# Vault configuration history

`GET /v3/evk/vaults/{chainId}/{address}/config-history`

## Request

- Base URL: `https://v3.euler.finance`
- URL: `https://v3.euler.finance/v3/evk/vaults/{chainId}/{address}/config-history`
- Auth: none required

LTV (`ltv`), cap (`cap`) and interest rate model (`irm`) changes of this vault in one
timeline, newest first; `meta.total` counts all three kinds. There is no type filter:
use cap-history, ltv-history or irm-history for one kind. Without `from` and `to` the
timeline is unbounded.

## Path parameters

- `chainId` integer, required
- `address` string, required

## Query parameters

- `from` integer
- `to` integer
- `offset` integer
- `limit` integer

## Response `200`

Vault config history

- object
  - `data` ConfigHistoryItem[]
    - `type` 'ltv' | 'cap' | 'irm': Kind of change.
    - `data` object: The values set by the change, by `type`. `ltv`: `collateral` (checksummed address), `borrowLTV`, `liquidationLTV` and `initialLiquidationLTV` as basis-point strings, their legacy fraction aliases `borrowLtv`, `liquidationLtv` and `initialLiquidationLtv`, `targetTimestamp` (ISO date-time, null when no ramp is set) and `rampDuration` (seconds). `cap`: `supplyCap` and `borrowCap` as the raw EVK uint16 encodings in JSON integers, not resolved amounts; encoded zero means unlimited. `irm`: `interestRateModel` (checksummed address).
    - `blockNumber` string: Block number of the change
    - `timestamp` string, date-time: Timestamp of the change
    - `txHash` string: Transaction hash
    - `logIndex` integer: Log index within the transaction receipt.
  - `meta` PaginationMeta
    - `total` integer: Exact total count when the endpoint provides one.
    - `hasMore` boolean: Indicates whether another page exists beyond the current page.
    - `offset` integer
    - `limit` integer: Echoed page size after endpoint-side clamping.
    - `outcome` 'disabled' | 'removed': On a toolbox config DELETE, what happened to the row.
    - `products` ProductLabels[]: On a curation vault `POST`, `PUT`, or `PATCH`: the products the write touched (the one the vault left and the one it joined) as they are after the write, `governanceMode` included, so the caller applies them instead of re-reading.
      - `id` string, required
      - `chainId` integer, required
      - `entityId` string, required
      - `coBrandEntityIds` string[], required: Additional entities whose logos should be displayed. Product management remains exclusively with entityId.
      - `name` string, required
      - `logo` string, nullable
      - `description` string, nullable
      - `url` string, nullable: Absolute https URL.
      - `portfolioNotice` string, nullable
      - `isDeprecated` boolean, required
      - `deprecationReason` string, nullable
      - `notExplorable` boolean, nullable, required: Curator listing flag, outranked by platform overrides and by Euler's deprecation on the assessment. `null` leaves the decision to deprecation, `true` hides the vault(s) from discovery, `false` keeps listed a vault the curator deprecated, but never one Euler deprecated.
      - `governanceMode` 'governed' | 'ungoverned' | 'unknown', required: Derived by the server from the on-chain governor of member vaults; clients cannot set it. Products are created as `unknown`. Every vault assignment recomputes the mode over the resulting member set and rejects sets that mix governed and ungoverned vaults. Layer 2 adopts `governed` or `ungoverned` for an `unknown` product once its membership verifies against chain state. Entity members cannot update or delete an `ungoverned` product or its vaults after the initial assignment.
      - `resolved` ResolvedProductLabels, required: Read-time entity fallbacks for display. Derived, never stored.
        - `entityName` string, nullable, required
        - `url` string, nullable, required: Product url, falling back to the owning entity url.
        - `logo` string, nullable, required: Product logo, falling back to the owning entity logo.
      - `anyExplorableLend` boolean, required: True when at least one member vault is lend-discoverable per the materialized visibility verdicts. Live chain state (e.g. borrowability) is deliberately excluded.
      - `anyExplorableBorrow` boolean, required: True when at least one member vault is borrow-discoverable per the materialized visibility verdicts. Live chain state (e.g. borrowability) is deliberately excluded.
      - `createdAt` string, date-time, required
      - `updatedAt` string, date-time, required
      - `hold` LabelHoldSummary: What a draft read shows on a held row.
        - `id` string, uuid, required
        - `kind` 'quarantine' | 'entity-hold', required
        - `reason` string, required
        - `since` string, date-time, required
      - `platformListing` ProductPlatformListing: The platform-owned discovery decision on a product, as a product row shows it.
        - `notExplorableLend` boolean, required
        - `notExplorableBorrow` boolean, required
        - `reason` string, nullable, required
    - `timestamp` string, date-time, required
    - `chainId` string: Comma-separated chain IDs for multi-chain responses.
    - `degradedProviders` string[]: Live providers whose data is incomplete in this response.
    - `excludedChains` object[]: On a read across chains that names no `chainId`: the served chains it left out because they do not run the capability the operation needs, rather than reading them as empty. Absent when no chain was left out.
      - `chainId` integer, required
      - `capability` 'indexing' | 'activity' | 'prices' | 'historicalPrices' | 'assessments' | 'labels' | 'logos' | 'stats' | 'risk' | 'rewards' | 'apys', required
