Type-correct payloads.

POST & PATCH bodies with required-field awareness and record-ID handling.

Batches with reference IDs.

Multi-sObject graphs with unique reference IDs in a single Composite API call.

Ask anything, explain everything.

Plans, history, saved queries and CSV exports - Dev Console power, zero context switching.

One round trip, whole graph.

Walk lookup trees with value precision. Live metadata, read-only, no mutations.

See the model, not just the fields.

Any org as an ERD - discover relationships, present with the laser, export hi-res PNG.

Any method, any endpoint.

Org-scoped or public REST calls with cURL paste, history and one-click collection staging.

Diff versions, node by node.

Edit payloads in a tree and compare versions side by side - virtualized for the biggest payloads.

Contracts, not guesswork.

Profiles, mappings, deterministic OpenAPI 3.1 - versions and compatibility included.

Export anywhere.

JSON, cURL with $SF_ACCESS_TOKEN placeholder, JS fetch, or Apex HttpRequest.
