Zyte API rate limits#

Zyte API limits the number of requests per minute (RPM). Each API key has a rate limit that can be increased. Additional rate limits may apply.

Rate-limited requests receive a rate-limiting response at no cost and can be retried.

API key rate limit#

Enterprise plans: Custom
Standard plans: 500 RPM

To increase your rate limit, see Increasing rate limits.

Other rate limits#

Additional rate limits may apply:

  • Website limits: Each website has its own rate limit to prevent issues on target sites.

  • Account-website limits: Each account has per-website limits to ensure fair access.

  • Temporary limits: Applied during high demand to ensure platform stability.

Increasing rate limits#

Temporary increases

  • Target API key

  • Desired RPM

  • Target websites

  • Start and end dates

Permanent increases

Standard plans: Contact sales to upgrade to an Enterprise plan
Enterprise plan: Contact your account manager

Concurrency#

Rate limits are based on requests per minute, not concurrent requests.

Your maximum concurrency depends on:

Estimation formula:

max concurrency ≈ RPM limit ÷ 60 × avg response time (seconds)
