Broke to Built

Audit MX + SPF + DMARC + DKIM (9 selectors) for up to 100 domains per run: weighted 0-100 score, letter grade and copy-paste fixes. $0.002 per domain with all four checks included, no start fee, and invalid inputs or DNS failures are never charged. For cold-email prep and lead qualification.

Clean a list before you send it. Catches null-MX domains that guarantee a bounce, keeps implicit-MX domains other tools wrongly delete, flags typo domains that resolve anyway, and separates disposable from role addresses. Never charges for an address it could not resolve. $1.00 per 1,000.

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.

Search Google News by keyword and get one row per article: clean headline, publisher, link and publish date. Any language/country, recency filter from the last hour to the last year, bulk queries. $0.005 per article; empty searches are free.

Generate MD5, SHA-1, SHA-256, SHA-512 and HMAC hashes of text or a fetched file, in hex and base64 - all algorithms in one call. Bulk. $0.0005 per input; failures are free.

Encode text to HTML entities or decode entities back, with auto-direction - named, decimal & hex references, emoji-safe. Bulk. $0.0004 per operation; empty input uncharged.

Convert a page (by URL) or raw HTML to clean GitHub-Flavored Markdown - headings, links, fenced code, tables, strikethrough. Single, bulk, or inline HTML. $0.0015 per page no start fee, cheaper than paid converters; failed fetches free.

Fetch every HTTP response header of any URL, plus a security-header analysis (HSTS, CSP, X-Frame-Options) with an A-F grade and server fingerprint. Single or bulk. $0.0004 per URL, cheaper than every paid headers actor measured; failed fetches are free.

Convert an image from PNG to JPEG, or to WebP, AVIF, PNG, GIF or TIFF, with optional resizing, quality control and metadata stripping. Batch URLs in; converted files and signed download links out. $0.004 per image; failures never charged, demo run free.

Read any image URL and get dimensions, format, camera make/model, lens, ISO, shutter, aperture, focal length, capture date and GPS coordinates with a map link. Flags photos that still carry their location. Bulk up to 50. $0.003 per image; non-images are free.

Infer a draft-07 JSON Schema from any JSON URL or raw sample: types, required fields, email/date-time/uuid/uri formats, small enums, merged array-item schemas. $0.002 per schema, no start fee, non-JSON never charged — vs $0.011+ measured incumbents. Validate APIs and LLM output fast.

Convert a JSON file by URL into a downloadable CSV - column union across records, proper quoting, Excel-friendly CRLF, one CSV per array for object-of-arrays input. Up to 25 files a run. $0.02 per file; failures are free.

Evaluate up to 50 JSONPath expressions against pasted JSON or a URL: every match returned with its JSON Pointer and value, filters/wildcards/recursive descent supported (jsonpath-plus 10.3). $0.0005 per expression, no start fee, invalid expressions never charged. No paid JSONPath rival measured.

Decode up to 50 JWTs per run: header, payload, iss/sub/aud, humanized iat/exp/nbf, expiry verdict, security warnings (alg=none, no-expiry, sensitive claims). Decode ONLY — signatures never verified, tokens never transmitted anywhere. $0.002 per token vs $0.02 measured incumbent; malformed free.

Synthetic test datasets from your schema: 20 field types, persona-coherent rows (email matches the row's name), seed = fully deterministic reruns, safe demo-only email domains. $0.003 flat per dataset up to 1,000 rows — vs incumbents charging per record ($0.60/1k measured).

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.
