}Runs EasyCircuit's wiring checks on a complete circuit design without saving it. Returns status (passed or blocked), blockingIssues that prevent saving, designWarnings from general electrical rules (such as a part with no ground pin) that do not apply to every part, and reviewWarnings for pin facts that are not yet physically verified.
| Argument | Type | Description |
|---|---|---|
| design* | object | A complete circuit. nets: {net_id: {label, color '#rrggbb'}}. components: [{id, name, type: controller|sensor|switch|power|load|bus|protection|camera|assembly|wiring, pins: [{id, label, side: left|right, net}]}]. connections: [{id, from: 'componentId.pinId', to: 'componentId.pinId', net}]. Ids are short lowercase strings and pin labels are the part's real pin labels. The wiring checks expect every wired part's power and GND pins to be wired, a common GND, VCC, GND, SDA and SCL on I2C devices, and a battery or power-supply component for motors, pumps, solenoids and heaters. |

}Returns the electrical capabilities of an exact part: pin roles, drive type, voltage ranges, required terminals, protocols, and whether each fact is physically verified.
| Argument | Type | Description |
|---|---|---|
| limit | integer | |
| query* | string | Exact part name, catalog id, or part number. |

}Returns the pinout of an exact part: each pin's function, voltage, direction and polarity, with the source of each fact and any conflicting sources. Long pinouts are paged; next_offset is the offset of the next page.

}Saves a circuit design that has no blocking wiring issues and returns a link that opens it in the EasyCircuit editor, with schematic, breadboard and perfboard views, editing, and parts ordering. Anyone with the link can open a copy. Designs with blocking issues are not saved.
| Argument | Type | Description |
