshots carry the client's identity
  • 3.Set a retry path for failed grabs and a log the client can read without calling you
  • 1.Connect the MCP server to whichever agent runtime the client uses (Claude Code, Codex, OpenClaw, or Cursor)
  • 2.Run an end-to-end agent test where the agent captures a page and reasons about what it sees
  • 3.Document the agent prompt pattern that triggers a grab and where the returned URL gets consumed
  • 1.Draft the runbook: how to add a URL, change a selector, and rotate the API key
  • 2.Build a monthly usage report template that shows grabs consumed against the client's allowance
  • 3.Set the alert threshold that tells you a client is approaching their plan ceiling before they notice
  • 1.Hand off credentials and the runbook in a recorded walkthrough
  • 2.Agree the retainer scope: how many URLs, what cadence, and who owns new URL requests
  • 3.Confirm the top-up path with the client so overage is a conversation, not a surprise invoice
  • 1.Run a 24-hour soak test across all target URLs and reconcile actual grab volume against the estimate
  • 2.Fix any selector drift found during the soak and re-verify webhook delivery
  • 3.Close the engagement with a written volume forecast the client can budget against
$1,800 setup fee for the first client, matching the Grabbit Starter Screenshot Setup pattern at 16 hours of build time. Ongoing tool cost runs at $0.002 USD per grab, so a client capturing 25,000 pages a year sits inside the Annual tier's 25,000 live grabs, while heavier accounts top up 50,000 for $100 or 125,000 for $250 on Scale.7-10 days
ROI Logic

The setup fee is billed once at $1,800 against roughly 16 hours of delivery work, and the recurring margin comes from the retainer you attach to monitoring, URL changes, and usage reporting. Tool cost stays predictable because grabs are metered at $0.002 USD each and top-ups are published (50,000 for $100, 125,000 for $250), so a client burning 100,000 grabs a year costs you a few hundred dollars against a retainer priced in the thousands. Margin collapses only when you accept a client whose volume you never estimated, which is why the day-one baseline grab count matters more than any other step.

Deliverables
  • Configured Grabbit capture workflow covering up to 10 client URLs with full_page, width, format, selector, and wait-time parameters documented per URL
  • Signed webhook receiver wired to the client's storage or inbox, with signature verification tested against a replayed request
  • Agent integration notes showing the MCP server connected to the client's runtime (Claude Code, Codex, OpenClaw, or Cursor) with a working capture prompt
  • Monthly usage report template tracking grabs consumed against the client's plan allowance and top-up thresholds
  • Client runbook covering API key rotation, adding URLs, selector changes, and the escalation path for failed captures
Definition of Done

The client's scheduled job captures every agreed URL through Grabbit, delivers signed webhook payloads to their storage, and their agent runtime can trigger a grab and read the returned cdn.grabbit.live URL without anyone on your team touching the pipeline.
