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.

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.

The coins most searched on CoinGecko right now, ranked, with market-cap rank, price and 24h change. A global attention/discovery feed for agents hunting what's moving — distinct from trending-tokens, which is Base-DEX specific. An attention signal, not quality or safety: vet anything here with token-risk before touching it. Not financial advice.

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.

Convert an amount between wei, kwei, mwei, gwei, szabo, finney and ether — or between any token decimals (pass a number like 6 for USDC). Integer-exact, no precision loss. Pass amount, from, to. Pure compute, sub-cent — the unit-conversion commodity agents call constantly when building transactions. Not financial advice.

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.

Reads the deepest pool's 24h volume, buy/sell counts, liquidity and price move, and scores how organic the activity looks. Volume 10x+ the pool's liquidity, near-perfect buy/sell symmetry, or big volume that moves the price nowhere are the classic wash-trading signatures used to bait buyers. Returns a 0-100 suspicion score and verdict.

Live cross-asset market data: the top coins ranked by market cap with price, market cap, 24h change and volume (CoinGecko). The global snapshot an agent reads before trading — our other price tools are Base-token-address based; this is the whole market. Pass limit= (up to 100) and vs= (usd/eur/…). Not financial advice.

Looks up a person from an email, name, domain, or company and returns a normalized public-data record (alias of people-enrich). Includes inferred display name, free-email detection, MX records, and optional public company context. Public-data only; no private people databases or LinkedIn scraping. Use it as a people lookup, people API, or person lookup.

Converts a datetime from one IANA timezone to another with correct DST handling. ISO-8601 input: bare wall-time strings are interpreted in the from_tz, fully-qualified offsets are honored. DST is handled correctly (uses V8's built-in tzdata via Intl.DateTimeFormat). Returns both formatted strings, both UTC offsets, and the difference in hours. Use it for DST-aware time arithmetic, wall-clock to UTC conversion, or converting across cities.

Decision Leg invalidations. Per-call USDC.

Enriches a contact from email, name, domain, or company into a normalized public-data record with inferred display name, company/domain context, MX records, and optional homepage metadata. No private people database, LinkedIn scraping, or social-network scraping. Use it as a contact enrichment API, email-to-contact enrichment, or lead contact lookup.

txpeek (Tanod) pre-transaction check: risk verdict for an address in about a second (proxy and admin control, verification, risky functions, token basics). Heuristic, not an audit. Use when an agent is about to send funds to or call an address and wants a quick risk check first.

End-of-day OHLCV bars for every US-listed ticker on a single date; one call returns the entire market. Pass `?date=YYYY-MM-DD` (required). From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

Direct CFTC Traders in Financial Futures asset-manager/institutional long, short, spread and net positioning for CME Micro Ether, including open-interest share. Purpose: Measure current CFTC asset-manager net positioning in CME Micro Ether as an institutional positioning sensor without converting it into a directional recommendation. 168-hour freshness target; missing evidence is reported explicitly rather than invented.

Latest available Malaysia consumer price inflation plus a comparable annual history from the World Bank World Development Indicators API, with source, lag and revision caveats.
