The figures match `performance` on `/trader-stats/positions`. `performance` is null for a venue whose stats come only from the full positions build; read them from `/trader-stats/positions` there. **Public endpoint — no authentication required** (trader data is public). Rate-limited per client IP. Responses are cacheable at the edge. ## OpenAPI ````yaml /openapi/data-api.yaml get /trader-stats/summary/{wallet_address} openapi: 3.1.0 info: title: Kairos Data API version: 1.0.0 summary: >- The full Kairos data plane — markets, candles, trades, search, discover, sports, trader analytics, and PnL. description: | The Kairos Data API at `data.kairos.trade` is the platform's primary data plane: market metadata and prices, OHLCV candles, live venue trade proxies, normalized trade history, full-text search, discovery feeds, the sports catalog, public trader analytics, and account PnL. ## Authentication Most endpoints accept a Kairos **API key** (`X-Client-Id` + `X-Api-Key` + `X-Api-Secret`, all three) or a first-party session JWT. Endpoints tagged `public` (trader analytics, provider configs, several sports feeds) need no credentials at all. Some endpoints additionally require an API-key **scope** (`trade:read`, `position:read`) — stated per operation. For high-volume market-data consumption (candles/trades/metadata at scale), prefer the dedicated **Market Data API** at `md.kairos.trade` — it has higher budgets, ETag caching, and a binary candle format. ## Rate limits Rate limits use a sliding window keyed on the authenticated user (JWT `sub`) or, for anonymous callers, the trusted client IP. Routes belong to a named **bucket** (`x-kairos-bucket`) whose per-minute budget is shared by every route in it; routes with no bucket run under the service default of 100/minute. `x-kairos-rate-limit` states the bucket's compile-time default — operators can raise or lower a bucket at runtime, so treat the documented number as the baseline, not a contract. 429 responses carry `Retry-After` and `X-RateLimit-*`. ## Conventions - Prices are on the **0–100 cents scale** unless a field says otherwise (trader-analytics position/trade prices use the 0–1 scale; each field's description states its scale). - Errors: `{"detail": ""}` for handler errors; FastAPI's standard validation envelope for 422s. Errors surfaced from a venue adapter instead use `{"error", "provider", "operation", "message"}` — see `DataProviderError`. Unhandled failures always return the generic 500 body; internal details are logged, never returned. - Every request body is capped at 8 MiB service-wide (413). contact: name: Kairos url: https://app.kairos.trade/docs/api-reference termsOfService: https://kairos.trade/terms servers: - url: https://data.kairos.trade description: Production - url: https://staging-data.kairos.trade description: Staging security: - apiKeyClientId: [] apiKeyKey: [] apiKeySecret: [] paths: /trader-stats/summary/{wallet_address}: get: tags: - Trader Analytics summary: Get a trader's performance stats without the position list description: > Returns the stats a trader profile's header and stats panel show (PnL, ROI, win rate, volume, position counts, positions_value) without the position list, so they render before the positions page.
