On-chain options market volume + ranked protocols
API · /optionsdex-api
Options DEX API
Live on-chain crypto options trading volume — the decentralized options market where protocols like Derive, Aevo, Premia, Ithaca and Rysk let users trade calls and puts on-chain, powered by the public DeFiLlama options feed, no key, nothing stored. This is distinct from a centralized options exchange order book: it measures the volume actually flowing through on-chain options venues. The overview endpoint returns the whole on-chain options market's volume over the last 24 hours, 7 days and 30 days plus every protocol ranked by what it trades, measured as notional (contract face value, the default) or premium (what option buyers actually paid). The protocol endpoint returns a single protocol's notional and premium volume side by side across 24h / 7d / 30d / all-time. The chain endpoint returns the options volume and top venues for one blockchain. See which on-chain options venue leads and how DeFi options flow shifts. This is the on-chain options-volume cut of DeFi — distinct from the centralized options-chain, spot-DEX, swap-aggregator, fees and perpetual APIs in the catalogue.

L2BEAT Rollup Risk & TVS API
Live Ethereum layer-2 / rollup risk and value-secured data from L2BEAT — no key, nothing stored. L2BEAT's signature is its independent risk framework: every rollup is rated by maturity Stage (Stage 0 / 1 / 2) and assessed across the canonical risk dimensions — sequencer failure, state validation, data availability, exit window and proposer failure — each carrying a good / warning / bad sentiment and a plain-language explanation. This is the rollup-risk and total-value-secured (TVS) view, distinct from the L2 economics/fundamentals and the on-chain per-chain APIs in the catalogue. The projects endpoint lists every tracked L2 with its type (Optimistic Rollup, ZK Rollup, Validium, layer3…), category, host chain, maturity Stage, TVS and 7-day change. The project endpoint returns one rollup in full — the TVS breakdown (native / canonical / external, and ether / stablecoin / btc / other), the Stage, providers, purposes and the complete risk assessment. The risks endpoint returns just the risk rosette for a rollup with a sentiment tally. The summary endpoint aggregates the whole ecosystem — total TVS, project count and the distribution by Stage and by type. More than a hundred rollups tracked, updated live. Project lookup is by slug (arbitrum, base, optimism, zksync-era, scroll, linea, starknet).

Token Approval Security API
Live audit of the token approvals (allowances) a crypto wallet has granted, and the risk of the contracts it has approved to spend its tokens — powered by the public GoPlus Security data, no key, nothing stored. Token approvals are the single most common way wallets get drained: once you approve a contract to move a token, a malicious or compromised spender can take it whenever it likes. This is the allowance-hygiene layer — the data behind tools like revoke.cash. The approvals endpoint lists every token a wallet has approved, who it approved (the spender contract), how much was approved and when, and whether that spender is flagged as malicious, trusted or unverified, together with a risk summary counting the dangerous approvals to revoke. The contract endpoint profiles a single spender contract before you approve it — its name, whether it is open-source, its creator, deploy time and risk tags. The chains endpoint lists the 40-plus supported blockchains. Catch wallet-draining allowances before they cost a user everything. This is the approval / allowance-risk cut — distinct from the token-contract-security, scam-detection and on-chain APIs in the catalogue.

Token Security API
Live smart-contract risk and safety analysis for crypto tokens and wallet addresses — the on-chain due-diligence check to run before you buy a token or interact with an address, powered by the public GoPlus Security data, no key, nothing stored. The token endpoint scans an ERC-20-style contract on any supported chain and returns whether it is a honeypot, its buy and sell tax, whether it is mintable or has a hidden or privileged owner who can pause trading or take back ownership, whether it is open-source or a proxy, and its holder and LP-holder counts. The address endpoint screens a wallet address against twenty risk signals — cybercrime, money laundering, phishing, sanctions, stealing attacks, honeypot-related addresses and more — and reports exactly which, if any, are flagged. The chains endpoint lists the 40+ supported blockchains. Catch scam tokens, honeypots and tainted addresses before they cost you. This is the real-time contract-security and risk-screening cut of crypto — distinct from the historical exploit database, the price and the on-chain APIs in the catalogue.

DEX Aggregators API
Live trading volume routed through DeFi DEX aggregators — Jupiter, 1inch, CowSwap, Paraswap, OKX Swap, KyberSwap and more — powered by the public DeFiLlama aggregators feed, no key, nothing stored. Aggregators don't hold liquidity themselves: they split each trade across many underlying decentralized exchanges to get the best price, so their volume is the single best measure of where real swap flow actually routes. The overview endpoint returns total aggregator volume over the last 24 hours, 7 days and 30 days plus every aggregator ranked by what it routes, with its category and the chains it covers. The aggregator endpoint returns a single aggregator's volume across 24h / 7d / 30d / all-time. The chain endpoint returns aggregator volume and the top routers for one blockchain (Solana, Ethereum, Base). See which router dominates each chain and how swap flow shifts. This is the swap-routing / aggregator-volume cut of DeFi — distinct from the spot-DEX-volume, fees-and-revenue, TVL and exchange-ticker APIs in the catalogue.
