description	Venice billing and usage analytics - GET /billing/balance, GET /billing/usage-history (keyset-paginated per-request ledger, JSON or CSV), GET /billing/usage (deprecated predecessor), and GET /billing/usage-analytics (aggregated by date/model/key). Covers the DIEM/USD/BUNDLED_CREDITS consumption priority and building dashboards. (Beta)

Venice Billing

Four read-only endpoints for account-level billing and analytics. All are under a Beta tag — schema/behavior may change.

Endpoint	Purpose
GET /billing/balance	Current canConsume flag, remaining DIEM & USD, epoch allocation.
GET /billing/usage-history	Per-request ledger with keyset pagination. JSON or CSV. Use this one.
GET /billing/usage	Deprecated offset-paginated ledger. See the warning below.
GET /billing/usage-analytics	Aggregated breakdowns: by date, model, API key.

All require Bearer auth (not x402 — for wallet balances, use venice-x402). GET /billing/balance, GET /billing/usage-history, and GET /billing/usage require an ADMIN key — an INFERENCE key gets 401. GET /billing/usage-analytics works on any authenticated key (scoped to the account behind the key).

GET /billing/usage is deprecated and mostly closed. It is rate limited to 1 request per minute per user, and accounts created on or after 2026-07-07 are rejected outright with 410 Gone. Every response carries Deprecation: @1783555200 and Link: </api/v1/billing/usage-history>; rel="successor-version". Write new integrations against GET /billing/usage-history, which returns the same data with keyset pagination.

Currency / priority

Venice debits from, in order:

1. DIEM — staked credits (reset per epoch).
2. BUNDLED_CREDITS — included in some Pro plans.
3. USD — prepaid fiat balance.
4. (VCU) — deprecated legacy DIEM.

consumptionCurrency on /billing/balance reports the current currency being consumed.

GET /billing/balance

curl https://api.venice.ai/api/v1/billing/balance \
  -H "Authorization: Bearer $VENICE_API_KEY"

{
  "canConsume": true,
  "consumptionCurrency": "DIEM",
  "balances": { "diem": 90.5, "usd": 25 },
  "diemEpochAllocation": 100
}

• canConsume: false means both DIEM and USD buckets are empty on this endpoint — canConsume here is hasPositiveDiemBalance || usdBalance > 0 and does not factor in bundled credits (which are consulted during the actual request in getConsumableBalanceForRequest).
• consumptionCurrency is "DIEM", "USD", or null (when neither applies).
• balances.diem is null if not staking.
• diemEpochAllocation is the ceiling for the current epoch — balances.diem / diemEpochAllocation = remaining fraction.

GET /billing/usage-history

Per-request ledger with keyset (cursor) pagination. This is the supported way to walk billing history.

curl "https://api.venice.ai/api/v1/billing/usage-history?startTimestamp=2026-06-01T00:00:00Z&endTimestamp=2026-07-01T00:00:00Z&pageSize=1000&currency=USD" \
  -H "Authorization: Bearer $VENICE_ADMIN_KEY" \
  -H "Accept: application/json"

Query parameters

A request is either a filtered first page or a bare continuation. Sending cursor alongside any filter is a 400, and so is any unknown parameter — the validator is strict rather than lenient.

Param	Notes
startTimestamp	Inclusive lower bound, ISO 8601 UTC with a Z suffix. First page only.
endTimestamp	Exclusive upper bound, ISO 8601 UTC. Must be later than startTimestamp. Consecutive windows that share a boundary walk the history with no gaps and no overlaps.
currency	USD / DIEM / BUNDLED_CREDITS.
pageSize	10–1000. Default 1000.
cursor	Opaque continuation token from a previous nextCursor. Carries the filters of the walk it continues, so send it alone.

Response (JSON)

{
  "data": [
    {
      "timestamp": "2026-06-15T19:05:10.504Z",
      "sku": "zai-org-glm-5-1-llm-output-mtoken",
      "units": 0.000227,
      "pricePerUnitUsd": 2.8,
      "amount": -0.06356,
      "currency": "DIEM",
      "notes": "API Inference",
      "inferenceDetails": {
        "requestId": "chatcmpl-4007fd29f42b7d3c4107f4345e8d174a",
        "promptTokens": 339,
        "completionTokens": 227,
        "inferenceExecutionTime": 2964
      }
    }
  ],
  "nextCursor" 

Entries come back in ascending timestamp order. nextCursor is null on the last page. Set Accept: text/csv for CSV, in which case Content-Disposition stamps the export time into the filename (each page of a walk downloads under a unique, sort-ordered name) and nextCursor moves to the x-next-cursor response header.

Entry fields match /billing/usage (see below), with inferenceDetails sub-fields nullable when a count or timing was not recorded.

Walking the full history

let url = `${base}/billing/usage-history?startTimestamp=${start}&endTimestamp=${end}`
for (;;) {
  const page = await fetch(url, { headers }).then(r => r.json())
  handle(page.data)
  if (page.nextCursor === null) break
  url = `${base}/billing/usage-history?cursor=${encodeURIComponent(page.nextCursor)}`
}

GET /billing/usage (deprecated)

Offset-paginated per-request ledger. Kept alive for grandfathered accounts only; see the deprecation warning at the top of this skill before using it.

curl "https://api.venice.ai/api/v1/billing/usage?limit=200&page=1&sortOrder=desc&currency=USD&startDate=2026-04-01T00:00:00Z&endDate=2026-04-21T23:59:59Z" \
  -H "Authorization: Bearer $VENICE_API_KEY" \
  -H "Accept: application/json"

Query parameters

Param	Notes
currency	USD / VCU / DIEM / BUNDLED_CREDITS.
startDate / endDate	ISO 8601 datetime.
limit	1–500. Default 200.
page	Default 1.
sortOrder	asc / desc on createdAt. Default desc.

Accept header

• application/json (default) — paginated JSON.
• text/csv — downloads billing-usage.csv (sets Content-Disposition).

Response (JSON)

{
  "warningMessage": "DIEM (formerly VCU) has been renamed...",
  "data": [
    {
      "timestamp": "2026-04-20T12:34:56Z",
      "sku": "zai-org-glm-5-1-llm-output-mtoken",
      "units": 0.000227,

      "amount": -0.06356,
      "currency": "DIEM",
      "notes": "API Inference",
      "inferenceDetails": {
        "requestId": "chatcmpl-...",
        "promptTokens": 339,
        "completionTokens": 227,
        "inferenceExecutionTime": 2964
      }
    
  
            

Response headers: x-pagination-{limit,page,total,total-pages}.

Fields

• sku — billing line item (model + unit type + format).
• units — for LLMs, millions of tokens (e.g. 0.000227 = 227 tokens).
• pricePerUnitUsd — rate; for DIEM, DIEM ≈ USD so this doubles as reference.
• amount — negative for debit.
• inferenceDetails — present for inference SKUs; requestId is the id returned on the original /chat/completions response.

GET /billing/usage-analytics

Aggregated summary for dashboards. Cached 10 minutes.

curl "https://api.venice.ai/api/v1/billing/usage-analytics?lookback=7d" \
  -H "Authorization: Bearer $VENICE_API_KEY"

Query parameters (choose one approach)

• lookback=Nd — 7d, 30d, up to 90d. Default 7d.
• OR startDate=YYYY-MM-DD + endDate=YYYY-MM-DD — both required if either is given.

Response (selected keys)

{
  "lookback": "7d",
  "byDate": [{ "date": "2026-04-20", "USD": 0.5, "DIEM": 10.25 }, ...],
  "byModel": [
    {
      "modelName": "GLM 5.1",
      "unitType": "tokens",
      "modelType": "LLM",
      "totalUsd": 0.4,
      "totalDiem": 12.5,
      "totalUnits": 50000,
      "breakdown": [
        { "type": "Output"       
                  
      
    
  
   
           
  
   ...
    
   
        
            
        
            
  
   ...
   ...
   ...

• byDate / byModelDaily / byKeyDaily are pre-shaped for time-series charts.
• topModels / topKeyNames give top-8 names for legend rendering.
• apiKeyId: null in byKey means the usage originated from Venice's web app.

Recipes

Abort before calling inference if balance is empty

const { canConsume } = await fetch(`${base}/billing/balance`, { headers }).then(r => r.json())
if (!canConsume) throw new Error('Venice balance exhausted — top up before continuing')

Monthly CSV export

curl "https://api.venice.ai/api/v1/billing/usage-history?startTimestamp=2026-04-01T00:00:00Z&endTimestamp=2026-05-01T00:00:00Z&pageSize=1000" \
  -H "Authorization: Bearer $VENICE_ADMIN_KEY" \
  -H "Accept: text/csv" \
  -o billing-april.csv

Read x-next-cursor off the response and re-request with ?cursor=<token> (and no other parameters) until the header is absent.

Top-models chart

const a = await fetch(`${base}/billing/usage-analytics?lookback=30d`, { headers }).then(r => r.json())
// chart(a.byModelDaily, { series: a.topModels, xField: 'date' })

Errors

Code	Meaning
400	Bad params (startDate without endDate, calendar range > 90 days). On /billing/usage-history: a cursor sent with any filter, an unknown parameter, or endTimestamp not later than startTimestamp. lookback=100d is silently clamped to 90 days rather than rejected.
401	Auth failed, or INFERENCE key used on /billing/balance, /billing/usage-history, or /billing/usage (ADMIN required).
410	/billing/usage only — the account was created on or after 2026-07-07 and must use /billing/usage-history.
429	/billing/usage only — the deprecated 1 request/minute cap.
500	Internal error.
504	Analytics query timed out — shorten lookback or date range.

Gotchas

• This is Beta — field names may shift. Validate against swagger.yaml periodically.
• Don't build anything new on /billing/usage. One request per minute is not a pagination budget, and new accounts can't call it at all.
• /billing/usage-history takes startTimestamp / endTimestamp / pageSize; /billing/usage takes startDate / endDate / limit / page. The parameter names do not carry over when you migrate.
• /billing/usage-history accepts USD, DIEM, and BUNDLED_CREDITS for currency. Legacy VCU is only on /billing/usage.
• currency values on /billing/usage include legacy VCU — use DIEM instead in new code.
• inferenceDetails is null for non-inference SKUs (e.g. subscription charges).
• The analytics endpoint is cached 10 min — sudden spikes lag in the dashboard by that window.
• byModelDaily.date is a Unix milliseconds integer; byDate.date is a YYYY-MM-DD string. Don't mix them.
• Usage entries from the Venice web app have apiKeyId: null — don't drop them when reconciling.
• For x402 (wallet) balance, don't use this endpoint — use GET /x402/balance/{walletAddress}.
