主流 API プロトコルとの互換性（itick.org 等）
| Protocol / Standard | Scope | Status |
|---|---|---|
itick.org specification | REST quotes / candles / depth / ticks and WebSocket streaming (identical paths, parameters and JSON payloads) | Supported (drop-in replacement by changing Base URL & Token) |
| Additional market data protocols | Standardized adapters for other widely used financial market data APIs | In progress (continuously being added) |
- Multi-protocol compatibility: currently supports the full
itick.orgREST and WebSocket specification (more mainstream market data protocols are being added). Simply replace the base URL with this site's address. - Only GET requests are supported, on paths starting with
stock,forex,crypto,indices,future,fund,symbol,marketornews. - FIX access, S3 file downloads and AI agent interfaces are not provided.
- Market data is briefly cached (see rate limits and freshness), and you may see extra errors caused by limits and token status (429, 403).
- The data you can call depends on the plan you subscribe to.
