Resolved picks are public; a still-pending pick's backed side is included for the authenticated Insider key. The full Pick of the Day track record: every published pick with its real outcome, plus the rolling hit rate. * `picks` lists every published pick, most recent last, each with its `outcome` and (for resolved, priced picks) the `return_per_100` on a \$100 stake. * `hit_rate` is the headline record: `wins`, `losses`, `decided` (wins + losses), and `pct` (wins / decided). `void` and `pending` picks are excluded from the rate. * `hit_rate.net_profit_usd`, `staked_usd`, and `roi_pct` model a flat \$100-per-pick strategy over resolved, priced picks. * `hit_rate.series` is the cumulative curve, one point per decided pick in ascending date order, ready to chart. Its last point equals the headline `net_profit_usd` and `pct` by construction. Resolved picks are the public record. A still-pending pick's backed side (`pick_outcome_label`) is included because the API key already proves Insider tier. ```bash theme={null} curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \ "https://api.0xinsider.com/api/v1/pick-of-the-day/archive" ``` Side-effect-free and ETag-cacheable.

Not a credit/price. directional_source: type: string enum: - live - degraded description: >- Which path produced the team-directional read on this response. Only present on endpoints that compute one (today: GET /api/v1/sports-edge-signals). "live" means the read RAN. "degraded" means it FAILED, so nothing was measured and the ranking fell back to raw conviction. The flag describes the READ, not its consequence: a read that ran and found nothing groupable also leaves the directional fields null, and that is honestly "live" -- the per-signal nulls already say "nothing to enrich here", so this snapshot-level flag carries only what they cannot, namely whether the read ran at all. A degraded response is cached on the shorter degraded TTL so it self-heals. Reported SEPARATELY from ranking_source because the two degradations are independent -- a smart-money DB miss weakens the ranking DATA, a directional failure removes a ranking WEIGHT -- and a consumer down-weighting a degraded response needs to know which input it lost. Omitted on endpoints that compute no directional read. ranking_source: type: string enum: - live - db_only description: >- Which ranking-data path produced this response. Only present on endpoints that can degrade a ranking (today: GET /api/v1/sports-edge-signals). "live" is the normal path (the current holder pile from the provider batch); "db_only" is the degraded fallback (a truthful but weaker trader_markets ranking) served when the live sharp-money ranking batch is unavailable (a smart-money DB read failure, not a Polymarket outage) and cached on a shorter TTL, so a consumer can down-weight or skip it. Omitted on endpoints that never degrade. PickOfTheDayArchiveEntry: type: object required: - pick_date - matchup - category - outcome properties: pick_date: type: string format: date description: The pick's local publication date (YYYY-MM-DD). matchup: type: string description: Human-readable matchup (e.g. "Portugal vs. Uzbekistan"). category: type: string description: Market category (e.g. "Soccer"). image_url: type: string description: >- Provider (Polymarket Gamma) market thumbnail URL (markets.image); omitted (not null) when the market has no image. Public regardless of the backed-side gate, so present for pending rows too. pick_outcome_label: type: string nullable: true description: >- The backed side's outcome label. Omitted for a still-pending pick when the request is not from an authenticated Insider key. top_grade: type: string nullable: true description: >- Best grade among the proven smart-money holders on the backed side (S, A, B, C, D, F). outcome: type: string enum: - pending - win - loss - void description: >- Settlement outcome of the backed side; 'pending' until the market resolves. outcome_display: type: string description: >- Pre-formatted settlement status for display: "Win" / "Loss" / "Void" / "Pending" -- the outcome enum above as a label, from the same formatter the pick payload's outcome_display uses. Convenience only; outcome is the source value. return_per_100: type: number description: >- Gross return on a $100 stake on this resolved pick: a win returns 100 / backed_price, a loss returns 0, a void refunds 100. A loss always returns 0 (the whole stake is lost regardless of price). Omitted (not null) only for a still-pending pick or a resolved WIN with no frozen price (a win's payout needs the price); mirrors the backend skip-when-absent behavior and the route-client optional (non-nullable) schema. payout_display: type: string description: >- Pre-formatted return_per_100 as USD with cents: "$200.00". Present exactly when return_per_100 is -- it is formatted from that already-gated value -- so it is omitted for a still-pending pick, an unpriced win, and any pick whose backed side is withheld. Convenience only; return_per_100 is the source value. PickOfTheDayHitRate: type: object required: - wins - losses - decided - pct - void - pending - net_profit_usd - staked_usd - roi_pct - net_profit_display - roi_display - win_rate_display properties: wins: type: integer description: Number of decided picks that won. losses: type: integer description: Number of decided picks that lost. decided: type: integer description: Number of decided picks (wins + losses); excludes void and pending. pct: type: number description: >- Rolling hit rate as a percentage (wins / decided * 100, to 1 decimal); 0 when none are decided. void: type: integer description: Number of picks that resolved void (excluded from the hit rate). pending: type: integer description: >- Number of picks still pending resolution (excluded from the hit rate). net_profit_usd: type: number description: >- Cumulative profit (USD) of a $100/pick strategy over decided picks with a valuation: a win pays 100/backed_price - 100, a loss pays -100 (always, price-independent), a void pays 0. Only a resolved WIN with no frozen price is excluded (its payout is unknowable); a priceless loss still books -100. staked_usd: type: number description: >- Total staked (USD) = 100 * count of decided picks with a valuation: every loss (always) plus every priced win. Void (refunds the stake) and a priceless win (unknowable payout) are excluded. roi_pct: type: number description: >- Return on the staked amount as a percentage (net_profit_usd / staked_usd * 100, to 1 decimal); 0 when nothing is staked. net_profit_display: type: string description: >- Pre-formatted net profit for display, e.g. "+$100" / "-$40". Whole dollars, signed, round-then-signed so a rounds-to-zero record reads "+$0" (never "-$0"). Convenience only; net_profit_usd is the source value. roi_display: type: string description: >- Pre-formatted ROI for display, e.g. "+8.3%" / "-20.0%". One decimal, signed, round-then-signed so a rounds-to-zero record reads "+0.0%" (never "-0.0%"). Convenience only; roi_pct is the source value. win_rate_display: type: string description: >- Pre-formatted win rate for display, e.g. "92.3%". One decimal, unsigned. Convenience only; pct is the source value. series: type: array description: >- Cumulative track-record series, one point per decided (win/loss) pick in ascending pick_date order (void and pending add no point). The last point's net_profit_usd and hit_rate_pct equal the headline net_profit_usd and pct by construction. Empty when nothing is decided. items: type: object required: - date - net_profit_usd - hit_rate_pct properties: date: type: string format: date description: The decided pick's publish date (YYYY-MM-DD). net_profit_usd: type: number description: >- Running cumulative $100/pick profit (USD) through this pick (every loss and every priced win are booked; only an unpriced WIN carries it forward unchanged). hit_rate_pct: type: number description: >- Running rolling hit rate (wins / decided * 100, to 1 decimal) through this pick. ApiError: type: object required: - object - error - meta properties: object: type: string const: error error: type: object required: - code - message properties: code: type: string enum: - bad_request - invalid_api_key - subscription_required - forbidden - not_found - account_locked - rate_limited - rate_limit_unavailable - internal_error message: type: string doc_url: type: string nullable: true param: type: string nullable: true retry_at: type: string format: date-time nullable: true description: >- The recommended next retry instant (RFC3339). Present on every retryable error (reason=pick_not_released, code=rate_limited, code=rate_limit_unavailable, reason=read_model_warming) and omitted otherwise. Always in the future. For pick_not_released it has two regimes: before the 11:00 UTC operating-window start, before a selected pick's stored release, or after a terminal skipped day, it is an exact floor and nothing can publish first. When a publish is overdue or the selector is still hunting inside the operating window, it is a bounded cadence (~60s), not a lower-bound promise; a pick may publish before it. Schedule one request and do not poll. Prefer Retry-After for the duration because it is immune to client clock skew. reason: type: string enum: - cursor_expired - unknown_endpoint - pick_not_released - trader_not_tracked - read_model_warming nullable: true description: >- ADDITIVE (#7209). The specific, actionable cause behind `code`, when there is one more specific than the code itself. `code` keeps its published values, so existing clients are unaffected; new clients branch on `reason`. Omitted when the code already says everything we know. pick_not_released: no Pick of the Day is published for the current product day; schedule one request against retry_at instead of polling. unknown_endpoint: the PATH is not a route on this API -- read GET /api/v1, do not retry. trader_not_tracked: the wallet is real and the URL is right, but the trader is outside the HOT/WARM sync tiers -- stop asking for this wallet. cursor_expired: pagination went stale mid-walk -- re-request the first page and continue. read_model_warming: the requested endpoint cannot serve its read model yet; exact causes are endpoint-specific and can include a cold or contended refresh or a dependency that prevented refresh. Consult that endpoint's contract, retry only this route after the interval, and do not infer dependency health from this reason. meta: $ref: '#/components/schemas/ResponseMeta' responses: Unauthorized: description: Missing or invalid API key content: application/json: schema: $ref: '#/components/schemas/ApiError' SubscriptionRequired: description: Active Insider subscription required content: application/json: schema: $ref: '#/components/schemas/ApiError' Forbidden: description: Account access denied content: application/json: schema: $ref: '#/components/schemas/ApiError' RequestTimeout: description: >- Request exceeded the server's 30-second transport timeout.

(1) 100 requests/minute per user (sliding window), on every authenticated route. (2) On the BATCH routes only: 2500 batch item units/minute per user, reserved before any item is executed. A batch with N requested items costs N item units, including duplicate and invalid items. 2500 = 100 requests x 25 items per batch, which is the most item work a key can buy through the request limiter at all: a caller may spend their entire 100-request minute on full 25-item batches without the item budget being what stops them. The REQUEST budget is the effective ceiling, and batching is never the more expensive choice. The item budget still denies at a sliding-window boundary (both counters carry the previous window forward with a floor, and the item counter runs 25x the request counter), so honor a 429 from either. Over-quota batches return 429 with Retry-After before any item work is done. headers: Retry-After: description: Seconds until rate limit resets. schema: type: integer X-RateLimit-Limit: schema: type: integer X-RateLimit-Remaining: schema: type: integer X-RateLimit-Reset: schema: type: integer X-Request-Id: schema: type: string content: application/json: schema: $ref: '#/components/schemas/ApiError' RateLimitUnavailable: description: >- Redis-backed authenticated rate limiter unavailable; retry after the per-process outage cooldown headers: Retry-After: description: >- Seconds until the middleware will probe the Redis-backed rate limiter again. schema: type: integer X-Request-Id: schema: type: string content: application/json: schema: $ref: '#/components/schemas/ApiError' securitySchemes: bearerAuth: type: http scheme: bearer description: >- API key authentication.
