X-Api-Key
string
header
required

API key (programmatic access — recommended)

Send your API key in the X-Api-Key header. Keys start with nxs_ and are created in the dashboard (or via POST /api/keys with a session JWT).

Each key is scoped to one chain and one network (for example cardano-mainnet), fixed at creation time. It cannot query a different network on the same chain, and it cannot query a different chain at all. A mismatched network parameter returns 400 Network Mismatch. Create one key per chain and network under the same account.

This is the credential most integrations should use.
