Is this address sanctioned? Screens a crypto address against the US Treasury OFAC SDN list's published digital currency addresses (ETH, USDC, USDT, XBT, SOL, TRX and others): the listed entity, programs and listing date on a match, or not found as of the list date. Adds whether it is a wallet (EOA) or contract on Base, Ethereum, Arbitrum, Optimism or Polygon, or a wallet or program-derived address

Re-check up to 5 tokens you hold or watch in one call, on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana: each token's 0-100 risk score, level, reason codes, price, liquidity and a fingerprint. Send the fingerprints back as since to get what changed (new risks, owner or authority changes, liquidity or price moves of 10%+) and a short list of alerts. One price for the whole list, made for po

Live DEX price, 24h change, volume, liquidity and market cap for up to 30 tokens per call on ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, solana.

NFT metadata for ERC-721 and ERC-1155 tokens on Base, Polygon, Arbitrum, Optimism and Ethereum. Resolves tokenURI through IPFS, Arweave, data: URIs and public HTTPS, and returns the parsed metadata JSON.

GLB optimizer: Inspect a GLB without changing it: triangles, draw calls, materials, texture memory, animations, glTF validator errors, and concrete suggestions to make it lighter. Full schema: https://rengi.dev/v1/glb-optimizer/schema

Smart contract security scan for AI agents: give a chain id and contract address, get Slither static-analysis findings (reentrancy, unchecked calls, arbitrary sends, etc.), proxy/upgradeability status and the list of owner/role-gated admin functions (mint, pause, blacklist, upgrade). Works on any Sourcify-verified contract on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB. Use before approving,

Real-time L2 sequencer health across 12 chains (Base, Arbitrum, Optimism, zkSync, Blast, Linea, Mantle, Mode, Scroll, Taiko, Polygon zkEVM, Casper). Returns kernel-level P99/P95 RTT from eBPF probes, revert ratios (Base and Arbitrum via eth_getBlockReceipts), gas pressure, and execution recommendation.

[MCP: optimize_context] Pay-per-call JSON context pruning & LLM token budget enforcement. Saves up to 85% prompt tokens.

Premium machine-readable x402 commerce intelligence bundle: catalog snapshot, median pricing signals, earning playbooks, and ecosystem JSON for agents optimizing marketplace presence.

Call any view/pure function with a human-readable signature on Ethereum, Base, Arbitrum, Optimism, Polygon or BSC: decoded result, raw hex, block number, chain id; 422 with revert reason on revert.

Recent transaction history for an address, normalized across Ethereum, Base, Arbitrum, Optimism, Polygon, Bitcoin, and Solana -- direction, counterparty, and value where the chain's data model makes that derivable.

Read-only EVM state API for wallet snapshots, ERC-20 balances, token allowances, contract code, block heights, and bounded eth_call reads across Ethereum, Base, Arbitrum, Optimism, and Polygon. Fixed price: $0.15 USDC on Base for a batch of up to 100 checks. Only submitted checks run. Results are provider-reported RPC data, not cryptographic proofs.

Base yield API / best APY on Base / DeFi yield aggregator / stablecoin yield finder / lending APY / LP yield. Quality-filtered live yields across Base lending markets (Morpho, Moonwell — no impermanent-loss risk) and DEX LP pools, with a best-per-asset recommendation and per-pool risk scoring. For AI agents, yield optimizers, and treasury bots allocating capital on Base.

Checks whether a signature was made by a claimed EVM address: EIP-191 personal_sign messages, EIP-712 typed data or a raw 32-byte digest, verified by ecrecover for wallets or ERC-1271 isValidSignature for smart-contract wallets (Safe, Coinbase Smart Wallet) on Ethereum, Base, Arbitrum, Optimism or Polygon.

Pass ?chain

Checks one address on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain against the open verification registry and against the chain itself. For a proxy the answer is deliberately split in two: whether the proxy is verified says almost nothing, whether the implementation it currently points to is verified is the real question, and both are reported separately with the implementation a

Current USD price, market cap, 24h volume and 24h change for up to 10 cryptocurrencies by ticker symbol (BTC, ETH, SOL, ...) or for any on-chain token by contract address and chain (ethereum, base, bsc, arbitrum, polygon, optimism, avalanche, solana). Data from CoinGecko.

Concentrated LP Range Optimizer analyses only the evidence supplied by the caller. It does not claim to query a chain, identify a legal status or replace an independent audit. Missing signals lower confidence and are listed explicitly; every classification includes the exact thresholds used.
