Semantic Scholar Rate Limits
The Semantic Scholar API enforces rate limits at both the unauthenticated (shared pool) and authenticated (per-key) levels. Exceeding any limit returns HTTP 429 Too Many Requests. The documentation recommends implementing exponential backoff strategies for all callers.
Semantic Scholar Rate Limits is the machine-readable rate-limit profile for Semantic Scholar on the APIs.io network, conforming to the API Commons Rate Limits specification.
It captures 3 rate-limit definitions, measuring requests and requests_per_second.
Tagged areas include Academic, Research, Papers, Citations, and Authors.

Limits
unauthenticated
100
Shared pool across all unauthenticated users. Effective throughput will be lower during peak usage periods.
authenticated-api-key
1
Introductory dedicated rate of 1 RPS across all API endpoints (Academic Graph, Recommendations, Datasets). Higher limits may be granted after submitting a use-case review request to the Semantic Scholar team.
datasets-api
Bulk dataset downloads are gated behind API key authentication. No published per-second rate limit; exponential backoff is still recommended for large batch jobs.

Every rate limit here is available over the APIs.io API and to AI agents over MCP.
