Broke to Built

Generate QR codes via API. Input: content (URL, text, WiFi, vCard and more) plus optional size, margin, colors, and error-correction level. Output: hosted PNG and SVG image URLs ready to embed or download. $0.02 per QR code generated.

Security headers checker for any URL: pass a list of URLs, get one JSON record per URL with the observed CSP, HSTS, X-Frame-Options and related headers, missing-header findings, and an A–F security grade. $0.02 per URL checked.

Scan a page's cookies: each Set-Cookie parsed with Secure/HttpOnly/SameSite/expiry, third-party & tracker flags, GDPR category, security issues. Bulk. $0.0008 per page, cheaper than paid GDPR scanners; failed fetches free.

Extract a YouTube transcript without an API key: clean text, timestamps, and SRT. Batch URLs, auto or manual captions. $0.004 per transcript — videos without captions are never charged.

Barcode PNGs by API: QR, Code128, EAN-13/8, UPC-A/E, ITF-14, DataMatrix, PDF417, Aztec + more (bwip-js engine). Retail check digits VALIDATED — a wrong EAN check digit is rejected free, not rendered broken (release-tested). $0.0015 per barcode vs $0.002-$0.004 measured incumbents. 50 per run.

Convert CSV files to Excel spreadsheets by URL - proper quoted-field parsing, custom delimiters, headers detected, column widths set. Batch up to 25 files. Built for scripts, pipelines, and AI agents. $0.03 per file; failures are free.

Check up to 500 emails/domains per run against a 7,582-domain disposable blocklist + keyword and pattern heuristics, with ~30 legit webmail providers whitelisted. $0.0005 per check, no start fee, invalid inputs never charged — half the cheapest measured incumbent.

Input: one domain or up to 100 domains. Output per domain: the WHOIS registration date, exact age in days and years, and a maturity class (new under 1y, established 1-5y, mature 5y+). A fast first filter for vetting sites, prospects and backlinks at scale. $0.02 per domain checked.

Fetch any website's favicon and get it back as a base64 data URI plus a hosted PNG/ICO file URL, with content-type and real pixel dimensions. Bulk. $0.001 per icon, below paid favicon fetchers; failed fetches free.

Radix conversion that never corrupts big values: BigInt throughout, so 2^64-1 converts exactly (floats fail past 2^53). Bases 2-36, 0x/0o/0b prefixes just work, negatives get 8/16/32/64-bit two's-complement views, bit/byte lengths included. $0.0004 per conversion; invalid digits never charged.

Analyze password strength — entropy in bits, crack-time estimate, and specific weaknesses (common passwords, patterns, repeats). Privacy-safe: nothing is stored. $0.0004 per password analyzed.

Trace any URL redirect chain: every 301/302 hop with status code and Location, the final destination, hop count, plus redirect loops, long chains, insecure http hops and 302-vs-301 issues. Expands short links too. Bulk input, no API key, $0.02 per URL, no start fee.

Analyze any XML sitemap in one call: auto-discovery via robots.txt, URL counts, sitemapindex vs urlset detection, size, lastmod and HTTPS issue flags. $0.02 per site analyzed — flat, no per-URL charges.

Discover every feed a site exposes: declared link rel=alternate RSS/Atom/JSON plus common feed paths, validated & de-duplicated. Bulk. $0.0004 per page, cheaper than the measured comparable; failed fetches free.

Extract every link from any webpage. Input: a list of page URLs. Output: JSON with the absolute link URL, anchor text, internal/external type and rel flags (nofollow, sponsored, ugc), plus mailto and tel lists. $0.01 per page flat, however many links it finds. No start fee, no browser, no code.

Extract webpage metadata from any URL. Input a URL, get one JSON record with the page title, meta tags, OpenGraph, Twitter Card, and JSON-LD structured data. $0.02 per page analyzed — for link previews, SEO checks, and AI agent pipelines.

Extract all structured data from any page - JSON-LD, Microdata, and RDFa - plus the schema.org types found. Single or bulk. $0.0004 per page, cheaper than every paid structured-data actor measured; failed fetches are free.

Convert any well-formed XML by URL into clean JSON - attributes preserved, repeated elements as arrays, root element reported. Configs, API responses, RSS feeds, sitemaps. $0.02 per file; fetch/parse failures are free.

Scrape YouTube comments without an API key or cookies: top-level plus replies, top or newest sort, exact like counts (not rounded), author channel IDs, batch videos. $0.0004 per comment. Videos with comments turned off are never charged.
