The response includes the number of validators in each queue, the total effective balance in gwei for each queue, and the total validator count known to the explorer. No parameters are required. ## OpenAPI ````yaml /api/v1/bundled.yaml get /api/v1/validators/queue openapi: 3.0.4 info: title: beaconcha.in API Documentation license: name: GPL-3.0 url: https://www.gnu.org/licenses/gpl-3.0.en.html description: >- > ⚠️ No new features or endpoints will be added to V1. We recommend the [V2 API](/api/overview) for all new projects. See the [migration guide](/api/v1-to-v2-migration). ## Introduction **Advanced and reliable API for accessing comprehensive Ethereum blockchain data.** - **Free Usage Policy:** The API is free to use under a fair use policy, with rate limits of 10 requests per minute per IP. - **Caching:** All responses are cached for 1 minute. - **Higher Usage Plans:** For higher usage plans, visit: [https://beaconcha.in/pricing](https://beaconcha.in/pricing). An API key is required to use these plans. ### API Key Usage API keys can be obtained at [/user/settings](https://beaconcha.in/user/settings) and must be included in requests either as a query string parameter or in the request header. #### Example: Query String Parameter ```bash curl https://beaconcha.in/api/v1/slot/1?apikey= ``` #### Example: Request Header ```bash curl -H 'apikey: ' https://beaconcha.in/api/v1/slot/1 ``` contact: {} version: '1.1' servers: - url: https://beaconcha.in description: Ethereum mainnet - url: https://hoodi.beaconcha.in description: Hoodi Ethereum testnet security: - ApiKeyAuthQuery: [] - ApiKeyAuthHeader: [] tags: - name: Epoch description: Data related to consensus layer epochs - name: Slots description: Data related to consensus layer slots - name: Validators description: Data related to consensus layer validators - name: Rewards description: Data related to validator rewards - name: Sync Committees description: Data related to sync committees - name: Rocketpool description: Data related to the rocketpool protocol - name: ETH.Store® description: Data related to the ETH.Store® metric - name: Validator deposits description: Data related to execution layer validator deposits - name: Blocks description: Data related to execution layer blocks - name: Gas description: Data related to gas prices - name: Address description: Data related to ethereum addresses - name: Network description: Network data - name: Misc description: Miscellaneous data - name: User description: User data - name: Machine Metrics description: Submit machine, beacon-node, and validator-client monitoring metrics paths: /api/v1/validators/queue: get: tags: - Validators summary: Validator activation and exit queue description: >- Retrieve current queue metrics for validators awaiting activation (entering) and validators scheduled to exit (exiting).
