Business days between dates. Count business (working) days between two dates, skipping weekends and public holidays for the US, UK, Sweden, Germany, France, Norway, Denmark or Finland, and list the holidays skipped; or give add=N to get the date N business days after (or before) a date. Other countries count weekends only, and the answer says so. Use for delivery estimates, SLAs, payment terms and payroll dates.

Favicon finder. Find a website's icons: every <link rel=icon>, shortcut icon, apple-touch-icon and mask-icon on the page with its size and type, the web app manifest link, and whether /favicon.ico exists, all as absolute URLs, with the best icon picked (SVG, then the largest size; mask icons never). Use to show a site's logo next to a link, build bookmarks or enrich a company record.

OpenAPI spec summary. Read an OpenAPI 3 or Swagger 2 document (JSON or YAML, up to 2 MB) from a URL and summarise it for an agent: title, version, description, servers, auth schemes, operation count by method, tags, which operations are paid (402 or x-payment-info) or deprecated, and up to 150 operations with method, path, summary and operationId. Use before calling an unfamiliar API, to pick an endpoint, or to compare APIs.

Web answer, AI with citations. Answer a question from the live web in one call: a Brave web search, the top result pages read, and an answer written by Llama 4 Scout from those sources only, with inline [n] citations and the source list (title, URL). Says so when the sources do not answer it. Results are for the caller's immediate use only: no storing, resale or model training (Brave API terms). Use when an agent needs a current, sourced answer rather than raw search results.

Zodiac sign from a birth date. Western (tropical) zodiac sign with its element, and the Chinese zodiac animal and element of a birth date. The Chinese year is counted from the Gregorian year, so dates in January and early February before Chinese New Year are flagged as possibly the previous animal. Use for profile enrichment, greeting cards, games or horoscope-style content.

DNS records lookup. Look up DNS records of a domain over DNS-over-HTTPS (Cloudflare 1.1.1.1): A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, PTR, DS, DNSKEY or HTTPS, with each answer's TTL, the response code (NOERROR, NXDOMAIN…) and whether DNSSEC validated. Use to check email (MX, SPF in TXT), verify a domain, or debug a DNS change; for whether the change has spread use dns_propagation.

DNS propagation check. Check whether a DNS change has propagated: the same record queried at five public resolvers (Cloudflare, Google, AdGuard, AliDNS and DNSPod), each resolver's answers and TTLs, whether they all agree, and the majority answer. Record types A, AAAA, CNAME, MX, NS, TXT, CAA. Use to see where an old value is still cached after changing a record, moving hosting or setting up email; for one lookup use dns_lookup.

Fact check, verify a claim. Check a claim against the live web in one call: a Brave search, the top pages read, and a verdict from Llama 4 Scout using those sources only (supported, contradicted, mixed or unverified) with a short explanation, [n] citations and the sources. A model's reading of a few search results, not an editorial fact-check. Results are for immediate use only (Brave API terms). Use to screen a statement before an agent repeats or acts on it.

DeepSeek R1 reasoning model API. Chat with DeepSeek's R1 reasoning model distilled into Qwen 32B (MIT) through one paid HTTP call: send a prompt and an optional system prompt, get the answer, up to 2,048 output tokens; its reasoning is removed from the answer. Also reachable as model "deepseek-r1" on the OpenAI-compatible /v1/chat/completions. No account or provider key. Use when an agent wants this model by name.

Get contents, web contents. Read one to five public web pages in one call and get each one's clean text (or Markdown), title, author and published date where the page declares them, in the request shape search APIs use (urls as a list). Pages are read in parallel; one that cannot be read is listed in statuses with its reason and the rest still answer. Static HTML, Markdown and plain text, up to 20,000 characters a page. Use to read search results in one call.

Contract ABI, verified contract. The verified ABI of a smart contract on Ethereum, Base, Arbitrum, Optimism or Polygon from Sourcify's open verification repository: contract name, compiler, match quality, every function and event signature, the full ABI, and for proxies the implementation contract with its ABI. Optional source=true adds the main source file (up to 20,000 characters). Unverified contracts are an uncharged 404. Use before calling or decoding a contract.

Clinical trials search. Search ClinicalTrials.gov studies by condition, intervention or any words, optionally only recruiting ones: NCT id, title, status, phase, conditions, interventions, sponsor, enrollment, start and completion dates, number of locations and countries, and a link. From the ClinicalTrials.gov API (US National Library of Medicine). Information only, not medical advice. Use to find trials for a condition or drug.

Reverse geocoding. Turn latitude and longitude into place names: the nearest populated place and the largest one within the radius (usually the town or city the point is in), with country and ISO code, administrative region, population, distance and Wikidata id, plus the other places nearby. Data from Wikidata (CC0). Use to label GPS points, photos, deliveries or IP-derived coordinates; for place name to coordinates use geocode.

HTML table to JSON. Extract every table from an HTML fragment into JSON: header cells become keys and each body row an object (or raw arrays when there is no header row), with captions, colspans repeated and entities decoded. Give the HTML itself (up to 500 KB). Use to turn web or email tables into data an agent can sort and compute on; to fetch a page first use extract.

GPT-OSS 120B chat API. Chat with OpenAI's open-weight gpt-oss-120b reasoning model (Apache 2.0) through one paid HTTP call: send a prompt and an optional system prompt, get the answer, up to 1,024 output tokens. Also reachable as model "gpt-oss-120b" on the OpenAI-compatible /v1/chat/completions. No account or provider key. Use when an agent wants this model by name.

News sentiment. The news on a topic and its tone in one call: the latest headlines from the Brave News index (title, URL, publisher, age), each with a positive or negative score from a DistilBERT model, and the balance across them. Up to 10 articles from the past day, week or month. Not a market signal. Results are for the caller's immediate use only (Brave API terms). Use for a market mood check, brand monitoring or a news brief.

Federal Register search. Search the US Federal Register: final rules, proposed rules, notices and presidential documents, newest first, with title, type, agencies, abstract, publication date, comment deadline, effective date and links. Filter by type and agency. From the Federal Register API (US government work). Use to track new regulations or open comment periods on a topic.

Web research. One call to research a question on the web: a Brave web search, then the text of the top 1-5 result pages, read in parallel and clipped to your length, with titles and URLs. A page that cannot be read is listed with its reason. Results are for the caller's immediate use only: no storing, resale or model training (Brave API terms). Use when an agent needs current, sourced information in one step instead of a search plus several page reads.

URL safety check, scam signals. Check a link before an agent opens or pays it: where it really leads (each redirect hop, the final URL), the destination domain's age, registrar and trust flags, HTTPS and security headers, and named risk signals (days-old domain, bare IP host, punycode look-alike, user@host trick, chains across many hosts). Heuristic signals from public facts, not a phishing blocklist. Use to vet links in emails, chats and scraped pages, or a payee's website.

PII detection and redaction. Find personal data in a text and get it back redacted: emails, phone numbers, card numbers (Luhn-checked), IBANs (mod-97), US SSNs, IP and crypto wallet addresses, each with its position, plus the text with every hit replaced by a label such as [EMAIL]. Hits are shown masked. Up to 20,000 characters; names and street addresses are not detected. Use before logging, storing or sending text to a model.
