Token Security API

healthy 4,892 Subscribers

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.

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).

Independent Reserve Exchange API

Live order-book exchange data from Independent Reserve, the regulated Australian / New Zealand crypto venue, over its public API — no key, nothing stored. This is the regional venue view for the AUD, USD, NZD and SGD order books: Australasian and Singapore on-exchange price discovery, distinct from the global-aggregate and the other regional-exchange APIs in the catalogue. The ticker endpoint returns a pair market summary — last traded price, 24h high/low, day volume, the live best bid and offer and the implied spread. The orderbook endpoint returns the live limit-order book — top bids and asks with cumulative depth and the bid/ask spread — so you can read on-venue liquidity. The trades endpoint returns the most recent executed trades. The history endpoint returns the hourly trade-history summary for the last N hours (per-hour open/high/low/close, volume and trade count). The markets endpoint lists every supported coin and the four fiat quote currencies. Forty-one cryptos (BTC, ETH, SOL, XRP and more) quoted against AUD, USD, NZD and SGD, updated live. Currency codes are case-insensitive and BTC is accepted either as btc or its upstream code xbt.

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.

RedStone Oracle Prices API

Live oracle price feeds for over a thousand assets across every asset class in a single source — cryptocurrencies, US equities and ETFs, precious metals and commodities, fiat currencies and liquid-staking and real-world-asset tokens — served from the public RedStone oracle, no key, nothing stored. RedStone is the decentralized oracle that DeFi protocols read on-chain for their prices, so this is the cross-asset reference-price layer: the same feed gives you Bitcoin, Apple, gold, the euro and wstETH side by side, each stamped with the time the oracle signed it. The price endpoint returns one asset's latest oracle value. The prices endpoint returns many assets in one call — mix crypto, stocks, metals, FX and staking tokens freely. The symbols endpoint lists and searches every supported asset, from majors to obscure liquid-staking and tokenized real-world assets you will not find in a normal price feed. This is the multi-asset oracle-price cut — one feed for every class — distinct from the single-asset-class price, converter and precious-metals APIs in the catalogue.
