Basename/ENS resolution on Base: forward name->address (give 'name') or reverse address->name (give 'address', forward-verified against spoofing).

Native-coin balance + ERC-20 token balances (raw + human) for any address on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base). On Base pass token symbols or 0x addresses (or a default common set); on other networks pass explicit 0x token addresses.

Free-text web search, returns title/url/snippet list (DuckDuckGo).

Current Base L2 gas price (gwei) read from chain state (eth_gasPrice).

Fetch a public URL and return clean markdown/text + metadata (trafilatura).

Compute keccak256/sha256, a 4-byte function selector, an event topic0, or an ENS namehash/labelhash from a string or hex input.

Pure-compute data format conversion (no network): JSON<->CSV, JSON<->YAML, JSON normalize/minify, Markdown->HTML (sanitized), HTML->Markdown/text, base64/hex, TOML->JSON. Operates only on the supplied data.

Extract every link from a public page for crawling agents: de-duplicated absolute URLs with anchor text, internal/external counts, declared feeds and a sitemap hint.

Verify an EIP-191 personal_sign or EIP-712 typed-data signature and recover the signer address from public inputs (message + signature). Verification/recovery only — never signs.

ABI-encode a function call (selector + args) or encode/decode arbitrary ABI types — build and parse EVM calldata correctly.

Convert token units (wei/gwei/ether or arbitrary decimals), between hex and int, and compute/validate an EIP-55 checksummed address.

Structured parse of a public web page: main text, headings, links, tables and rich metadata (description, canonical, lang, Open Graph, Twitter cards, JSON-LD) as separate fields. Browserless, robots.txt-respecting.

Parse an RSS, Atom or JSON Feed URL into a normalized item list (title/link/published/summary/id/author) plus feed-level metadata.

GitHub repository health & intelligence for due-diligence / dependency choice: stars, forks, open issues, watchers, size, language, topics, license, archived/fork flags, and computed signals (days_since_push, age, issues_per_star, is_active). From the official GitHub REST API, normalized.

Discover and parse a site's sitemap: pass a site root (found via robots.txt or /sitemap.xml) or a direct .xml. Returns URLs with lastmod/priority; handles <sitemapindex> (one level).

Recent DEX swap history + buy/sell flow for a token or pool on Base: per-swap trader/side/amount/price plus a summary (count, buy/sell volume, net flow, largest swaps), decoded by us from public Aerodrome/Uniswap-V3 Swap event logs.

Package intelligence across npm / PyPI / crates: latest version, age, release cadence, deprecation/yank, license, and download stats (last day/week/month) with a rising/falling trend. Aggregates the official registry + downloads API + deps.dev.

Trending Base DEX pools ranked by recent swap volume and net buy/sell flow over a short window, computed by us from public Aerodrome/Uniswap-V3 Swap event logs.

Hacker News engagement / dev-sentiment for a project or topic: story count, total & average points and comments, and the top stories (title/url/points/comments/date). From the keyless HN Algolia search API.

Enrich a domain / company / email into one aggregated profile from public sources: registration (RDAP/WHOIS age, registrar, expiry, nameservers), DNS (A/AAAA/MX/NS, SPF, DMARC), TLS certificate (issuer, validity, expiry), homepage metadata (title, description, Open Graph, JSON-LD Organization, social links, role contacts) and a tech-stack detection. Each block is null-on-failure (partial, never 500). Business/domain data only — no personal data of individuals.
