Ava Labs

Ava Labs is the company behind Avalanche, a high-throughput, low-latency smart-contract blockchain platform. Through AvaCloud it ships a public developer surface for building on Avalanche and its L1s (subnets): a Data API (glacier-api.avax.network) for balances, tokens, transactions, blocks, NFTs and Interchain Messaging; a Metrics API for chain performance and staking analytics; a Webhooks API for real-time address-activity events; and standard JSON-RPC access to the Primary Network's P-Chain, X-Chain and C-Chain. First-party SDKs (AvaCloud SDK for TypeScript, AvalancheJS, AvalancheGo in Go) and the Avalanche-CLI round out the toolchain. This profile was enriched from Ava Labs' published OpenAPI specs and docs.

Ava Labs publishes 3 APIs on the APIs.io network: AvaCloud Data API, AvaCloud Metrics API, and Avalanche Platform Chain API. Tagged areas include Company, Crypto, Blockchain, Avalanche, and Web3.

The Ava Labs catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Ava Labs’ developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, changelog, CLI, and 22 more developer resources.
