Broke to Built

Convert Markdown to safe GitHub-flavored HTML by URL or text - anchored headings, table of contents, script/iframe stripping. Bulk. $0.0005 per conversion; failures are free.

Paste-ready TOC for any markdown doc or URL: GitHub-compatible anchors, nested indentation, duplicate headings deduped, code fences ignored, setext + ATX parsed, links stripped from heading text. Up to 50 docs per run. $0.0008 per document, unfetchable URLs never charged.

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.

Audit a page's external links with evidence per link: rel/nofollow/sponsored flags, unsafe target=_blank (tabnabbing), non-HTTPS, live HEAD/GET status probes + redirect resolution. Up to 1,000 links/page. $0.005 per page incl. probes vs $0.04 measured incumbent; unreachable pages never charged.

Extract a PDF's metadata by URL: page count, version, title, author, producer, keywords, dates and a text preview, without full parsing. Single or bulk, up to 25 per run. $0.003 per PDF, no start fee; failures are recorded free.

Screen up to 1,000 texts per run against a tiered profanity wordlist with obfuscation heuristics (leet, spacing, partial masks) — severity, exact positions, masked cleanedText, Scunthorpe-guarded boundaries. A filter, NOT an AI moderation system. $0.0004 per text, junk entries never charged.

Test up to 50 regex patterns against sample text by API: all matches with indexes + named groups, plain-English pattern explanation, ReDoS heuristics and a 4s time-box so catastrophic patterns report instead of hanging.

Test URLs against robots.txt with real Google semantics: longest-match, Allow wins ties, UA group selection (test Googlebot, GPTBot, ClaudeBot...), wildcards. Verdict + the exact rule that decided it + sitemaps. $0.0008 per URL, invalid URLs never charged — vs $0.001-$0.15 measured incumbents.

Parse and audit any site's robots.txt in one call: user-agent groups, allow/disallow rules, declared sitemaps, and crawl-block issues like an accidental site-wide Disallow. $0.02 per site analyzed. No API key.

Watch RSS and Atom feeds and get only what changed since the last run. Keeps a baseline between scheduled runs, separates new items from edited ones, ignores tracking-parameter churn, and never floods you on run one. From $0.001 per feed checked on paid plans; failures free.

Watch RSS and Atom feeds and get only what changed since the last run. Keeps a baseline between scheduled runs, separates new items from edited ones, ignores tracking-parameter churn, and never floods you on run one. $0.005 per feed checked; feeds that fail to fetch or parse are never charged.

RSS feed parser for developers and AI agents: pass any RSS or Atom feed URL as input and get back clean, structured JSON items (title, link, date, and other feed fields). $0.02 per feed parsed — cost scales with feeds, nothing hidden.

Crawl a site and get back a finished audit report with your agency name and brand colour on it. Findings grouped by severity, each explaining why it costs traffic. Self-contained HTML that prints to PDF. One flat price per report — from $2.99 on paid plans.

Bulk URL slugs with real transliteration: diacritics, Cyrillic, Greek, symbol words (& -> and), batch-unique suffixes on collisions, custom separator + maxLength. Up to 200 per run. $0.0004 per slug, unsluggable inputs never charged. Release-tested on the non-ASCII cases naive slugifiers eat.

See how any URL looks when shared on social: the rendered preview (title, description, image) from Open Graph and Twitter Card tags, with missing-tag issues flagged. $0.02 per URL checked. No API key.

Validate SPF for up to 200 domains per run: parsed mechanisms, DNS lookup count vs the RFC 7208 limit of 10, all-qualifier and plain-English issues. $0.0008 per domain, no start fee, failures never charged — cheaper than measured incumbents ($0.001+/item). For deliverability and security audits.

Convert SRT to VTT or VTT to SRT, strip timings to a plain text transcript, and resync cues by any offset. Paste text or pass up to 50 file URLs. Handles optional VTT hours, comma vs dot decimals and NOTE blocks. $0.005 per file; files with no cues are free.

Live TLS handshake for up to 200 hosts per run: issuer, SANs, days-to-expiry, full chain walk, negotiated protocol, self-signed/expired diagnosis with exact error. $0.0008 per host, no start fee, unreachable hosts never charged — cheaper than measured incumbents ($0.001-$0.035).

Scrape any public Telegram channel: post text, publish date, view counts, photo/video flags, forward and reply markers, and a direct link. One row per post, pages past the 20 a page shows, bulk channels. No API key or login. $0.01 per post.

Round-trip case conversion done right: camelCase, PascalCase, snake_case, kebab, CONSTANT_CASE, Title, Sentence, dot.case, slug — with correct acronym splitting (parseHTMLParserOutput -> parse_html_parser_output). 200 texts/run. $0.0004 per text all nine cases; junk never charged.

Regex extraction of 11 structured entity types from up to 100 texts per run: emails, phones, URLs, IPs, dates, times, money, percentages, hashtags, mentions + Luhn-checked ALWAYS-MASKED cards. Not model NER — exact, private, in-process. $0.0008 per text all types, junk entries never charged.

Extract ranked multi-word keyword phrases (RAKE-scored) + top words from up to 200 texts per run. For tagging, SEO briefs, ticket clustering, labeling scraped content. $0.0005 per text, no start fee, junk entries never charged. No paid keyword-extraction rival with defined pricing measured.

Detect the language of up to 200 texts per run: ISO 639-3 code, English name, confidence and ranked alternatives (franc trigram model, in-process, texts never leave the run). $0.0005 per text — half the measured incumbent ($0.001); too-short snippets never charged. For routing and dataset splitting.

Score up to 100 texts per run with Flesch, Flesch-Kincaid, Gunning Fog, SMOG, ARI and Coleman-Liau + consensus grade, audience label and concrete fix-it tips. $0.0004 per text all six formulas, no start fee, word-free inputs never charged — vs $0.0005-$0.015 measured incumbents.
