# SAM.gov API key A SAM.gov API key is generated in your SAM.gov account under Account Details, and it must be replaced every 90 days. A personal key with no SAM.gov role allows 10 requests a day; a role or a non-federal system account raises that to 1,000. Create a SAM.gov account (it signs in through login.gov). Open your profile, then Account Details.Checked on 2026-11-12.Official source: [SAM.gov Terms of Use](https://sam.gov/about/terms-of-use) | Where | SAM.gov, Account Details, Public API Key | | --- | --- | | Expiry | Every 90 days | | Sharing | Personal keys may not be shared | | Limit without a role | 10 requests a day | | Limit with a role | 1,000 requests a day | ## How do I get a SAM.gov API key? - Create a SAM.gov account (it signs in through login.gov). - Open your profile, then Account Details. - Enter your password under Public API Key and request the key. - Copy the key. SAM.gov asks for your password again whenever you retrieve it. ## Why does my SAM.gov API key stop working? SAM.gov's terms require updating API keys and system account passwords every 90 days. After that the key is rejected and a new one has to be generated. A 429 response means the daily limit was reached, not that the key expired. ## How do I get more than 10 requests a day? Get a role in a SAM.gov entity registration (for example as a user of your own company's registration) or request a non-federal system account. Both raise the limit to 1,000 a day. System accounts also need an IP allowlist. | Who | Key type | Daily limit | | --- | --- | --- | | Non-federal user, no SAM.gov role | Personal | 10 | | Non-federal user with a SAM.gov role | Personal | 1,000 | | Federal user | Personal | 1,000 | | Non-federal system account | System account | 1,000 | | Federal system account | System account | 10,000 | ## A key with no expiry SAM Gov API keys start with sg_, do not expire on a 90-day clock, and can be revoked from the dashboard.
