Features are reusable capabilities that can be attached to several plans with different limits and prices.

Feature types

Type	Use it for
`boolean`	On/off capabilities such as SSO
`usage`	Metered quantities such as API calls
`seats`	Per-user licenses
`quota`	Durable integer balances that can rise and fall

The feature code is the identifier used by Feature Access, Usage, Seats, and Quota. Use lowercase letters, numbers, and underscores.

Current feature state

Use featureAccess.get to read whether the customer currently has access and the feature's current counters:

import { Commet } from "@commet/node";const commet = new Commet({ apiKey: "ck_xxx" });const featureAccess = await commet.featureAccess.get({  code: "api_calls",  customerId: "user_123",});

from commet import Commetcommet = Commet("ck_xxx")feature_access = commet.feature_access.get(    "api_calls",    customer_id="user_123",)

client, err := commet.New("ck_xxx")if err != nil {	log.Fatal(err)}ctx := context.Background()featureAccess, err := client.FeatureAccess.Get(ctx, "api_calls", &commet.GetFeatureAccessParams{	CustomerID: "user_123",})if err != nil {	log.Fatal(err)}

import co.commet.Commet;import co.commet.params.GetFeatureAccessParams;var commet = Commet.builder().apiKey("ck_xxx").build();var featureAccess = commet.featureAccess().get(    "api_calls",    GetFeatureAccessParams.builder("user_123").build());

use Commet\Commet;$commet = new Commet('ck_xxx');$featureAccess = $commet->featureAccess->get(    code: 'api_calls',    customerId: 'user_123',);

The exact response is discriminated by feature type. It can include enabled state, usage, included units, remaining units, seats, or quota values.

Use the list operation to retrieve the customer's complete current feature state:

import { Commet } from "@commet/node";const commet = new Commet({ apiKey: "ck_xxx" });const response = await commet.featureAccess.list({ customerId: "user_123" });

from commet import Commetcommet = Commet("ck_xxx")feature_access_list_result = commet.feature_access.list(customer_id="user_123")

client, err := commet.New("ck_xxx")if err != nil {	log.Fatal(err)}ctx := context.Background()featureAccessListResult, err := client.FeatureAccess.List(ctx, &commet.ListFeatureAccessParams{	CustomerID: "user_123",})if err != nil {	log.Fatal(err)}

import co.commet.Commet;import co.commet.params.ListFeatureAccessParams;var commet = Commet.builder().apiKey("ck_xxx").build();var featureAccessListResult = commet.featureAccess().list(    ListFeatureAccessParams.builder("user_123").build());

use Commet\Commet;$commet = new Commet('ck_xxx');$featureAccessListResult = $commet->featureAccess->list(customerId: 'user_123');

Feature Access lists return the standard { object, data, hasMore, nextCursor } envelope.

Prospective consumption

Use usage.check before an action when you need to know whether a specific quantity can be consumed and what it would cost:

import { Commet } from "@commet/node";const commet = new Commet({ apiKey: "ck_xxx" });const usageCheck = await commet.usage.check({  customerId: "user_123",  featureCode: "api_calls",});

from commet import Commetcommet = Commet("ck_xxx")usage_check = commet.usage.check(    customer_id="user_123",    feature_code="api_calls",)

client, err := commet.New("ck_xxx")if err != nil {	log.Fatal(err)}ctx := context.Background()usageCheck, err := client.Usage.Check(ctx, &commet.CheckUsageAvailabilityParams{	CustomerID: "user_123",	FeatureCode: "api_calls",})if err != nil {	log.Fatal(err)}

import co.commet.Commet;import co.commet.params.CheckUsageAvailabilityParams;var commet = Commet.builder().apiKey("ck_xxx").build();var usageCheck = commet.usage().check(    CheckUsageAvailabilityParams.builder("user_123", "api_calls").build());

use Commet\Commet;$commet = new Commet('ck_xxx');$usageCheck = $commet->usage->check(    customerId: 'user_123',    featureCode: 'api_calls',);

The response is discriminated by the plan's consumption model:

metered reports current, remaining, included, and overage pricing.
credits reports the estimated credit cost and available pools.
balance reports the estimated monetary amount and current balance.

Do not use Feature Access as a substitute for this prospective check. Feature Access describes current state; Usage Check evaluates the proposed consumption.

Track the consumption

Once the action succeeds, record it through Usage:

import { Commet } from "@commet/node";const commet = new Commet({ apiKey: "ck_xxx" });const usageEvent = await commet.usage.track({  featureCode: "api_calls",  customerId: "user_123",  model: "example",  inputTokens: 1,  outputTokens: 1,});

from commet import Commetcommet = Commet("ck_xxx")usage_event = commet.usage.track(    feature_code="api_calls",    customer_id="user_123",    model="example",    input_tokens=1,    output_tokens=1,)

client, err := commet.New("ck_xxx")if err != nil {	log.Fatal(err)}ctx := context.Background()usageEvent, err := client.Usage.Track(ctx, &commet.TrackUsageParams{	FeatureCode: "api_calls",	CustomerID: "user_123",	Model: func(value string) *string { return &value }("example"),	InputTokens: func(value int) *int { return &value }(1),	OutputTokens: func(value int) *int { return &value }(1),})if err != nil {	log.Fatal(err)}

import co.commet.Commet;import co.commet.params.TrackUsageParams;var commet = Commet.builder().apiKey("ck_xxx").build();var usageEvent = commet.usage().track(    TrackUsageParams.builder("api_calls", "user_123").model("example").inputTokens(1L).outputTokens(1L).build());

use Commet\Commet;$commet = new Commet('ck_xxx');$usageEvent = $commet->usage->track(    featureCode: 'api_calls',    customerId: 'user_123',    model: 'example',    inputTokens: 1,    outputTokens: 1,);

Use the caller-owned eventId for the business event when retries must deduplicate it. Request idempotency is a separate transport option that maps to Idempotency-Key.
