The simplified, key-first surface for Routing Studio. The customer never sees a “preference” object — the server find-or-creates a hidden per-key preference under the hood and ensures the binding row points at it. Reach for this endpoint when you’re tuning a single API key. Reach for /api/v1/routing-preferences when you want a shared rule set that spans many keys or acts as a team default.

​
Authentication

Requires a Bearer token with the billing API key scope and access to the key (caller owns it, or has access through the active org).

​
GET

Read the per-key rules and the resolved binding state. 
curl https://www.hitheo.ai/api/v1/keys/{id}/routing-rules \
  -H "Authorization: Bearer $THEO_API_KEY"

const snap = await theo.routingRules.get(keyId);
console.log(snap.active);          // true if these rules drive completions today
console.log(snap.shared_binding);  // populated when the key is bound to a shared preference

​
Response

{
  "key_id": "key_abc",
  "rules": [
    {
      "id": "r_a4b8c01x9y",
      "pattern": "\\b(clause|provision|indemnity|warranty)\\b",
      "target_mode": "think",
      "confidence": 0.92,
      "description": "Contract terms get the analytical engine."
    }
  ],
  "examples": [
    { "prompt": "Look at this clause", "expected_mode": "think" }
  ],
  "confidence_floor_overrides": { "think": 0.65 },
  "active": true,
  "shared_binding": null
}
  • active: true — these rules drive completions on this key right now.
  • active: false — the key inherits a default (or is bound to a shared preference); rules are still editable but inactive until saved or until the shared binding is cleared.
  • shared_binding — populated when the key is bound to a shared preference instead of its hidden row. Render the shared rules read-only and offer an “Override on this key” button.

​
PUT

Replace the per-key rules / examples / overrides. The route find-or-creates the hidden preference and ensures the binding points at it.
​
rules
object[]
Up to 50 rules. Same shape as routing-preferences.
​
examples
object[]
Up to 30 few-shot examples.
​
confidence_floor_overrides
object
Per-mode confidence-floor overrides.
curl -X PUT https://www.hitheo.ai/api/v1/keys/{id}/routing-rules \

await theo.routingRules.set(keyId, {
  rules: [
    {
      pattern: "\\b(clause|provision|indemnity|warranty)\\b",
      target_mode: "think",
      confidence: 0.92,
      description: "Contract terms get the analytical engine.",
    },
  ],
  examples: [{ prompt: "Look at this clause", expected_mode: "think" }],
});

​
DELETE

Clear the per-key rules: drops the binding so the resolution cascade falls back to org default → user default → none, and deletes the hidden preference row. Existing bindings to a non-hidden (shared) preference are left alone. 
curl -X DELETE https://www.hitheo.ai/api/v1/keys/{id}/routing-rules \
  -H "Authorization: Bearer $THEO_API_KEY"

​
Errors

  • 400 routing_preference_invalid — Validation failure (vendor name, uncompilable regex, etc.).
  • 404 not_found — Key doesn’t exist, is revoked, or isn’t accessible to the caller.
