Price alert check: whether an asset moved past your threshold from a reference price

Inspect live bytecode and common EIP-1967 and EIP-1167 storage patterns to identify upgradeable contract proxy evidence.

Read recent large ERC-20 transfers directly from Base, Ethereum, or Arbitrum by scanning Transfer logs over the most recent blocks and filtering by a minimum token amount. Defaults to USDC on Base. Public RPC providers cap the scan window, so this covers the most recent blocks rather than a long history, and it does not label exchange wallets.

SYNTHORA resolution-source-feed: give a Polymarket market slug, get its official resolution source READ LIVE — current value, threshold, distance and on-track/off-track verdict. Covers IMF PortWatch chokepoint markets (Hormuz weekly series, normalization binaries): the answer a trader checks before every weekly resolution. Composes gamma-api rules parsing + live official source. $0.05 USDC x402 Base.

binance_crypto_24h_stats intelligence for autonomous agents. Signed x402 call. 0.03 USDC on Base.

Verified smart contract metadata on Base mainnet by address. Returns contract name, compiler version, ABI, implementation address for proxies, license, optimization runs, EVM version. AI agent contract verification, security audit, ABI lookup, Base L2 contract API.

Run a crypto risk report and token security audit that combines current contract-risk signals, live on-chain metadata, deployed bytecode, upgradeable-proxy detection, gas, and optional liquidity evidence. An address with no bytecode is a critical finding, and proxy_detected: false does not prove immutability.

Latest cached signal for one asset (?asset=BTC). Instant.
