Read real-time peg state, history, alerts, and delivery health across the live mainnet asset universe spanning 6 classes — LSTs, fiat / CDP / delta-neutral / yield-bearing / FX stables, and a leveraged synthetic. Some assets are flagged `monitoring_only` (beta): their alerts are live but the calibration is provisional. Public read endpoints require no API key but ARE rate-limited per IP (300/min global, 10/min on /v1/audit.csv); exceeding the limit returns 429 with a Retry-After header. User-scoped /v1/me/* routes require a JWT obtained via Telegram Login. Every state transition emits a public receipt at /v1/audit/{id} with the methodology version, frozen inputs, and an on-chain SPL Memo commit (SAS deferred per ADR-0004 — SPL Memo gives 90% of the value). EVERY error response across the API is JSON — the envelope is `{error, message, asset?}` (the `ApiError` schema); branch on the stable `error` code, never on `message`. Malformed request bodies surface as `{error:"invalid_body"}`. Any endpoint may also return 500 `{error:"internal"}` on an unexpected server error. Value conventions: monetary and ratio amounts are exact decimal STRINGS (parse with a decimal library, never a float) with trailing zeros trimmed; USD aggregate fields (e.g. `market_cap`, `loop_exposure_usd`, `liquidatable_usd`) are rounded to the cent while price/discount signal fields keep full precision. All timestamps are RFC3339 UTC with millisecond precision and a `Z` suffix (`2026-07-24T15:33:14.545Z`). Every response carries an `x-request-id` header (quote it when reporting an issue) and the rate-limit budget as `RateLimit-Limit` / `RateLimit-Remaining` / `RateLimit-Reset` (mirrored as `X-RateLimit-*`); a 429 also sets `Retry-After`. contact: name: Rafael Souza email: rafael@pegana.xyz license: name: MIT identifier: MIT version: 1.0.0 servers: - url: https://api.pegana.xyz description: Production security: [] tags: - name: Health description: Liveness and readiness probes - name: Assets description: Public read access to asset state, history, and metadata - name: Alerts description: Global feed of state transitions - name: Stats description: Aggregate counters and delivery health - name: Auth description: Telegram Login Widget → JWT - name: Me description: Authenticated user profile and preferences - name: Subscriptions description: User alert subscriptions - name: Webhooks description: User-managed Ed25519-signed webhooks - name: WebSocket description: Live state stream - name: audit description: >- Public receipts for alerts — methodology version, inputs frozen, replay bundles.

The PRICE-ORACLE confidence-interval signal (conf/price ratio) — the field integrators should gate automation on alongside `state`. Mirrors the list endpoint's `confidence`. Collapses to `unknown` when the feed is stale (same as `state`), so a frozen feed cannot read as confidently pegged. Omitted only when no snapshot carries a confidence value (non-Pyth-dependent assets). discount: type: string intrinsic_usd: type: string market_usd: type: string since: type: string format: date-time description: |- Timestamp of the most recent transition into the current state. Equals the current snapshot timestamp if the engine has only ever observed one state for this asset. stale: type: boolean description: >- `true` when `updated_at` is older than the 15-minute freshness bound the list/detail endpoints enforce — i.e. the feed has likely frozen. Unlike list/detail, `/state` still returns the last value rather than 404-hiding it; read this flag to fail safe. Consumers needing a tighter bound can derive their own from `updated_at`. state: $ref: '#/components/schemas/PegState' state_reason: type: - string - 'null' description: >- Advisory machine-readable reason for the current state (mirrors `discount_snapshots.state_reason` and `Receipt.state_reason`). **Emitted today:** - `premium_sanity` — engine NAV-sanity override: smoothed discount exceeded the premium-sanity bound, state forced to UNKNOWN (intrinsic anchor suspect). - `stale_source` — API layer: feed is >15 min stale, state collapsed to UNKNOWN; no fresh discount snapshot exists. **Reserved — not yet emitted (planned for depth-gate / oracle-crosscheck work):** `no_oracle_crosscheck | intrinsic_unavailable | shallow_market | nominal`. Omitted when null. updated_at: type: string format: date-time description: >- Timestamp the current snapshot was computed (the latest `discount_snapshots.ts`). Distinct from `since` (state-transition time): this is the FRESHNESS signal. The engine stops writing snapshots when a feed goes stale ("missing data is not confirming data" — H8), so a frozen `updated_at` is exactly how a stale/frozen feed surfaces on this endpoint. ApiError: type: object required: - error - message properties: asset: type: - string - 'null' description: The offending asset symbol, present only for asset-scoped errors. error: type: string description: Stable, machine-readable code. Branch on this, never on `message`. message: type: string description: >- Human-readable explanation. NOT stable — for humans/logs; do not parse. PegState: type: string description: >- Class-aware peg state. Mirrors the engine `PegState` enum and the `peg_state` Postgres enum. Used for `state`, `from_state`, and `to_state` fields across the API. The state is CLASS-AWARE: an LST reading a −1.4% discount (normal unstaking spread) is `PEGGED`, while a fiat stable at far less would be `DRIFT`. Trust this value directly rather than imposing a naive discount cut. enum: - PEGGED - DRIFT - DEPEG - CRITICAL - BLACK_SWAN - UNKNOWN ````
