Schema → action → browser

Pick a real app. See the typed schema, the API call your agent makes, and the browser running it.

Your remote browser — Webmapper drives the real site.

Built for agents that do real work

Not toy demos. The same sites your users already log into — with typed actions instead of brittle scripts.

E-commerce

Amazon

Search by department, open ASINs, cart writes behind a confirm gate.

Travel

United · Expedia · Airbnb

Flight search with fare cards, check-in flows, booking slices.

GTM

People and company search, profiles, messaging on logged-in sessions.

DevOps

Slack Admin

Create apps from manifest, install, extract OAuth tokens — one action chain.

How it works

Discover the schema

GET /v1/apps/amazon — actions, param types, what’s reversible vs gated.

POST one action

Name, params, optional browser attach. No selector soup — just JSON in and out.

Get proof

Structured view + evidence level. Retry, audit, or chain the next action.

API-priced, not browser-priced

Pay per validated action. Attach your own remote browser over CDP — we don’t mark up browser hours.

Your browser, typed semantics

Runs in the session you control. Webmapper handles preconditions, validation, and structured extraction.

70+ app specs in Lean

Amazon, Gmail, Jira, Datadog, banks, marketplaces — authored as dependent types, not prompt hacks.
