By default batches ClearBook + MakerWithdrawFunds(all) + CloseMakerBook into one tx for a clean one-signature exit. The book must end fully empty (enforced on-chain); if a phase is opted out and the book is non-empty on that dimension, returns 400. ## OpenAPI ````yaml /openapi.json post /v1/maker/close openapi: 3.0.3 info: description: >- REST API for the Archer Exchange — a high-performance Solana-based order book exchange. All monetary values (prices, sizes, fees) are returned as decimal strings for precision. ### Rate Limiting All endpoints are rate-limited via a token-bucket algorithm. When the limit is exceeded, the API returns `429 Too Many Requests`. ### Error Format All errors follow a consistent JSON format: ```json { "error": "ERROR_CODE", "message": "Human-readable description" } ``` ### Handling errors Every error falls into one of five actions. REST errors come back as `{"error": CODE, "message"}`. A transaction that fails on-chain reports `{"InstructionError": [index, {"Custom": code}]}`; codes are the `errors` list of the program IDL (`archer-sdk/idl/archer_v1.json`). When a build endpoint's preflight catches an on-chain error first, it returns `400 INVALID_PARAMS` with the reason in `message`. | Action | REST | On-chain (code) | |---|---|---| | **Retry as is**, with backoff | `RATE_LIMITED` (429), `SERVICE_UNAVAILABLE` (503), `INTERNAL_ERROR` (500); relay `OVERLOADED`, `PREFLIGHT_UNAVAILABLE`. Keep backing off on 429: 50 of them within a minute from one IP returns `BANNED` (403) for 10 minutes | none | | **Refetch, rebuild, retry**: the book or registry changed under you | | `LevelSizeMismatch` (527), `StaleSequenceNumber` (509), `SequenceNumberTooFarAhead` (522), `RegistryBooksMismatch` (525), `IncompleteMakerBooks` (513), `NoMatchingLiquidity` (507); relay status `expired` (re-sign with a fresh blockhash) | | **Reprice** | `CROSSES_SPREAD`, `SLIPPAGE_EXCEEDED` | `PostOnlyWouldCross` (524), `CrossingOrderLevels` (505), `InvalidPrice` (503), `SlippageToleranceExceeded` (703) | | **Resize** | `INSUFFICIENT_LIQUIDITY` (the body's `availableSize` is what fits) | `MakerBookSideFull` (528: cancel a level first), `InvalidSizeAtLevel` (506), `InsufficientBalance` (402) and SPL Token `1` (fund the account or shrink), `ZeroSwapAmount` (702) | | **Stop**: fix the request or the setup; retrying cannot help | `INVALID_PARAMS`, `MISSING_API_KEY` / `INVALID_API_KEY` (401), `FORBIDDEN`, `NOT_FOUND`, `MARKET_NOT_FOUND`, `METHOD_NOT_ALLOWED`; `MARKET_PAUSED` / `MARKET_FROZEN` until the market resumes | `UnauthorizedArcherAccountDelegate` (1001), `BuilderFeeExceedsAccountCap` (1003), `UnauthorizedMaker` (502), `MakerNotRegistered` (512), `PostOnlyRequiresLimitOrderBook` (526), `MarketNotActive` (107), `MarketFrozen` (114); any 200–399 code (wrong account wiring, a bug to report) | title: Archer Exchange API version: 1.0.0 servers: - description: Production url: https://api.archer.exchange - description: Staging url: https://api-staging.archer.exchange - description: Local url: http://localhost:8080 security: - apiKey: [] tags: - description: Discover and inspect available trading markets name: Markets - description: Token metadata for every mint Archer lists name: Tokens - description: Get price quotes before placing an order name: Quote - description: Build unsigned Solana transactions for swaps name: Orders - description: Build unsigned Solana transactions for limit orders name: Limit Orders - description: >- ArcherAccount — a wallet's delegated trading identity.
