Scans the whole perpetual market and ranks the most crowded longs and shorts by funding, so an agent finds squeeze / mean-reversion setups in one call. Extreme positive funding = crowded long (long-squeeze risk on a dip); extreme negative = crowded short (short-squeeze fuel on a pump). Returns the market tilt plus the top coins at each edge, OI-weighted over a liquidity floor. CoinGecko, no key. A setup radar, not an entry signal. Not financial advice.

Give a Base transaction hash and AI explains what it actually did in plain English — the action, a risk read (failed tx, risky approval, high-value transfer), and notes. Turns raw calldata into an answer agents and humans can use.

🆕 B20 Stablecoin tokens self-declare a fiat currency code (currency() → USD, EUR, …). Reads that declared peg alongside the issuance profile (supply, cap) and control powers (seize/freeze/pause/uncapped-mint) — a one-call 'what is this stablecoin and who controls it' for agents settling in B20 stablecoins. The currency code is the issuer's claim, not attested backing.

Checks whether a specific wallet is authorized under a B20 token's transfer-sender policy. If it isn't, that wallet can't transfer and can be burnBlocked() (SEIZED) by the issuer. The personal companion to b20-safety — 'can this token freeze MY funds?'

The live layer over B20 Policy Watch: a network-wide onchain webhook captures every B20 PolicyUpdated/Paused sub-second. Pass a token address for its live guard status, or call with no address for the feed of tokens that JUST attached a sender blocklist (turned seizable) across all of Base.

🆕 B20 Asset tokens can post on-chain announcements (Announcement: id, description, uri) — issuer notices, corporate actions, redemptions — a channel ERC-20 has no equivalent for. Reads a token's announcement feed (active vs ended) from CDP-indexed events. The issuer-communications primitive for agents holding tokenized/RWA B20 assets.

Combines security flags with the verified ABI's function names, then AI explains the contract's dangerous capabilities — owner can mint, pause, blacklist, upgrade or self-destruct — with a danger level. Goes beyond raw flags to read what the contract can actually do.

Measured APY of NEAR liquid staking (LiNEAR, Meta Pool stNEAR): each token's redemption price in NEAR now against N days ago from an archival node, annualised — no advertised rates. Plus NEAR staked behind each, and the cost of exiting instantly by selling for wNEAR through NEAR Intents instead of waiting ~2–3 days to unstake. days sets the window (default 7), size the exit in USD.

Price change and trading volume across 1h, 6h and 24h windows for a Base token, plus a trend read (strong_up → strong_down). Lets agents gauge momentum, not just a single 24h number.

Registration age, expiry and registry status for any domain, from RDAP — the registries' own protocol. Returns days since registration, days to expiry, registrar, EPP status codes, nameservers and DNSSEC as one GO / HOLD / STOP verdict. Domain age is the strongest cheap signal in invoice and vendor-impersonation fraud: the payment details that change always arrive from a domain registered weeks ago. Refuses rather than guessing when a registry publishes no RDAP.

Lists every DEX pool for a Base token (pair address, DEX, quote symbol, price, liquidity, 24h volume), sorted by liquidity. Tells agents where — and how deep — a token can be traded.

A token on several Base DEXes should cost about the same on each; a gap is either an arbitrage window or, on a thin pool, a mispricing that signals wash/manipulation. Compares the price across the LIQUID venues (over a floor, default $5k): tight (trustworthy), arb_window, wide (likely mispricing), or single_venue (one pool, as manipulable as it is thin). Separates real arbitrage from thin-pool noise. Snapshots — confirm with a live quote. Not financial advice.

Top DeFi protocols ranked by total value locked (DefiLlama), with 1d/7d change — CEX/Chain/Bridge excluded so this is real DeFi. Pass chain= (e.g. base) to filter to protocols active on it, category= (e.g. Lending, Dexes) to narrow, limit= up to 50. tvlUsd is the protocol's GLOBAL TVL; chain filters presence, not per-chain TVL. The DeFi-rankings commodity, served cheap. Not financial advice.

The crypto Fear & Greed Index (alternative.me): 0 = extreme fear, 100 = extreme greed, from volatility, momentum, volume, social and dominance — plus the day-over-day change and recent history. The one-number market-mood read an agent uses to size risk. Pass days= for history (up to 30). A sentiment gauge, not a signal. Not financial advice.

Unlimited allowances are the #1 drain vector, and agents reach for approve(max) on every swap. This builds ready-to-sign calldata for an approval of EXACTLY the amount you need (via the token's decimals) and refuses unlimited unless forced. Reads the live allowance and returns a revoke step first when one is already set (a non-zero→non-zero approve reverts on USDT-style tokens). Build-time prevention, not detection; we never hold keys. Not financial advice.

Current floor price for a Base NFT collection (OpenSea / LooksRare) via Alchemy. Pass the collection contract address. Coverage is limited to marketplace-listed collections. For agents tracking NFT markets.

Get the list of Twitter/X users who reposted a specific tweet. Returns paginated user profiles for a given tweet ID. Query params: id (string, required) - numeric tweet ID; next_token (string, optional) - pagination cursor, e.g. GET /tweets/retweeted_by?id=1110302988. Returns X v2 API-compatible JSON.

Every pre-funded agent wallet carries idle USDC that earns nothing. This reads the live USDC supply rate across Base money markets (Aave v3, Moonwell) straight from each protocol — not a feed — and returns the best, with the annual yield on your balance so you can weigh moving against the gas. Rates are variable and change every block; a venue it could not read is excluded from 'best', never sent funds on an unconfirmed rate. Pass amount= for the yield projection. Not financial advice.

Compute keccak256 (the EVM/Solidity hash — event topics, function selectors, mapping keys) or sha256 of any input. Pass input=text for UTF-8, or 0x-hex to hash raw bytes; algo=keccak256 (default) or sha256. Returns the digest and, for keccak, the 4-byte function selector. Pure compute, no chain, sub-cent — the commodity hashing call the whole x402 ecosystem hammers, served at the floor. Not financial advice.

Total stablecoin market capitalisation and the largest stablecoins by circulating supply across all chains (DefiLlama), with peg type/mechanism and live price — plus a depeg watch flagging any USD-pegged coin 2%+ off a dollar. The stablecoin-market commodity agents track; for a single Base-stablecoin peg check use stablecoin-peg. Not financial advice.
