Look up the Autonomous System (ASN), prefix, country, registry, and allocation date for an IPv4 address — or for a hostname (which is resolved first). Uses Team Cymru's free DNS-based IP→ASN mapping; no HTTPS upstream, no auth, no rate-limit headaches.

Mask emails, phone numbers, credit-card-like numbers, IPs, and SSNs in text. Returns the redacted text and counts by type.

Validate a JSON document against a JSON Schema (draft-07 subset) and get the list of violations. Supports type, required, properties, items, enum, const, min/max, length, pattern, format, anyOf/allOf/oneOf/not, additionalProperties. Deterministic — check an agent's structured output before you trust it.

Verify an HS256/384/512 JWT signature against a secret and check expiry. Returns valid + decoded payload. (HMAC algorithms only.)

Build the EIP-3009 transferWithAuthorization typed data for a gasless USDC transfer on Base/Polygon/Arbitrum/Optimism/Ethereum — the exact EIP-712 object an agent signs with its OWN key to authorize an x402 payment. We construct it; we never sign or send. Non-custodial.

Resolve an ENS name (e.g. vitalik.eth) to its Ethereum address — so an agent can turn a human-readable recipient into a payable address. Read-only on Ethereum mainnet. ?name=vitalik.eth

Share your namespace with another wallet so different agents can coordinate through it. Grant read or readwrite access to a grantee wallet, optionally with a TTL. This is the cross-agent sharing a single agent cannot provide for itself.

Check the confirmation status of a transaction by hash on Base/Polygon/Arbitrum/Optimism/Ethereum: success / failed / pending / not found, with block, from, to, gas used. Read-only. ?hash=0x…&network=base

Pull emails, URLs, IPv4s, @mentions, and #hashtags out of free text. Returns deduped lists.

Flesch Reading Ease score and Flesch–Kincaid grade level for English text, plus word/sentence/syllable counts.

Convert CSV into a GitHub-flavored Markdown table (first row is the header).

Parse an IPv4 CIDR block: network address, broadcast, first/last host, netmask, and host count. Optionally test if an IP is inside it.

Financial math. op: "compound" (future value of principal at a rate) or "loan" (monthly payment + total for a loan).

Lookup a Farcaster profile by username or FID. Returns FID, username, display name, bio, profile picture URL, follower/following counts, and the canonical Warpcast URL. Use to label cast authors, validate a Farcaster handle, or fetch a profile for display.

Current gas snapshot across Ethereum + supported L2s (Base, Polygon, Arbitrum, Optimism), sorted cheapest-first. Returns gas price in gwei, latest block number, chain id, and an isL2 flag per chain. Use to route a transaction to the cheapest viable L2 or to track L1→L2 gas spread.

List Kalshi markets (CFTC-regulated US event contracts). Filter by status (open/closed/settled/unopened) or by event ticker. Returns yes/no bid/ask, last price, volume, open interest. Complement to Polymarket for US-regulated markets and Kalshi-only categories (weather, economic data).

Top L2s by TVL via DeFiLlama. Returns each L2 with TVL in USD, native token symbol, and CoinGecko/CMC ids. Classification combines DeFiLlama's parent-chain hint with a curated list of well-known L2s (Arbitrum, Optimism, Base, zkSync Era, Linea, Scroll, Mantle, Polygon zkEVM, Starknet, Blast, Mode, Manta, Metis, Polygon, Taiko, Immutable zkEVM, World Chain).

Recent sales for an NFT collection (or specific token) on any of 5 chains, ordered descending by block. Returns buyer, seller, marketplace (OpenSea/LooksRare/X2Y2/Blur), price (units + wei), protocol/royalty fees, tx hash, block, and quantity for each sale. Use to track volume, detect wash trades by repeat buyer/seller pairs, or chart a collection's price trajectory.

Historical odds (implied probabilities) for a Polymarket outcome token. Returns timestamped price samples with first/last/min/max summary. Useful for: tracking probability shifts around events, computing realized volatility, backtesting prediction strategies.

Search active Polymarket markets by keyword. Returns the top matches sorted by 24h volume, with question, current outcome prices (implied probabilities), volume, liquidity, end date, and CLOB token ids for orderbook lookups.
