ZeroClick
ZeroClick
Storefront and payment layer that turns any API or product into a service AI agents can discover, pay for with x402 or MPP, and use.
Key features
- Machine-Readable Storefront: Every seller gets a hosted pay URL that agents read directly to discover available services, plans, and prices without a human-facing web page.
- x402 and MPP Payment Rails: Agents pay through the x402 and MPP protocols, with settlement to the seller's connected Stripe account in either fiat or USDC.
- On-the-Spot Wallet Creation: If a buying agent arrives without a wallet, ZeroClick provisions one during the transaction instead of failing the purchase.
- Agent Identity and Verification: Every agent is given an identifier and verified before a call is signed and forwarded, and every call is logged for tracking and abuse prevention.
- Billing Guard SDKs: Seller SDKs for TypeScript, Python, Go, and Ruby implement the verify-check-allowance-serve-settle contract, with a REST walkthrough for custom integrations.
- Flexible Plan and Meter Model: Services are billed through meters and plans supporting pay-as-you-go, credits, subscription, or subscription-plus-usage, with a pre-request allowance check.
- Agent Index Registration: ZeroClick publishes seller services to the major agent indexes so buying agents can discover them without a direct integration.
- Transaction Analytics Dashboard: Transaction-level reporting on agent traffic, origin platforms and models, payment-method split across x402, MPP, USDC and fiat, and per-service conversion rates.
Best for
- API Monetization for Agents: Putting an existing data, enrichment, or generation API behind a pay URL so autonomous agents can buy calls without a human signup flow.
- Agentic Commerce Readiness: Making an existing product purchasable by shopping assistants as agent-driven traffic replaces human browsing.
- Usage-Based Metering: Charging agents per request or per output token through meters and allowances rather than fixed seats.
- Agent Traffic Analytics: Understanding which agent platforms and models are driving purchases, and which services convert best with them.
- Crypto and Fiat Settlement: Accepting USDC from wallet-native agents while still settling into a conventional Stripe account.
- Enterprise Agent Sales Governance: Running agent-facing sales with roles, permissions, pricing controls, SSO/SAML, and a per-call audit log across a team.
