model to list models via ir.model, or specify one to inspect its fields:
limit (1–200, default 50) and offset, and return has_more / next_offset. domain filters model discovery only. fields narrows field discovery only. All calls accept instance and the read context documented in Odoo Query.
If model discovery is denied, try a known model such as res.partner, sale.order, product.product, stock.quant, or account.move. Access to ir.model is distinct from access to business records.
