@@ -70,6 +70,9 @@ Provider settings reuse normal provider config fields:
| `providers.<name>.apiBase` | Optional custom base URL |
| `providers.<name>.extraHeaders` | Headers merged into provider requests |
| `providers.<name>.extraBody` | Extra JSON fields merged into provider request bodies |
| `providers.<name>.proxy` | Explicit trusted HTTP proxy for provider requests and returned image URL downloads |
For providers that return image URLs, direct downloads use DNS pinning. When an explicit provider `proxy` is configured, nanobot validates the initial URL and every redirect locally, then relies on that trusted proxy for final DNS resolution and network egress. Process-wide proxy environment variables are not used for these downloads.
Both camelCase and snake_case config keys are accepted, but docs use camelCase to match `config.json`.
