    "description": "The Apollo API provides programmatic access to [Apollo](https://www.apollo.io/), the all-in-one sales intelligence and engagement platform. Use it to enrich people and company data (individually or in bulk), search Apollo's database of over 240 million contacts and 30 million companies, and manage accounts, contacts, deals, sequences, tasks, calls, and conversations in your go-to-market workflows.\n\n## Base URL\n\nAll API requests are made to `https://api.apollo.io/api/v1`.\n\n## Authentication\n\n- **Apollo users** authenticate with an API key passed in the `x-api-key` request header. See [Create API Keys](https://docs.apollo.io/docs/create-api-key).\n- **Apollo partners** building integrations on behalf of mutual users authenticate with the [OAuth 2.0 authorization flow](https://docs.apollo.io/docs/use-oauth-20-authorization-flow-to-access-apollo-user-information-partners).\n\n## Rate limits & credits\n\nRate limits and credit consumption depend on your [Apollo pricing plan](https://docs.apollo.io/docs/api-pricing). Check your current limits and usage with the [view API usage stats and rate limits](https://docs.apollo.io/reference/view-api-usage-stats) endpoint. For more details, see [Rate Limits](https://docs.apollo.io/reference/rate-limits) and the [API FAQs](https://docs.apollo.io/docs/apollo-api-faqs).\n\nNew to the API?
