Source OpenAPI: 0xArchive API 1.8.0; 227 paths; 217 component schemas.
Add a wallet so address scoped event types can report on it. Adding a wallet that is already watched changes nothing and does not count against the cap again. Hyperliquid bridge system addresses are refused, because such an address is a counterparty to every bridge movement of its token rather than an account. A plan without webhook delivery, or one already at its watched wallet cap, is refused with the reason and the way forward. Authenticate with an API key or a signed-in dashboard session. Costs no credits.
