/iblai-vibe-agent-billing
Add the agent Billing tab -- set LLM spend limits for this agent
and its users, and see how much has been used. Two sub-tabs match the
backend's agent-level scopes: This Agent (the agent's own spend
cap) and Per User (explicit per-user limits on this agent, with
the user picked through a platform-user search). Each limit has an
enable toggle, a usage bar (spent / % used / remaining), a spend
amount with a reset interval (day/week/month/year), an enforcement
mode (Block Requests or Alert Only), and comma-separated
alert thresholds at which admins get a near-limit alert. Enforcement
is server-side — a blocked request is refused with a 429 /
spend_cap_exceeded error until the period resets. This is one tab
in the wider agent-settings family. All tabs share the same
AgentSettingsProvider wrapper.
Common setup (brand, conventions, env files, verification): see docs/skill-setup.md.
Prerequisites
- Auth must be set up first (
/iblai-vibe-auth) - MCP server + skills configured (
@iblai/mcpin.mcp.json) AgentSettingsProvidermust wrap the route (see/iblai-vibe-agent-settingStep 2 if not already set up)- Ask the user for a real
mentorId(agent UUID). Do NOT invent one. - The spend-cap endpoints are RBAC-gated admin endpoints — a user without access sees a friendly "no access" panel per sub-tab (403).
Step 1: Check Environment
Before proceeding, check for an iblai.env in the project root. Look for
PLATFORM, DOMAIN, and TOKEN variables. If the file does not exist or
is missing these variables, tell the user:
"You need an iblai.env with your platform configuration. Download the
template and fill in your values:
curl -o iblai.env https://raw.githubusercontent.com/iblai/vibe/refs/heads/main/iblai.env"
Step 2: Mount AgentSpendCapsTab
// app/(app)/agents/[mentorId]/billing/page.tsx
"use client";
import { AgentSpendCapsTab } from "@iblai/iblai-js/web-containers/next";
export default function AgentBillingPage() {
return (
<div className="flex h-full flex-col bg-white">
<AgentSpendCapsTab />
</div>
);
}
AgentSpendCapsTab reads tenantKey and mentorId from
AgentSettingsProvider. No props are required for the standard mount.
Step 3: Customize Labels (Optional)
import { AgentSpendCapsTab } from "@iblai/iblai-js/web-containers/next";
<AgentSpendCapsTab
labels={{
header: { title: "Spend limits" },
subTabs: { agent: "Agent limit", users: "User limits" },
}}
/>;
Step 4: Use MCP Tools for Customization
get_component_info("AgentSpendCapsTab")
get_component_info("SpendCapUsage")
get_component_info("AgentSettingsProvider")
<AgentSpendCapsTab> Props
Import from @iblai/iblai-js/web-containers/next.

What the tab renders
- Header — "Billing" title and "Set spend limits for this agent and its users, and see how much has been used."
- This Agent / Per User sub-tabs — the two agent-level scopes. The tab ratchets its height so switching sub-tabs never shrinks the dialog it is hosted in.
- No-access state — when the current user lacks permission for a scope's endpoints (403), that sub-tab's content is replaced by a "no access" notice.
Shared spend-cap editor (both scopes)
Both sub-tabs edit a cap through the same SpendCapForm:
- Enable toggle — "Put a ceiling on AI spend…" capability gate. While on, everything the limit covers counts toward the amount; fields collapse when toggled off. The flag rides along on save.
- Usage strip (saved caps only) — "Daily/Weekly/Monthly/Yearly Usage" with a progress bar (blue, amber at ≥80%, red when exceeded) and Spent / % of limit used / Remaining figures, plus Disabled / Alert only / Exceeded badges as applicable.
- Spend Limit (USD) — positive decimal; sent as a 2-decimal string.
- Resets Every — Day / Week / Month / Year.
- When the Limit Is Reached —
Block Requests(new chat and training requests are refused until the period resets) orAlert Only(requests continue; admins are alerted). - Alert At (% of Limit) — comma-separated percentages (default
80, 95) at which admins get a near-limit alert. - Delete Limit (saved caps only) — confirmation dialog before removal. Save creates the cap on first save and updates it after (the PUT is an upsert).
- Until a cap exists the form shows "No spend limit configured yet — set an amount and save to create one."
This Agent sub-tab
The agent's own singleton spend cap — everything spent on this agent by anyone counts toward it.
Per User sub-tab
Explicit (user, agent) limits — "Limit what specific users can spend on this agent."
- Table — User (email-first, linked to the same profile viewer as
the Management tab; clicking the row opens it too), Limit
(
$2.00 / Week), Status (direct enable toggle that saves immediately, plus Exceeded / Alert-only badges), and a per-row actions menu (Edit / Delete). - Add User Limit — opens the New User Limit modal: pick the user through a debounced platform-user search (min 2 characters, email-only options — no free-text usernames), then fill the same spend-cap form. Edit mode skips the picker and goes straight to the form for the cap's user.
- Delete — confirmation dialog showing the user's email.

Important Notes
- Redux store: Must include
mentorReducerandmentorMiddleware initializeDataLayer(): 5 args (v1.2+)@reduxjs/toolkit: Deduplicated via webpack aliases innext.config.ts- Peer deps:
sonnerand@iblai/iblai-web-mentormust be installed (pnpm add sonner @iblai/iblai-web-mentor) - Shared provider:
AgentSettingsProvidermust wrap the route at a layout level. See/iblai-vibe-agent-settingStep 2 for the full snippet. - First-run 404 is normal: the singleton GETs 404 until a cap is first saved — that is the documented "no cap configured" state, not an error. The first Save creates the row.
- Counters are read-only:
current_spend_usd,remaining_usd, andis_exceededare reconciled server-side and only rendered — never submitted. Admins writeinterval_type,max_cost_usd(decimal string),enforcement,alert_thresholds,enabled. - PUT is an upsert: the status toggles in the tables save
immediately by re-submitting the cap's current fields with the
flipped
enabledflag. - Username key, email display: per-user caps are keyed by
usernamein the API; the UI deliberately shows the email everywhere. The user is picked via search — no free-text usernames. - Enforcement is server-side: with
block, an exceeded cap makes chat/training requests fail with HTTP 429 (or a WebSocket error frame) whose body carrieserror_code: "spend_cap_exceeded". Handle it in custom chat UI, or mountSpendCapUsageto warn users before they hit it. - Three scopes: organization (workspace-wide), agent, and per-user-per-
agent — the tightest applicable cap governs. This tab manages the
two agent-level scopes; the workspace-wide limit belongs to the
organization settings Billing surface (
/iblai-vibe-billing, which also lists every agent's cap in one place). - RBAC: each scope's endpoints are gated separately; a 403 renders the denied panel for that sub-tab only.

Spend Caps REST API
For custom UI beyond the tab. All endpoints are prefixed with
${dmUrl}/api/ai-mentor/orgs/{org}/ where dmUrl is
NEXT_PUBLIC_API_BASE_URL. Auth: Authorization: Token <token>.
Use the canonical agents/ spelling — mentors/ is a deprecated
alias.
Agent spend cap (singleton per agent)
| Method | Path | Purpose |
|---|---|---|
| GET | agents/{mentor_unique_id}/spend-cap/ |
Read (404 = no cap configured) |
| PUT | agents/{mentor_unique_id}/spend-cap/ |
Upsert — create or update |
| DELETE | agents/{mentor_unique_id}/spend-cap/ |
Remove the cap |
Upsert body:
{
"interval_type": "day",
"max_cost_usd": "10.00",
"enforcement": "block",
"alert_thresholds": [80, 95],
"enabled": true
}
interval_type: day | week | month | year.
enforcement: block | alert_only. max_cost_usd is a decimal
string. Responses add the read-only counters (current_spend_usd,
remaining_usd, is_exceeded, period_started_at,
last_reconciled_at).
Per-user limits on an agent
| Method | Path | Purpose |
|---|---|---|
| GET | agents/{mentor_unique_id}/spend-caps/users/ |
List this agent's user caps |
| GET | agents/{mentor_unique_id}/spend-caps/users/{username}/ |
Read one (404 = none) |
| PUT | agents/{mentor_unique_id}/spend-caps/users/{username}/ |
Upsert (same body as above) |
| DELETE | agents/{mentor_unique_id}/spend-caps/users/{username}/ |
Remove |
The list may come back as a bare array or a DRF limit/offset envelope depending on deployment — the SDK slice normalizes both.
Organization scope + organization-wide listing
| Method | Path | Purpose |
|---|---|---|
| GET/PUT/DELETE | spend-caps/tenant/ |
Workspace-wide singleton cap |
| GET | spend-caps/agents/ |
Every configured agent cap in the organization (?mentor=<uuid> filter) |
User-safe status
| Method | Path | Purpose |
|---|---|---|
| GET | spend-caps/status/{user_id}/ |
Zones + fill percentages for the caps covering this user (?mentor=<uuid> to include an agent's caps) — never dollar amounts. Non-admins may only read their own |
Enforcement error
A hard-block cap that is exceeded makes chat/training requests fail with HTTP 429 (or a WebSocket error frame):
{
"error_code": "spend_cap_exceeded",
"error": "...",
"message": "...",
"details": { "scope": "agent", "interval_type": "day", "mentor_unique_id": "..." }
}
Match on error_code === "spend_cap_exceeded"
(SPEND_CAP_EXCEEDED_ERROR_CODE) — a genuine provider rate limit
also uses status 429.
