Lithic · Rate Limits

Lithic Com Rate Limits

Lithic publishes fixed numeric requests-per-second (RPS) limits, enforced separately per resource and per HTTP method (a GET and a POST to the same resource draw from independent counters, but multiple GET routes under the same resource, e.g. GET /cards and GET /cards/{token}, share one counter). Defaults differ between Production and Sandbox, with the cards and transfers resources called out as documented exceptions to the default.

Lithic Com Rate Limits is the machine-readable rate-limit profile for Lithic on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 13 rate-limit definitions, measuring requests.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Card Issuing, Fintech, Rate Limiting, and Quotas.

Policies

Per-Resource, Per-Method Enforcement
Limits are tracked independently for each resource and HTTP method; multiple routes under the same resource and method share one counter.
429 Response Headers
A throttled request returns HTTP 429 with an x-requests-remaining header (RPS quota left in the current second) and a retry-after header (seconds to wait).
SDK Auto-Retry
Official Lithic SDKs natively honor the retry-after header and retry throttled requests automatically.
Temporary Reductions
Lithic reserves the right to temporarily lower limits during high load or service incidents, independent of the published defaults.
