Action402 Mockups

Landing directions

Five ways to make Action402 feel precise, agent-native, and verifiable.

Each mockup keeps the same brand core: paid execution for autonomous agents, x402 discovery, exact payment, and signed receipts.

Action402
01 Relay Console

x402 paid execution layer

Pay. Execute. Prove.

Reliable webhook and API execution for autonomous AI agents using x402 payments on Base.

View API Bazaar Metadata
01

Built for agents

No accounts required in the buyer path.

02

Paid per action

Charge exact x402 micro-payments.

03

Receipts by default

Return signed proof for every execution.

Action402
02 Receipt Ledger

signed receipts for paid actions

Every action returns proof.

Action402 executes bounded webhook calls and records the hashes, status, and signature an agent can verify later.

03 Bazaar Route

built for x402 discovery

The paid action route agents can discover.

Publish one clear x402 endpoint for webhook execution, Bazaar metadata, and public receipt verification.

Open metadata View route

Paid webhooks

Let agents trigger bounded side effects without broad API keys.

Usage-gated tools

Charge per webhook, not per seat.

Verifiable execution

Expose public receipts for agent audit trails.

04 Agent Flow

from payment to proof

Agents pay once. Action402 executes exactly once.

A narrow relay for paid webhook and API actions with retries, idempotency, and signed receipts.
