Cross-chain messaging and bridging activity across the Wormhole network — one of crypto's largest interoperability protocols, carrying messages and bridged value between 30+ blockchains (Ethereum, Solana, the major L2s, BNB Chain, Sui, Aptos and more) — live from the public Wormholescan API, no key. Over its life Wormhole has relayed well over a billion messages; cross-chain volume is a core health metric of the multi-chain economy: how much value is actually moving between ecosystems, which chains are the busiest source of that flow, and which assets are being bridged. The stats endpoint is the global scorecard: total messages ever relayed, total bridged volume and the value locked, plus message counts and volume over the last 24 hours, 7, 30, 90 days and a year. The chains endpoint ranks the blockchains by their cross-chain transfer activity over the last day — the number of transfers leaving each chain and the dollar volume — so you can see which ecosystems are the busiest exporters of value. The assets endpoint ranks the tokens being bridged the most by dollar volume. This is the cross-chain messaging / bridge-flow cut — distinct from single-bridge feeds (Across, THORChain), the DeFi-TVL and DEX feeds, and the on-chain and price feeds. Volumes and value locked are in US dollars; everything is live. Built for crypto cross-chain analytics, bridge monitoring and multi-chain dashboards.

Live crypto token prices by contract address — no key, nothing cached. Unlike price APIs keyed on a coin slug, this prices a token by its on-chain contract address on its chain, exactly what you have when a token comes out of a wallet, a DEX pair or a transaction. The price endpoint returns the current USD price, symbol, decimals, a confidence score and the timestamp for one or many tokens at once, addressed as chain:address (ethereum:0xA0b8…, a Solana mint, etc.) or as coingecko:slug — USD Coin resolves to about $1.00 and Wrapped Ether to its live price, in one batched call. The historical endpoint returns a token's price at any past moment by Unix timestamp. The chart endpoint returns a price series over a span and period, so you can plot or back-test. It spans every chain DefiLlama indexes — Ethereum, Solana, BSC, Base, Arbitrum and dozens more — including long-tail tokens a slug-based API will not have. This is the address-based price layer every wallet, portfolio tracker, DEX tool and crypto-accounting app needs to value arbitrary tokens. Live from DefiLlama, nothing stored. Distinct from coin-slug price and market-cap APIs — this prices tokens by contract address, across chains. 4 endpoints.
