We offer a fair use base rate limit of 500,000 requests per month, with 200 requests per 5 minutes per IP address, which is designed to cover most small to medium applications. The rate limit should allow for roughly 30 search-sessions in a 5-minute period and is intended to discourage abuse. Use a debounce strategy inbetween keystrokes to avoid hitting the rate limit.If your usage approaches the monthly limit, we may reach out to discuss an upgrade to a paid, unlimited tier.For enterprises, we provide custom solutions, including SLA agreements, custom terms, and flexible caching options to ensure optimal performance at scale. These plans are tailored to meet the needs of high-volume users.Feel free to contact us to discuss the right plan for your use case.
