Gas prices play a crucial role in the speed and cost of executing transactions on a blockchain, and fluctuate frequently based on network demand and usage. By using this endpoint, developers can stay up-to-date with the latest gas prices and adjust their application's transaction parameters accordingly to ensure optimal speed and cost efficiency. ## OpenAPI ````yaml /openapi-v1.yaml get /v1/gas-prices/ openapi: 3.0.3 info: version: 1.0.0 title: REST API description: REST-like API provides access to rich Zerion ecosystem. contact: name: Zerion API url: https://developers.zerion.io/ email: api@zerion.io servers: - description: Production API url: https://api.zerion.io security: - APIKeyBasicAuth: [] tags: - name: wallets description: >- Operations related to wallets, such as portfolio charts, positions, and transactions. - name: wallet sets description: >- Operations on a wallet set — aggregated portfolio data across at most one EVM address and one Solana address queried together. - name: fungibles description: >- Operations related to fungible assets, such as list them all, search or get by ID. - name: chains description: Operations related to chains, such as list all chains. - name: swap description: Operations related to swapping and bridging assets. - name: gas description: Operations related to gas. - name: nfts description: >- Operations related to non fungible assets, such list them, search or get by ID. - name: dapps description: >- Operations related to decentralized applications, such as list them all, search or get by ID. - name: subscriptions to transactions description: Operations related to subscriptions to transactions. paths: /v1/gas-prices/: get: tags: - gas summary: Get list of all available gas prices description: >- This endpoint provides real-time information on the current gas prices across all supported blockchain networks.
