Submittable Rate Limits

Submittable publishes explicit throttling for its API: roughly 10 transactions per second and 10,000 transactions per hour. These are the two documented constraints on API usage. List endpoints in v4 page with continuation tokens rather than page numbers, which shapes how many transactions a full data pull consumes. Clients that exceed the limits should expect throttling and back off.

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

It captures 2 rate-limit definitions, measuring transactions.

An exhausted limit returns HTTP 429.

Policies

Pagination
v4 list endpoints return a continuation token; fetch subsequent pages by passing it back, which spreads a full export across multiple transactions.
Backoff Strategy
On throttling, implement exponential backoff with jitter and stay within the 10/sec and 10,000/hour ceilings.
