Sequence Hq Rate Limits

Sequence publishes per-API-key rate limits on its REST API. Standard endpoints are limited to 1,500 requests per minute per API key. The high-volume usage ingestion endpoint (POST /api/usage-events) has a separate, much higher ceiling of 12,000 requests per minute per API key, reflecting its role as the metering hot path for usage-based billing. Requests over the limit are throttled with an HTTP 429 response.

Sequence Hq Rate Limits is the machine-readable rate-limit profile for Sequence on the APIs.io network, in the API Commons Rate Limits shape.

It captures 2 rate-limit definitions, measuring requests.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Billing, Usage-Based Billing, Metering, Rate Limiting, and Quotas.

Policies

Per-Key Limits
Limits are enforced per API key (Client ID / Client Secret pair), so throughput can be scaled by provisioning additional keys where permitted.
Backoff Strategy
Clients should implement exponential backoff with jitter on HTTP 429 responses and honor any Retry-After header.
Idempotency
Usage events accept a customerEventId idempotency key so safe retries after throttling do not double-count usage.
