# Read the bounded public dependency change feed.

`GET /api/dependency-changes`

## Request

- Base URL: `https://huggingbay.xyz`
- URL: `https://huggingbay.xyz/api/dependency-changes`
- Auth: none declared

Returns one cursor-bound page of material changes affecting public locks, Run Cards, recipes, representations, and portable packs. The page and event digests make gaps or reordering detectable; polling this endpoint is not a webhook subscription.

**Inputs.** Path, query and header fields are listed below. No request body is required.

**Outputs.** See each status below for its media type, schema and headers. A missing record or unavailable capability is not a successful empty result.

**Errors.** API JSON failures use the documented response schema. Read code, message and next; retry only when the response allows it. Auth, invalid input and missing records need a caller change.

**Rate limits.** Public read budgets apply by client IP and route group. This operation can have a smaller route-specific budget. Read Retry-After on 429 or retryable 503 responses.
