Full website audit in one call: accessibility (WCAG 2.1 A/AA via axe-core), on-page SEO, HTTP security headers and page speed / page weight, from a single browser load of one URL. Cheaper than four separate calls; if any part cannot run, nothing is billed. Use a single audit route when you need only one of the four.

SEO audit of a web page (on-page SEO check) for any live URL or raw HTML: title tag, meta description, H1 heading structure, canonical link, OpenGraph and social tags, JSON-LD structured data, html lang attribute. Rule-by-rule findings with severity and what is missing or malformed.

Website accessibility audit (a11y, WCAG compliance check): WCAG 2.1 level A and AA conformance of any live URL or raw HTML, tested with axe-core in a real headless browser. Returns every violation with rule id, impact, help text and affected node count. Deterministic rules; a check that cannot run returns an error, never a pass.

Crypto price / live coin quote: spot price, 24-hour change and 24-hour volume for Bitcoin, Ethereum, Solana or any Coinbase product (BTC-USD, ETH-USD, SOL-USD...), read at call time from Coinbase's public market data. Use it when an agent needs a current cryptocurrency price. Input: product_id such as BTC-USD. Bid/ask: market.ticker. Whole rate table: market.rates.

Security headers check for a website: audits HTTPS, HSTS, Content- Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options / clickjacking protection, Referrer-Policy and CORS from the real HTTP response of any live URL. Findings with severity for what is missing. Header posture only, not a penetration test.

Page speed and page weight audit of a web page from one real browser load: total bytes transferred, HTTP request count and DOM node count, measured rather than estimated, with findings when the page is heavy. Page-weight signals, not Core Web Vitals.

Email verification / email validation: will mail to this address arrive? Checked live at the source: syntax, the domain's DNS (MX, null MX, no such domain) and its own mail server, asked whether the mailbox exists and whether it accepts any address (catch-all). No message sent. Flags disposable domains, role accounts (info@), free providers and typos (gmial.com). Verdict: deliverable, undeliverable, risky or unknown, with the reason. Input: email.

Mastodon data, live and keyless (any public instance): a hashtag timeline, an account with its latest posts, account or hashtag search, or trending hashtags, each post with text, counts, media and tags. Use it for social listening and trend tracking in the fediverse. Input: mode (hashtag, account, search, trends) with tag, acct or query; optional instance, limit.

Non-government identity intelligence: email/DNS/wallet challenge proofs, GitHub and Bluesky public profiles, GLEIF/SEC business records, signed A2A cards and the canonical Base ERC-8004 registry. Separates ownership from public-record matches and unverified claims, with evidence, timestamps and fraud indicators. Required evidence failures refuse delivery. Existing contact screening remains available. No documents or biometrics.

Phone number validation and lookup: valid or not, country and area, the carrier the range was issued to, line type (mobile, landline, toll-free, VoIP, premium), time zones and E.164, international and national formats, from Google's libphonenumber numbering plans. Nothing is dialled and the owner is never looked up. Input: number; optional region for a national-format number.

Crypto ticker / bid and ask: live best bid, best ask, last price and volume for one Coinbase product from Coinbase's Exchange data host, an independent second source to market.quote. Input: product_id such as BTC-USD.

Exchange rates / currency conversion table: Coinbase's full rate table for one base currency against every crypto and fiat currency it quotes (USD to BTC, ETH, EUR, GBP, JPY...). Use it to convert amounts between currencies. Input: currency code such as USD.

IP geolocation / IP address lookup: city, region, country and coordinates, the network's ASN and organisation, reverse DNS, and whether the address is public, private or reserved. IPv4 and IPv6. Location data from DB-IP Lite (CC BY 4.0, credited), updated monthly; location is the network's registered place, never a street address. Input: ip.

Base network status and gas price: current block height and gas price (wei and gwei), live from a Base mainnet RPC node. Use it to check Base is moving, time an on-chain action or estimate gas before sending a transaction. Keyless, pay per call. No input needed.

YouTube search and video stats, live: search YouTube or look up videos by id, each with title, channel, upload time, duration, views, likes, comments, live flag and thumbnail from the YouTube Data API at call time. Sort by relevance, date, views or rating; filter by upload date, country and language. Input: query or video_ids; optional max_results, order, published_after, region_code.

Bluesky data, live and keyless: a profile with its latest posts and engagement (likes, reposts, replies, quotes), an account search, or a post thread with its replies, from the public AppView. Use it for social listening and influencer checks on Bluesky. Input: mode (profile, search_actors, thread) with actor, query or uri; optional posts, limit, depth.

Sanctions screening (AML/KYC): screen a person, company, vessel or aircraft against the OFAC SDN and consolidated lists, the UK Sanctions List and the EU financial sanctions list, read from the governments' own files with each list's date returned. Fuzzy and word-order free: aliases and typos match, a different surname does not. Each hit: list, programmes, countries, birth dates, UN reference. Input: name; optional type, country, birth_year.

Top prediction market events: Polymarket events (groups of related markets) ranked by trading volume, with title, slug, end date and market count. Use it to see what the biggest prediction markets are right now. Input: optional limit.

Prediction market odds: live Polymarket markets on any topic (elections, Fed rate cuts, crypto, sports, AI, geopolitics) with the probability each outcome implies as a percentage, plus volume, liquidity and end date. Search by topic words or tickers (BTC, 'fed rate cut') or take the biggest markets. A topic no open market matches is refused free, never sold empty. Input: optional query, limit. One market by slug: prediction.market.

Stock price / live stock quote for any US ticker: last price, change, day range, volume and market state, plus daily OHLCV history (1d to 5y), read at call time from Nasdaq's public data with Yahoo Finance as fallback. Every answer names its source, the source's timestamp, its delay in minutes and when it was read. Input: symbol (AAPL, NVDA...); optional range, include_history.

SEC filings / company fundamentals: revenue, net income, diluted EPS, operating income, assets, liabilities, equity, cash and shares outstanding by quarter and year (10-K, 10-Q) as the company reported them to the SEC, from EDGAR's official XBRL API at call time. Name any other XBRL line item; restatements resolve to the latest filing. Input: symbol (US ticker) or cik; optional concepts, periods, forms.

DNS lookup and domain health check: A, AAAA, CNAME, MX, NS, TXT, CAA and SOA records asked of the source, SPF and DMARC email policy parsed, and the HTTPS certificate verified like a browser (issuer, names, expiry, days left, TLS version). Flags missing SPF or DMARC, duplicate SPF and certificates near expiry. Input: domain (a URL is accepted).

Company enrichment / firmographics by domain or name: legal and common name, founded, headcount with date, industries, headquarters, parent, CEO and founders, stock listings, LEI, SEC CIK, registration number, legal form and status, official social accounts and logo. Sources: Wikidata, the global LEI register, SEC EDGAR and the company's own site; every field names its source. Input: domain or name.

Base transaction lookup by hash: sender, recipient, ETH value, block, success or failure, gas used and log count, with the receipt folded in, live from Base mainnet. Use it to confirm a payment or transfer landed on-chain. Input: hash (the 0x transaction hash). For the raw receipt use chain.rpc.
