Address	`https://api.hanzo.ai/v1/books/vendors`
Method	`GET`
Operation	`get_books_vendors`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Returns the org's vendor book: each canonical vendor, the alias spellings a receipt may print it under, and the expense account new bills from it default to. A vendor here is what makes a scanned bill self-classify instead of asking again.

Request

1 field.

Field	In	Type	Required	Description
`sandbox`	query	string	—	Sandbox reads the org's SANDBOX ledger when it is exactly "true"; anything else reads the live one.

Response

Status	Body	Meaning
`200`	books.vendorsOut	ok
`default`	problem-details	refused

200 body — 4 fields.

Field	In	Type	Always	Description
`vendors`	body	books.VendorRow[]	—	Vendors is every vendor the org has recorded, canonical name ascending.
`vendors[].aliases`	body	string[]	—	Aliases are the other spellings a receipt may print the vendor under; a scan matching any of them resolves to this vendor.
`vendors[].canonical`	body	string	—	Canonical is the vendor's one true name, and the key an upsert writes by.
`vendors[].defaultCategory`	body	string	—	DefaultCategory is the COA expense account new bills from this vendor book to.

Failure carries the platform error shape — see Errors.

MCP reaches books through the books tool, which names its 20 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:
