Seismic Rate Limits

Seismic enforces tiered rate limits per tenant on a 60-second rolling window. Limits are scoped to the tenant (not the API key), and exceeding them returns HTTP 429 with a structured JSON body. Customers needing higher thresholds must request an exemption from Seismic support. Strict enforcement began February 27, 2023.

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

It captures 4 rate-limit definitions, measuring requests_per_minute.

Limit state is signalled in the remaining, total, and retry_after response headers, and an exhausted limit returns HTTP 429.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Sales Enablement, Content Management, and Rate Limiting.

Policies

60-second rolling window
Limits are evaluated against a 60-second rolling window per tenant; the X-Seismic-Total-Calls and X-Seismic-Remaining-Calls headers report current state.
429 response body
When throttled, Seismic returns a JSON body with statusCode, message ("Try again in N seconds"), clientId, and tenant. Use the message to size backoff.
Backoff
Apply exponential backoff with jitter, honoring the seconds-to-retry value in the 429 message body.
Exemption process
Higher-volume tenants can request temporary or permanent exemptions through Seismic support with a documented use case.
No Retry-After header
Seismic returns no Retry-After on 429. The number of seconds to wait is embedded in the prose message body ("Rate limit is exceeded. Try again in N seconds"), so a client must parse a sentence to size its backoff.
