Direct answer

Daydreams Agent Payments is the payment capability across Daydreams software: it helps an agent interpret machine-readable terms, apply spending policy, authorize a supported payment, and send proof with a service request. It uses published protocols and settlement assets; it is not a claim that payment alone makes an autonomous purchase safe or correct.

Who it is for

Developers and product teams building agents that must buy API calls, tools, content, or task outcomes under explicit budgets and audit requirements.

How it works

Read the price and method

The client parses the service's current terms rather than relying on a hard-coded marketing price.

Enforce authority

The application checks asset, amount, recipient, network, and budget before allowing a wallet or account to sign.

Pay and retain evidence

The client supplies protocol-specific proof and retains the commercial and application records needed to reconcile the result.

Published evidence

x402 documents an HTTP-native challenge, signature, verification, and settlement flow.
MPP publishes a separate open machine-payment protocol.
Circle documents USDC and its supported chains and contracts.

Limitations

Supported protocols and assets depend on the specific Daydreams component and release.
Payments need secure key management, compliance controls, and accounting.
Settlement does not prove service quality or create a universal refund mechanism.
