darwin.cloud — agent-first commerce

Real purchases. Bounded. Signed.

Darwin is the agent-first commerce layer. Our agent completes authorized purchases on your WebMCP surface, only where it provably succeeds, and returns a cryptographically signed receipt for every order.

$ pip install darwin-agentic-cloud
for merchants

Converted demand. Every order proven.

Darwin routes real buyer-intent transactions to your checkout and proves each one. Not a blog link, not a cookie hoping to fire. An agent that places bounded, authorized orders on your WebMCP surface, then hands back a signed receipt. You get the sale and the proof in the same step.

✓
Converted, not curious. The agent only acts on a request to buy. Every routed order is buyer intent, already decided.
✓
Bounded, not reckless. Every purchase rides an AP2 mandate, a signed spend cap and approved-merchant list. No unbounded spend, no fraud surface. The card stays tokenized in the user's Google account. Darwin never holds it.
✓
Integration-attributed, not guessed. Orders are credited to the integration that placed them, not a last-click cookie. Clean attribution, clean payout.
✓
Compliant surfaces only. If your surface is not WebMCP-ready, the agent does not go there. It only routes where it provably completes.
the transaction receipt

A signed receipt for every purchase.

Every order Darwin places returns a v0.2 attestation under the webmcp-action evidence schema. Merchant, item, amount, order id, and the AP2 mandate that authorized it, all signed and verifiable against the public keylist. This is the expense record, the audit trail, and the payout proof in one artifact.

how it works

Route. Gate. Authorize. Pay. Sign.

Five steps, one chain, cryptographic end to end. The user's Google account is the only thing they connect.

1
Route. The agent maps the request to the right WebMCP merchant.
2
Gate. It probes the surface. WebMCP-ready, it proceeds. Not ready, it refuses. No fallback, no scraping.
3
Authorize. It checks the AP2 mandate, the user's signed spend cap and approved merchants.
4
Pay. The tokenized credential charges at WebMCP checkout. The agent never holds the card. Darwin never sees it.
5
Sign. Darwin returns a signed receipt anyone can verify, offline, against the public keylist.
