Shipping v2 API

The v2 shipping API is a PRO-gated read + webhook-subscription surface on top of WorldMonitor’s chokepoint registry and AIS tracking data.

All v2 shipping endpoints require X-WorldMonitor-Key (server-to-server). Browser origins are not trusted here — validateApiKey runs with forceKey: true.

Route intelligence

`GET /api/v2/shipping/route-intelligence`

Scores a country-pair trade route for chokepoint exposure and current disruption risk. Query parameters:

Param	Required	Description
`fromIso2`	yes	Origin country, ISO-3166-1 alpha-2 (uppercase).
`toIso2`	yes	Destination country, ISO-3166-1 alpha-2 (uppercase).
`cargoType`	no	One of `container` (default), `tanker`, `bulk`, `roro`.
`hs2`	no	2-digit HS commodity code (default `27` — mineral fuels).

Example:

GET /api/v2/shipping/route-intelligence?fromIso2=AE&toIso2=NL&cargoType=tanker&hs2=27

Response (200):

{
  "fromIso2": "AE",
  "toIso2": "NL",
  "cargoType": "tanker",
  "hs2": "27",
  "primaryRouteId": "ae-to-eu-via-hormuz-suez",
  "chokepointExposures": [
    { "chokepointId": "hormuz_strait", "chokepointName": "Strait of Hormuz", "exposurePct": 100 },
    { "chokepointId": "suez",   "chokepointName": "Suez Canal",        "exposurePct": 100 }
  ],
  "bypassOptions": [
    {
      "id": "cape-of-good-hope",
      "name": "Cape of Good Hope",
      "type": "maritime_detour",
      "addedTransitDays": 12,
      "addedCostMultiplier": 1.35,
      "activationThreshold": "DISRUPTION_SCORE_60"
    }
  ],
  "warRiskTier": "WAR_RISK_TIER_ELEVATED",
  "disruptionScore": 68,
  "fetchedAt": "2026-04-19T12:00:00Z"
}

disruptionScore is 0-100 on the primary chokepoint for the route (higher = more disruption).
warRiskTier is one of the WAR_RISK_TIER_* enum values from the chokepoint status feed.
bypassOptions are filtered to those whose suitableCargoTypes includes cargoType (or is unset).

Caching: Cache-Control: public, max-age=60, stale-while-revalidate=120. Errors:

Status	Cause
400	`fromIso2` or `toIso2` missing/malformed
401	API key required or invalid
403	`PRO subscription required`
405	Method other than `GET`

Webhook subscriptions

`POST /api/v2/shipping/webhooks`

Registers a webhook for chokepoint disruption alerts. Returns 200 OK. Request:

{
  "callbackUrl": "https://hooks.example.com/shipping-alerts",
  "chokepointIds": ["hormuz_strait", "suez", "bab_el_mandeb"],
  "alertThreshold": 60
}

callbackUrl — required, HTTPS only, must not resolve to a private/loopback address (SSRF guard at registration).
chokepointIds — optional. Omitting or passing an empty array subscribes to all registered chokepoints. Unknown IDs return 400.
alertThreshold — numeric 0-100 (default 50). Values outside that range return a 400 validation response with description alertThreshold must be between 0 and 100.

Response (200):

{
  "subscriberId": "wh_a1b2c3d4e5f6a7b8c9d0e1f2",
  "secret": "64-char-lowercase-hex-string"
}

subscriberId — wh_ prefix + 24 hex chars (12 random bytes).
secret — raw 64-char lowercase hex (32 random bytes). There is no whsec_ prefix. Persist it — the server never returns it again except on rotation.
TTL: 30 days on both the subscriber record and the per-owner index set. Only re-registration refreshes both, via an atomic pipeline (SET record with EX, SADD + EXPIRE on the owner index). rotate-secret and reactivate refresh the record’s TTL only — they do not touch the owner-index set’s expiry, so the owner index can expire independently if a caller only ever rotates or reactivates within a 30-day window. Re-register to keep both alive.
Ownership is tracked via SHA-256 of the caller’s API key (never secret — stored as ownerTag).

Auth: X-WorldMonitor-Key (forceKey: true) + PRO. Returns 401 / 403 otherwise.

`GET /api/v2/shipping/webhooks`

Lists the caller’s registered webhooks (filtered by the SHA-256 owner tag of the calling API key).

{
  "webhooks": [
    {
      "subscriberId": "wh_...",
      "callbackUrl": "https://hooks.example.com/...",
      "chokepointIds": ["hormuz_strait", "suez"],
      "alertThreshold": 60,
      "createdAt": "2026-04-19T12:00:00Z",
      "active": true
    }
  ]
}

The secret is intentionally omitted from list and status responses.

`GET /api/v2/shipping/webhooks/{subscriberId}`

Status read for a single webhook. Returns the same record shape as in GET /webhooks (no secret). 404 if unknown, 403 if owned by a different API key.

`POST /api/v2/shipping/webhooks/{subscriberId}/rotate-secret`

Generates and returns a new secret. The record’s secret is replaced in place; the old secret stops validating immediately.

{ "subscriberId": "wh_...", "secret": "new-64-char-hex", "rotatedAt": "2026-04-19T12:05:00Z" }

`POST /api/v2/shipping/webhooks/{subscriberId}/reactivate`

Flips active: true on the record (use after investigating and fixing a delivery failure that caused deactivation).

{ "subscriberId": "wh_...", "active": true }

Delivery format

POST <callbackUrl>
Content-Type: application/json
X-WM-Signature: sha256=<HMAC-SHA256(body, secret)>
X-WM-Delivery-Id: whd_<32 lowercase hex chars>
X-WM-Event: chokepoint.disruption

{
  "subscriberId": "wh_...",
  "chokepointId": "hormuz_strait",
  "score": 74,
  "alertThreshold": 60,
  "triggeredAt": "2026-04-19T12:03:00Z",
  "reason": "ais_congestion_spike",
  "details": { ... }
}

The delivery worker re-resolves callbackUrl before each send and re-checks against PRIVATE_HOSTNAME_PATTERNS to mitigate DNS rebinding. Delivery is at-least-once — consumers must handle duplicates via X-WM-Delivery-Id.

Verifying deliveries

Every delivery is signed so you can confirm it genuinely came from WorldMonitor. X-WM-Signature is sha256=<hex>, where <hex> is the lowercase-hex HMAC-SHA256 of the exact raw request body, keyed by the secret returned at registration. To verify: recompute sha256= + hex(HMAC_SHA256(key=secret, message=rawBody)) over the bytes exactly as received (do not re-serialize the JSON), and compare against X-WM-Signature in constant time. Use the secret string verbatim as the HMAC key — do not hex-decode it. Reject the delivery if the signatures differ.

import { createHmac, timingSafeEqual } from 'node:crypto';

// rawBody: the exact request body bytes; header: the X-WM-Signature value;
// secret: the value returned by RegisterWebhook (used verbatim as the key).
function verifyWorldMonitorWebhook(rawBody, header, secret) {
  const expected = 'sha256=' + createHmac('sha256', secret).update(rawBody).digest('hex');
  const a = Buffer.from(header ?? '');
  const b = Buffer.from(expected);
  return a.length === b.length && timingSafeEqual(a, b);
}

The signature contract is also published machine-readably as the chokepoint.disruption entry under webhooks in the OpenAPI spec.

Test your verification against a signed sample

A ready-to-verify sample delivery is published at /.well-known/webhook-sample.json. It carries a fixed sample secret, the exact raw body string, and the resulting signature. Recompute sha256= + hex(HMAC_SHA256(key=secret, message=body)) over the exact bytes of body and confirm it equals signature — if it matches, your verification will accept real deliveries. (The sample secret is a fixture; each live subscription gets its own secret from RegisterWebhook.)

const s = await (await fetch('https://www.worldmonitor.app/.well-known/webhook-sample.json')).json();
verifyWorldMonitorWebhook(s.body, s.signature, s.secret); // → true
