One schema across native HL perps, HIP-3 builder markets, HIP-4 outcome contracts and HL spot. **Base URL:** `https://api.ironflow.sh` **Authentication:** Read endpoints work without a key (keyless access) or with a Bearer token in the `Authorization` header. Writes always need a key. ``` Authorization: Bearer if_your_api_key ``` Get a free key at https://ironflow.sh/key. **Access levels:** | Access | Requests per minute | History | Max range per request | |---|---|---|---| | No key | 10 per IP | 24 hours | 1 hour | | Free key | 60 | 30 days | 6 hours | | Explorer | 100 | 90 days | 24 hours | | Builder | 1,000 | 1 year | 7 days | | Enterprise | 10,000 | full | unlimited | Without a market filter, high-volume endpoints allow at most 4 hours per request. A header that is present but malformed returns 401; keyless access applies only when no `Authorization` header is sent. **Data availability:** fills and trades cover a rolling 12 months; other datasets start later (funding 2025-09-27, open interest and mark prices 2026-04-29). **Timestamps:** All timestamps are Unix milliseconds (int64). **Pagination:** Paginated endpoints return a `cursor` in `pagination.next_cursor`. Pass it as the `cursor` query parameter to fetch the next page. When `pagination.has_more` is `false`, you have reached the last page. contact: name: Ironflow Support url: https://ironflow.sh servers: - url: https://api.ironflow.sh description: Production security: - bearerAuth: [] - {} tags: - name: Market Data description: Historical tick-level market data stored in ClickHouse. - name: Analytics description: Aggregated analytics endpoints (Builder tier and above). - name: Cohorts description: Predefined and custom address groups for filtering market data. - name: Info Proxy description: >- Cached passthrough to the Hyperliquid Info API.

Computed on the fly by ClickHouse — no separate candle table. Includes buy/sell volume split. Supported intervals: `1m`, `5m`, `15m`, `1h`, `4h`, `1d` Without `from`, the window covers `limit` candles back from now (at most 30 days), bounded by your access level's history depth. So 24 hourly candles return the last 24 hours, with or without a key. operationId: listCandles parameters: - $ref: '#/components/parameters/source' - name: market in: query required: true description: Market symbol (e.g. `BTC-PERP`). schema: type: string example: BTC-PERP - name: interval in: query required: true description: Candle interval. schema: type: string enum: - 1m - 5m - 15m - 1h - 4h - 1d example: 1h - $ref: '#/components/parameters/base_market' - $ref: '#/components/parameters/issuer' - $ref: '#/components/parameters/from' - $ref: '#/components/parameters/to' - $ref: '#/components/parameters/limit' - $ref: '#/components/parameters/cursor' responses: '200': description: Paginated list of candles. content: application/json: schema: $ref: '#/components/schemas/CandleList' example: data: - source: hyperliquid market: BTC-PERP issuer: '' base_market: BTC-PERP interval: 1h timestamp: 1718398800000 open: '67400.00' high: '67500.50' low: '67380.00' close: '67432.10' volume: '1523.45' trade_count: 8412 pagination: next_cursor: MTcxODM5ODgwMDAwMA== has_more: true '400': $ref: '#/components/responses/QueryWindowExceeded' '401': $ref: '#/components/responses/Unauthorized' '403': $ref: '#/components/responses/Forbidden' '429': $ref: '#/components/responses/RateLimited' '500': $ref: '#/components/responses/InternalError' '504': $ref: '#/components/responses/QueryTimeout' components: parameters: source: name: source in: query description: Venue identifier. Defaults to `hyperliquid`. schema: type: string enum: - hyperliquid default: hyperliquid example: hyperliquid base_market: name: base_market in: query description: > Base market symbol, stripped of any issuer namespace (e.g. `GAS-PERP`). Matches both native HL markets (`market` == `base_market`) and every HIP-3 builder-deployed market with that base (e.g. `flx:GAS-PERP`). Use together with `issuer` to scope to a single builder, or alone to query across all issuers of the same base symbol. schema: type: string example: GAS-PERP issuer: name: issuer in: query description: > HIP-3 builder/issuer namespace (e.g. `flx`). For native HL perps the issuer is the empty string; do not combine `issuer=""` with this filter — omit the parameter instead. Commonly paired with `base_market` to disambiguate a builder-deployed market from its native counterpart. schema: type: string example: flx from: name: from in: query description: >- Start time as Unix milliseconds.
