# Splice APIs

> Reference documentation for the Scan, Validator, SV, and Daml APIs that run on Canton Network nodes.

Splice nodes expose REST APIs that are separate from the [Ledger API](/sdks-tools/api-reference/ledger-api) and the [Admin API](/sdks-tools/api-reference/admin-api). These APIs are served by the Splice application layer running on top of Canton and provide access to Canton Network-specific functionality: querying network state, managing wallets, operating validators, and governing the network as a Super Validator (SV).

## Sub-pages

* [Splice APIs Overview](/sdks-tools/api-reference/splice-overview) — entry point and how the APIs fit together
* [Splice HTTP APIs](/sdks-tools/api-reference/splice-http-apis) — the HTTP/REST APIs at a glance
* [Splice Daml APIs](/sdks-tools/api-reference/splice-daml-apis) — Daml choice-based APIs exposed by the Splice DARs
* [Splice Daml Models](/sdks-tools/api-reference/splice-daml-models) — the Daml model packages shipped with Splice

### Scan APIs (read-only, public)

* [Scan Global Synchronizer Connectivity API](/sdks-tools/api-reference/splice-scan-gs-connectivity-api)
* [Scan Global Synchronizer Operations API](/sdks-tools/api-reference/splice-scan-gs-operations-api)
* [Scan Open API Reference](/sdks-tools/api-reference/splice-scan-openapi)

### Validator-side APIs

* [Validator APIs](/sdks-tools/api-reference/splice-validator-api) — wallet, user management, external signing, and validator administration

## Authentication

All Splice APIs except the public Scan API require a JWT token passed as an [OAuth2 Bearer token](https://datatracker.ietf.org/doc/html/rfc6750#section-2.1):

```
Authorization: Bearer <your-token>
```

The Scan API is publicly accessible and does not require authentication.
