Inline comments:
In `@packages/uniswapapi/client.ts`:
- Around line 54-75: Update packages/uniswapapi/client.ts lines 54-75 in the
ApiError translation to preserve status and retryAfter on UniswapApiAPIError.
Update packages/uniswapapi/error-handlers.ts lines 5-30 to match translated
errors via code, and add a handler before DEFAULT for retryable 500/503
responses using exponential backoff. In packages/corsair/core/endpoints/bind.ts
lines 206-245, return the recursive call(...) result so successful retries
propagate.
In `@packages/uniswapapi/endpoints/order.ts`:
- Around line 10-16: Update the request path in the order status handler using
makeUniswapApiRequest to /v1/orders, and update the corresponding test assertion
to expect the same endpoint.
In `@packages/uniswapapi/endpoints/quote.ts`:
- Around line 19-21: Update the quote handler around the slippage fields to
enforce exactly one valid mode: require and forward slippageTolerance, or add
autoSlippage and validate that exactly one of slippageTolerance and autoSlippage
is defined, rejecting requests where both are missing or both are provided.
In `@packages/uniswapapi/endpoints/types.ts`:
- Around line 80-93: Update CreateSwapInputSchema in
packages/uniswapapi/endpoints/types.ts (lines 80-93) to include permitData and
validate that permitData and signature are supplied together when applicable.
Update the swap handling in packages/uniswapapi/endpoints/swap.ts (lines 11-20)
to forward the unchanged permitData alongside the signature. Extend the test in
packages/uniswapapi/endpoints/endpoints.test.ts (lines 116-145) to expect both
fields.
- Around line 16-23: Update the approval schema near the approval field and the
permitData schema in packages/uniswapapi/endpoints/types.ts at lines 16-23 and
69-72 to accept null as well as omitted values by making both optional schemas
nullable. Preserve their existing object validation and passthrough behavior.
- Around line 130-144: Align the Uniswap API endpoint implementations and
schemas with the current OAS: in packages/uniswapapi/endpoints/types.ts, update
the swaps, orders, and swap_7702 request/response contracts; in
packages/uniswapapi/endpoints/swap.ts, require txHashes or userOpHashes and
return requestId with swaps; in packages/uniswapapi/endpoints/transaction.ts,
use the CreateSwap7702Request contract and return requestId, swap, and optional
gasFee; update the affected cases in
packages/uniswapapi/endpoints/endpoints.test.ts to assert the revised paths,
parameters, bodies, and response shapes.

Verified every endpoint against the official OpenAPI spec
(trade-api.gateway.uniswap.org/v1/api.json) and live API responses:
- swap.getStatus: GET /v1/swap_status -> GET /v1/swaps with required
chainId and txHashes[]/userOpHashes[] query; plural response shape
- delegation.check: POST /v1/check_delegation -> /v1/wallet/check_delegation
with walletAddresses[] and nested delegationDetails map response
- transaction.encode7702: -> POST /v1/wallet/encode_7702 requiring calls[],
smartContractDelegationAddress, hex-encoded wei values, and 4-byte
selector calldata; returns {requestId, encoded}
- order.getStatus: filter-based input (orderId/orderIds required,
32-byte hex), limit/cursor pagination, {requestId, orders[], cursor} output
- quote: require exactly one of slippageTolerance | autoSlippage, add
'urgent' urgency
- swap.create: accept and forward permitData together with signature
- new swappableTokens.get endpoint (GET /v1/swappable_tokens) from issue corsairdev#982
- replace type assertions in error-handlers and tests with instanceof and a
fully typed test context; drop leftover OAuth scaffold comment

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
Do not store permit authorization data in event logs.
Line 38 copies signature and permitData into the payload written through ctx.database. For a permitted swap, these values are signed authorization material before broadcast. A database reader or event-log export can expose them.
Build a redacted event payload. Add a test with permit fields that verifies neither field is logged.
