Every agent-payable API.

Useful for fact-checking page history, finding deleted content and due-diligence. Use this when an agent needs to how the Internet Archive remembers a URL.

Convert between wei, kwei, mwei, gwei, microether, milliether and ether with exact BigInt arithmetic. Decimal strings of any magnitude convert without floating-point error. Use this when an agent needs to exact Ethereum unit conversion — no float errors.

Explain what an EVM transaction would actually do: decodes the calldata (ERC-20 transfers/approvals via known ABIs, unknown selectors via the 4byte directory) and simulates the call against live chain state to report the outcome — including unlimited-approval warnings — without sending anything. Use this when an agent needs to decode and simulate a transaction — before signing it.

Top holders of any NFT collection with exact quantities, individual and cumulative ownership percentages, and concentration statistics — the distribution picture agents need before valuing or recommending a collection.

One-call on-chain profile of any Ethereum or Base wallet via Blockscout: native balance, transaction and transfer counts, activity recency, top token holdings, and most frequent recent counterparties — with fresh-wallet and high-volume flags. The 'who is this address?' conclusion, not raw RPC data. Use this when an agent needs to on-chain wallet profile: balance, activity, tokens, counterparties.

Validate an email address in two layers: strict RFC-style syntax, then a live DNS MX lookup on the domain to confirm the recipient actually runs mail servers. Catches the typos and fake domains that pure regex misses. Use this when an agent needs to syntax + live MX check — can this address receive mail?.

Live foreign-exchange reference rates from the European Central Bank (via frankfurter.dev): a full rate table against any base currency, or cross-rate conversion of any amount. Refreshed every business day by the ECB, cached one hour. Use this when an agent needs to live ECB reference rates for 30 currencies.

Split text into retrieval-friendly chunks with a token budget and sentence-aware boundaries. Overlap between consecutive chunks preserves context across splits — the standard preparation step before embedding. Use this when an agent needs to rAG-ready chunks with token budgets and overlap.

Live cryptocurrency prices from CoinGecko's public API: current price in USD/EUR/GBP/JPY plus 24-hour change for any coin by id or common ticker (btc, eth, sol…). Cached 60 seconds. Use this when an agent needs to live token prices and 24h change via CoinGecko.

Convert area units: square millimeters, centimeters, meters and kilometers, hectares, acres, square feet and square miles. Use this when an agent needs to square meters, feet, acres, hectares.
