- US CPI Data & Inflation Reportcpi-report-us.underscoredone.comGives you official United States inflation numbers from the government's BLS Consumer Price Index. Ask for the newest reading, a specific month in the past, or a whole range of months, and get back clear percentages for overall inflation and 'core' inflation (which ignores food and energy prices), plus a plain-English summary sentence.Livechecked Evidence 1/4x402x402 Bazaar9 payers
- CORS Header Checkercors-header-checker.underscoredone.comSends a real request to any URL you provide, attaches an Origin header, and reads back all six standard cross-origin permission headers the server returns. Tells you whether cross-origin requests are enabled at all, whether your specific origin is permitted, and shows every permission value exactly as the server sent it. Useful for finding why a browser is blocking a request, confirming a new deployment is configured correctly, or auditing whether a public API allows credentialed calls.Livechecked Evidence 1/4x402x402 Bazaar7 payers
- TCP Port Scannerport-scanner.underscoredone.comGive this API a hostname or IP address and it tries connecting to each port in your requested range. For every port that answers it reports whether it is open or blocked, which service is likely running there (a web server, SSH), and what software version was detected. Saves you installing network tools, parsing command-line output, or writing socket loops. Only scan hosts you own or have permission to scan - this tool does not check that for you.Livechecked Evidence 1/4x402x402 Bazaar6 payers
- BIMI Checkerbimi-checker.underscoredone.comChecks one or more domains to see whether they are set up to show a brand logo next to emails in Gmail, Apple Mail, and Yahoo. It looks up the BIMI settings the domain has published, checks the logo file follows the required format, checks any logo certificate is valid and unexpired, and confirms the domain has strict enough email protection turned on. Returns a clear pass or fail per domain, plus a plain list of what is broken when something fails.Livechecked Evidence 1/4x402x402 Bazaar6 payers
- ENS Resolverens-resolver.underscoredone.comLook up an ENS name or an Ethereum address and get back the matching one, automatically figuring out which direction you need.Livechecked Evidence 1/4x402x402 Bazaar6 payers
- JSON Validate, Repair, Convert,json-suite.underscoredone.comEvery agent and developer hits broken or confusing JSON. This tool handles the common headaches in one place: check whether JSON is valid with the exact error location, repair near-JSON with typos, pretty-print or minify, pull values out with a path expression, diff two documents, convert to and from YAML or CSV, produce a byte-stable canonical form for hashing, validate against a schema, and report size and structure. Same input, same output, no side effects.Livechecked Evidence 1/4x402x402 Bazaar6 payers
- Mortgage & Loan Amortization Calmortgage-amortization.underscoredone.comGive this API a loan amount, an interest rate, and a repayment term, and it returns the exact monthly payment plus a full month-by-month schedule: interest paid, principal repaid, and balance remaining for every payment. Ask what an extra $300 a month, or a $10,000 lump sum in month 24, would do and it reports the months and interest saved. Every figure uses banker's rounding at pinned precision, so two correct systems agree to the cent. You supply the rate; the API does the math.Livechecked Evidence 1/4x402x402 Bazaar6 payers
- ASN Lookupasn-lookup.underscoredone.comGiven an internet address (IP) or a network identification number (ASN), this tool returns who operates that piece of the internet: the network number, the owner's name, the country it's registered in, the regional registry that manages it, and the exact address range it belongs to.Livechecked Evidence 1/4x402x402 Bazaar5 payers
- URL Uptime Checkerurl-uptime-checker.underscoredone.comChecks whether a website or web address is currently reachable and reports how fast it responded.Livechecked Evidence 1/4x402x402 Bazaar4 payers
- DNS & WHOIS Lookupdns-whois-lookup.underscoredone.comSend up to 10 domain names and get back every DNS record type (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) plus the full WHOIS registration profile (registrar, dates, contacts, status, nameservers) for each one. URLs are accepted and automatically stripped down to the bare domain. Duplicate domains are quietly removed before processing. Results come back as one flat row per domain, ready to drop into a spreadsheet, database, or pipeline.Livechecked Evidence 1/4x402x402 Bazaar4 payers
- Curl HTTP Requestcurl-http-request.underscoredone.comSend an HTTP request to any URL from our servers and receive the full response — including the status code, all response headers, and the body content. Supports GET, POST, PUT, PATCH, DELETE, and HEAD. Automatically follows up to 3 redirects. Useful for testing endpoints, verifying servers are responding correctly, debugging redirect chains, or fetching raw data without needing a local setup.Livechecked Evidence 1/4x402x402 Bazaar4 payers
- Hacker News Datahackernews-data.underscoredone.comThis tool reads live information from Hacker News, a popular website where people share and discuss technology news. You can either ask for a current list of stories (like the Top, New, Best, Ask, Show, or Job lists) or ask for every story, job posting, and poll that was posted on one specific calendar day in the past. You can also choose to pull in the discussion comments underneath each story, including nested replies several levels deep.Livechecked Evidence 1/4x402x402 Bazaar4 payers
- Domain Availability Checkerdomain-availability-checker.underscoredone.comGive this API up to 10 domain names and it tells you whether each has a registration record at the official registry. It uses RDAP, the structured replacement for WHOIS, so there is no free-text parsing. Each domain comes back as 'registered', 'unregistered', or 'indeterminate' when the registry has no RDAP for that ending. 'Unregistered' means no record was found, which usually means available - but reserved and premium names also return no record. Registration status only; no pricing.Livechecked Evidence 1/4x402x402 Bazaar4 payers
- Shopify AI Rank Checkershopify-ai-rank-checker.underscoredone.comChecks how well a Shopify store's products show up when AI shopping assistants such as ChatGPT, Gemini, Perplexity, Grok, and Copilot search for products, and reports the store's rank and its closest competitors. Searches Shopify's real Global Catalog - the same product index AI assistants read from.Livechecked Evidence 1/4x402x402 Bazaar4 payers
- Domain Age Checkerdomain-age-checker.underscoredone.comSend a list of domain names and this tool tells you exactly how old each one is, when it was first registered, when it expires, and how much time is left before expiration. Great for spotting brand-new suspicious domains, researching competitors, or evaluating domains before buying or linking to them. Works with over 100 domain extensions worldwide.Livechecked Evidence 1/4x402x402 Bazaar3 payers
- SEO Data Extractorseo-data-extractor.underscoredone.comGive this API a web address and it will visit that page, then hand back everything an SEO professional needs to know: the page title, meta description, meta keywords, robots instructions, canonical link, H1/H2/H3 headings, how many links are on the page, and the HTTP status code. No setup required — just paste a URL and get structured data back in under two seconds.Livechecked Evidence 1/4x402x402 Bazaar3 payers
- Bulk DMARC Record Lookupdmarc-lookup.underscoredone.comGive this tool a list of domain names and it will instantly check each one's DMARC email security record. DMARC is a standard that tells email providers how to handle fake or spoofed emails pretending to come from your domain. For each domain you submit, you get back whether a valid record exists, what the policy is (none, quarantine, or reject), whether reporting addresses are set up, and the full raw record text. Perfect for auditing many domains at once without any setup.Livechecked Evidence 1/4x402x402 Bazaar3 payers
- Hashing, HMAC & Checksum Suitehash-hmac.underscoredone.comGive this API any text or binary data and it returns its fingerprint under whichever hash algorithms you choose - SHA-256, SHA-512, MD5, BLAKE2, CRC32 and more. It also signs data with a secret key (HMAC) and safely verifies whether an incoming signature matches, using a timing-safe comparison. Language models cannot hash: they emit a string of the right length and character set that is simply wrong, so every webhook check built on a guessed hash is silently broken.Livechecked Evidence 1/4x402x402 Bazaar3 payers
- Email Verifier & Validatoremail-verifier.underscoredone.comTakes one email address and tells you whether it can actually receive mail. Returns a verdict of valid, invalid, or risky, splits the address into username and domain, and flags free providers and role accounts like admin@ or support@. One address per call.Livechecked Evidence 1/4x402x402 Bazaar2 payers
- Sitemap URL Extractorsitemap-url-extractor.underscoredone.comGive this API a link to any website's sitemap.xml file and it will fetch and parse it, returning every URL found inside. If the sitemap links to other sitemaps (called sitemap indexes), it will follow and extract those too. Each URL is returned with any extra information available, such as when the page was last updated and how often it changes. Useful for SEO audits, content inventories, broken link checks, and competitive research.Livechecked Evidence 1/4x402x402 Bazaar2 payers
- HTTP Status Code Checkerhttp-status-checker.underscoredone.comGive this API a list of up to 10 web addresses and it will visit each one to tell you whether it is working, broken, or redirecting visitors somewhere else. You get back the exact status number (like 200 for OK, 404 for not found, 500 for server error), whether the address redirects, and where it redirects to. Great for finding broken links, verifying website migrations, and running quick SEO audits without writing any code.Livechecked Evidence 1/4x402x402 Bazaar2 payers
- Leetspeak Translatorleetspeak-translator.underscoredone.comTakes a piece of text and either turns it into leetspeak (swapping some letters for numbers and symbols, like 'hello' becoming 'h3110') or turns leetspeak back into normal, easy-to-read words. The same words always produce the same result, so answers never change unexpectedly.Livechecked Evidence 1/4x402x402 Bazaar2 payers
- HTTP Header Checkerhttp-header-checker.underscoredone.comSends a request to a web address you provide and reports back everything the server said in response: the status code, all the response headers, how many times it got redirected, and how long the whole thing took.Livechecked Evidence 1/4x402x402 Bazaar1 payer
