Choose the Right API - Anyway

Anyway exposes separate supported integration surfaces for merchant servers, webhook receivers, agent runtimes, and instrumented applications.

Surface	Audience	Authentication	Primary capability
Merchant API	Merchant backend	`X-API-Key`	Commerce records
Webhook delivery	Merchant HTTPS endpoint	Ed25519 signature	Receive order lifecycle events
Agent Wallet API	Agent runtime	P-256 request signature	Read policy/history and authorize wallet actions
SuperAPI directory	Agents and developers	Public discovery; Agent Wallet for paid calls	Discover and call x402 services
Telemetry collector	Instrumented applications	Agent Traces API key	Export OpenTelemetry traces

Public integration rules

The Merchant API is the supported server-to-server commerce API. Agent Wallet, webhook, SuperAPI, and telemetry contracts are also documented because customer code calls or receives them directly.

Do not send a Merchant API key as a Bearer token and do not treat an Agent Wallet Key as a merchant credential.

Base URLs

Merchant API:       https://merchant-api-prod.anyway.sh
Agent Wallet API:   https://api.anyway.sh
SuperAPI directory: https://marketplace-prod.anyway.sh

Use URLs returned by Anyway, including paymentLinkUrl and callable SuperAPI URLs. Do not derive alternate links or assume that all surfaces share one hostname.
