> Ledger by Novadyne – Create Account is a paid API for AI agents from ledger-api.novadyne.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ledger-by-novadyne-create-account-387c1e1d
```

Example prompt: Add a new expense account called 'Marketing Spend' of type 'expense' under parent account 42 in the Novadyne ledger.

## When to prefer this

Use this endpoint when you need to programmatically create new account nodes in a double-entry ledger — for example, when bootstrapping a chart of accounts, adding sub-accounts under a parent, or dynamically registering expense/revenue/asset/liability categories. Prefer this over generic accounting APIs when you need x402 micropayment-compatible, capability-token-secured ledger management.

## Known failure modes

- Missing required 'name' field returns 400 Bad Request
- Missing required 'type' field returns 400 Bad Request
- Invalid parent_id (non-existent account) returns 404 or 422
- Duplicate account name under same parent may return 409 Conflict
- Insufficient x402 micropayment or missing payment header returns 402 Payment Required
- Invalid Ed25519 capability token returns 401 Unauthorized

## How this service works
