Clients keep polling this same endpoint after expiry instead of switching to another endpoint. Looked up from the same snapshot as `GET /v1/public/binary/info`. Returns successfully even before the result is published; it never responds with a "result not ready" state. Returns `RESOURCE_NOT_FOUND` when the symbol does not exist, is not a Predict symbol, has not yet opened for trading, or has fallen outside the most recent 300 rounds. Whether the result has been published is determined only by whether `result_committed_at` has a value, never by `status`, `s1`, or `outcome`. ## OpenAPI ````yaml orderly.openapi get /v1/public/binary/info/{symbol} openapi: 3.0.1 info: title: EVM description: '' version: 1.0.0 servers: - url: https://api.orderly.org description: Mainnet - url: https://testnet-api.orderly.org description: Testnet security: [] tags: - name: public - name: private paths: /v1/public/binary/info/{symbol}: get: tags: - public summary: Get Orderly Predict round info for one round description: > `GET /v1/public/binary/info/{symbol}` Returns the full lifecycle information for a single Predict round, from when it opens for trading through result publication.

Never constructed by the client. example: product_type: type: string description: >- Always `BINARY`. Clients use this field to classify the product and must not parse it from the symbol. example: BINARY status: type: string description: >- Round status. Only `ACTIVE`, `DELISTING`, `RECYCLING`, or `DELISTED`; trading controls never set another value. enum: - ACTIVE - DELISTING - RECYCLING - DELISTED activated_at: type: integer nullable: true description: When the round opened for trading (t_active). Null before it opens. observation_start_at: type: integer description: t0, the time boundary used to record S0. expire_at: type: integer description: >- t1, the expiry boundary for ordinary order placement, editing, and cancellation. s0: type: number nullable: true description: >- S0. Null before t0 or before it has been recorded. This is the only S0 field; there is no `strike_price` alias. index_price_symbol: type: string description: >- The underlying's Index symbol, formatted as `PERP_{underlying}_USDC`. example: PERP_BTC_USDC fee_model: type: string description: >- Always `BINARY_PROBABILITY`, meaning each fill is charged in USDC as `C x r x p x (1 - p)`, where `r` is the account's Predict maker or taker rate in bps divided by 10000. example: BINARY_PROBABILITY s1: type: number nullable: true description: S1. Always null before the result is published. outcome: type: string nullable: true description: >- `UP`, `DOWN`, or `TIE` once the result is published; null before that. `S1 > S0` is `UP`, `S1 < S0` is `DOWN`, `S1 = S0` is `TIE`. enum: - UP - DOWN - TIE settlement_price_per_share: type: number nullable: true description: >- Settlement price per share once the result is published. 1 or 0 for `UP`/`DOWN`; 0.5 per share on both UP and DOWN for `TIE`. Null before the result is published. This value is always the UP-book settlement price `R`; an UP position settles at `R` per share and a DOWN position settles at `1 - R` per share. result_committed_at: type: integer nullable: true description: >- When the result was first published. Null before that. Does not by itself mean a user's funds have settled; see `GET /v1/position_history`. rule_version: type: string description: Always `binary-v1`. example: binary-v1 quote_min: type: number description: Minimum order price.

Currently fixed at `5`. funding_period: type: number description: >- Funding period in hours, present when the corresponding configuration is available. Predict does not support liquidation, so `std_liquidation_fee`, `liquidator_fee`, `claim_insurance_fund_discount`, and `liquidation_tier` are omitted rather than zero-filled. cap_funding: type: number floor_funding: type: number interest_rate: type: number cap_ir: type: number floor_ir: type: number imr_factor: type: number deviation_factor: type: number mark_index_price_deviation_floor: type: number mark_index_price_deviation_cap: type: number BinaryPriceEvidence: type: object nullable: true description: >- Null before the result is published.
