Desk facet: money → credit desk → strategies

One entry per (credit desk, denomination): the tokens that put you on that desk, what DEPOSITING them pays, and what LOOPING them pays. Built from the same data as `/v1/data/earn` (its cached catalogue, with its default exclusions — `deposit.count` is what a bare listing request shows) and `/v1/data/lending/pairs/optimize` (at its defaults). Cached 5 min, served stale while refreshing.

A token's **credit desk** (see `CreditDesk`) is the token's own `issuer`, unless that issuer is a pure instrument wrapper (Pendle, Spectra, Exponent, or any token carrying a `pendle`/`spectra`/`exponent`/`receipt` prop) — then its fewest-hop non-instrument `issuerExposures` entry, with the instrument issuer as `via`. A PT-sUSDe is `{ id: 'ethena', via: 'pendle', hops: 1 }` — Pendle's instrument, Ethena's credit; Strata's srUSDe is `{ id: 'strata', hops: 0 }` — its own issuer's token, even though it is exposed to Ethena. An instrument issuer is never a desk.

Deposit rows are bucketed by their deposit token's desk; loop rows by their COLLATERAL's desk. A loop counts in a money only when its collateral AND its debt are that money (`wstETH`/`WETH` is an ether loop, `sUSDe`/`USDC` a dollar loop); a cross-money loop (`sUSDe`/`WETH`) is a price bet and appears in no entry.

**Two things are deliberately NOT a desk:**
- **A loop's debt.** A stablecoin you owe is not an exposure to its issuer: a USDC-funded sUSDe loop is Ethena credit, not Circle credit. Strategies group by their COLLATERAL's desk.
- **A vault's `exposure` block.** That is the curator's current allocation (one Fluid USDC vault spans eight collaterals and six desks), a DISCLOSURE about the position that moves on every rebalance. A vault row's desk is its deposit token's (`asset.desk`): a Steakhouse USDC vault is on Circle's desk.

Tokens with no desk are reported rather than dropped: plain ETH / WETH (nobody's liability) under `{ id: 'plain:ETH', name: 'Ether', kind: 'plain' }`; every other one under `{ id: 'sym:<SYMBOL>', name: <symbol>, kind: 'unattributed' }` — a curation gap, not an issuer (there is no plain BTC: every BTC token is someone's IOU).

```jsonc
[{ "desk": { "id": "ethena", "name": "Ethena", "kind": "protocol" },
   "denomination": "USD",
   "members": [{ "assetGroup": "USDE", "symbol": "USDe", "role": "base" },
               { "assetGroup": "SUSDE", "symbol": "sUSDe", "role": "savings" },
               { "assetGroup": "Ethereum::PT-sUSDE-…", "symbol": "PT-sUSDE-…", "role": "pt", "via": "pendle" }],
   "deposit": { "count": 19, "maxApr": 11.2, "tvlUsd": 4.1e9 },
   "loop":    { "count": 55, "maxNetApr": 33.1, "maxLeverage": 17.6 } }]
```

- `members[].role`: `base` (the desk's own money), `savings` (its yield-bearing wrapper), `pt` (a principal token over it), `wrapper` (any other wrapper). `via` names the instrument issuer when it is not the desk.
- `deposit.maxApr` and `loop.maxNetApr` are PERCENT (the units of `rate.total` and `aprTotal`); `null` when the count is 0. `loop.maxNetApr` is the best `aprTotal` (net, at max leverage, incl. rewards).
- `partial: true` on `deposit` / `loop` when a source was unavailable or a walk hit its cap — the figures are then a lower bound.
- Sorted by `deposit.tvlUsd`, then `loop.count`.

**Parameters**

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `chainIds` | query | string | yes | CSV of chain ids (alias `chainId`). See the `ChainId` schema for the full set of supported chains. |
| `denomination` | query | string | no | Money to keep, uppercase-insensitive: `USD`, `EUR`, `ETH`, `BTC`, … (`ETH` groups LSTs/LRTs by their desk — Lido, ether.fi, Rocket Pool, Coinbase, …; `BTC` likewise — BitGo, Coinbase, Lombard, …). Omit for every denomination (deposit tokens with none are then reported with `denomination: null`). |

**Response `200`** — Array of `{ desk: {id,name,kind?}, denomination, members: [{assetGroup,symbol,role,via?}], deposit: {count,maxApr,tvlUsd,partial?}, loop: {count,maxNetApr,maxLeverage,partial?} }`.

| Field | Type | Description |
| --- | --- | --- |
| `success` | true |  |
| `data` | object | Informational payload. `null` when the endpoint only builds calldata. |
| `actions` | null |  |

**Example response**

```json
{
  "success": true,
  "data": {}
}
```

**Response `400`** — Validation error

**Response `429`** — Rate limited. Unauthenticated callers share a per-IP budget; send an `x-api-key` header to lift it. Retry with exponential backoff.

**Response `500`** — Unexpected server error. Safe to retry with backoff.

**Response `502`** — An upstream data source or protocol origin failed (`error.code` is `ORIGIN_FAILED`). `error.details` carries the per-origin status. This is also what a missing or malformed required parameter currently returns, rather than a 400.
