For alerts scoped to only the assets YOU subscribe to, use the authenticated `GET /v1/me/alerts` instead. ## OpenAPI ````yaml https://api.pegana.xyz/openapi.json get /v1/alerts openapi: 3.1.0 info: title: Pegana API description: >- The peg-risk oracle for Solana. Read real-time peg state, history, alerts, and delivery health across 26 active mainnet assets 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`). contact: name: Rafael Souza email: rafael@pegana.xyz license: name: MIT identifier: MIT version: 0.1.0 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.

Lets the /events feed show each transition's spread magnitude without a second per-row lookup. `None` for older rows where the `alerts.discount` column is NULL — the client falls back to the asset's live spread, so the field is additive (omitted, never `null`). dispatched_at: type: - string - 'null' format: date-time description: >- `null` until the dispatcher delivers this alert to its first fan-out target (Telegram or a webhook subscriber); stamped once at least one delivery succeeds. Stays `null` when the alert matched no subscriber — nothing was delivered — so a `null` here means "not delivered", NOT "delivery failed". Distinct from `detected_at` (when the engine saw the transition) and from on-chain commit (a separate evidence path). from_state: $ref: '#/components/schemas/PegState' id: type: string format: uuid monitoring_only: type: boolean description: >- True for a released `monitoring_only` (beta) asset — its calibration is provisional, so this alert should be read as experimental.

Branch on this, never on `message`. message: type: string description: >- Human-readable explanation. NOT stable — for humans/logs; do not parse. Calibration: type: string description: >- Calibration status of an asset (and of an alert that asset emitted). - `provisional` — a "beta" asset: released and alerting publicly, but its thresholds are not yet validated over a full post-launch calibration window. Equivalent to `monitoring_only=true`. Read its alerts as experimental. - `calibrated` — a fully calibrated asset that counts in the launch denominator. This is the SAME vocabulary the dispatcher emits on the webhook canonical event (`"calibration":"provisional"|"calibrated"`), so a machine consumer reading both the webhook fan-out and the REST read surfaces sees one word for the concept instead of `calibration` there and `monitoring_only` here. enum: - provisional - calibrated 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 ````
