Price list
What each endpoint costs
Prices track real work, not a flat average - a cached DNS answer does not subsidise a crawl that makes thirty requests.
| Endpoint | Category | Credits | Why |
|---|---|---|---|
dns-lookupDNS Lookup | Network & DNS | 1 | One DNS query, answered in milliseconds and served from cache when the record is still fresh. This is the cheapest class of call on the platform. |
ip-lookupIP Address Lookup | Network & DNS | 1 | One cached lookup against a geolocation dataset. Repeat lookups of the same address inside the cache window cost us nothing extra. |
reverse-ipReverse IP Lookup | Network & DNS | 1 | A single reverse DNS query - the same cost profile as a forward lookup. |
hash-textHash Text | Hashing & Passwords | 1 | Pure CPU, measured in microseconds, with no outbound call. Priced at the platform floor. |
qr-generateQR Code Generator | Data & Utility | 1 | Pure CPU image generation, a few milliseconds, with no outbound call. |
currency-ratesCurrency Exchange Rates | Data & Utility | 1 | Served from a shared cache that is refreshed on a schedule rather than per call, so an individual request is close to free for us. |
gold-priceGold & Silver Price | Data & Utility | 1 | One or two cached outbound lookups - the one-credit floor. |
ssl-checkSSL Certificate Check | Network & DNS | 2 | Requires a real TLS handshake with the target host, which costs a round trip and some CPU for certificate parsing - a few times the work of a cached DNS answer. |
http-requestHTTP Request | Web & HTTP | 2 | One outbound request to a host we do not control, held open until it answers or times out. Priced above a DNS query because the response body must be read and buffered. |
redirect-chainRedirect Chain Tracer | Web & HTTP | 2 | Makes one request per hop rather than a single fetch. Most chains are one to three hops, so this is priced as a small multiple of a plain request. |
seo-metaSEO Meta Tag Extractor | SEO & Content | 2 | One page fetch plus parsing. The parse is pure CPU and negligible; the cost is the outbound request and reading the HTML. |
bcrypt-hashBCrypt Hash | Hashing & Passwords | 2 | BCrypt is deliberately expensive by design: a work factor of 11 is roughly a tenth of a second of dedicated CPU. Priced above a plain digest because that CPU time is the entire point of the algorithm. |
bcrypt-verifyBCrypt Verify | Hashing & Passwords | 2 | Verification runs the same deliberately slow key derivation as hashing, at whatever work factor is embedded in the supplied hash. |
pdf-metadataPDF Metadata Reader | Documents | 2 | Parses only the PDF's header and information dictionary rather than rendering pages, but the file still has to be uploaded and read, which is why it sits above the one-credit floor. |
pingPing Host | Network & DNS | 2 | Holds a socket open for a few seconds per run - more than a DNS lookup, far less than a browser. |
watermark-imageWatermark Image | Images | 2 | One download plus a pure-CPU raster pass - cheap, but it moves bytes. |
argon2-hashArgon2 Hash | Hashing & Passwords | 3 | Argon2id is memory-hard: each call allocates and works over a sizeable block of RAM, so it consumes both CPU and memory that cannot be shared with other requests. It is the most expensive pure-CPU tool here. |
argon2-verifyArgon2 Verify | Hashing & Passwords | 3 | Runs the same memory-hard derivation as hashing, at the parameters embedded in the supplied hash. |
smtp-testSMTP Server Test | Network & DNS | 3 | A multi-step protocol session with a TLS handshake, held open for several seconds. |
web-scrapeWeb Page Scraper | Web & HTTP | 3 | Downloads and parses a whole page, which is several times the work of a metadata-only fetch. |
broken-linksBroken Link Checker | Web & HTTP | 10 | Fetches the page and then up to 30 more URLs, five at a time - about 31 outbound requests for a single call. Priced to reflect that fan-out. Lower maxLinks when you only need a spot check; the price is flat, so a smaller crawl is simply better value per link. |
word-to-pdfWord to PDF | Documents | 15 | Spins LibreOffice on a worker for several seconds per file, which is far more compute than a DNS lookup. Priced so a loop of conversions cannot quietly drain the worker. |
ppt-to-pdfPowerPoint to PDF | Documents | 15 | Same LibreOffice worker cost as Word to PDF - one deck, several seconds of CPU. |
pdf-to-wordPDF to Word | Documents | 20 | Layout-preserving PDF reconstruction is heavier than Office-to-PDF and is capped by page count on the worker. |
pdf-to-excelPDF to Excel | Documents | 20 | Table extraction walks every page and builds a workbook - similar worker time to PDF-to-Word. |
pdf-to-pptPDF to PowerPoint | Documents | 20 | Each page becomes a slide, so worker time scales with page count like the other PDF-to-Office tools. |
remove-backgroundRemove Background | Images | 25 | Runs an ONNX segmentation model on the worker. That is GPU/CPU-heavy compared with hashing or DNS, so it sits well above the one-credit floor. |
website-screenshotWebsite Screenshot | Images | 25 | Every call starts and tears down a headless Chromium instance, which is an order of magnitude heavier than an HTTP fetch. |
html-to-imageHTML to Image | Images | 25 | Identical work to a URL capture: one headless Chromium instance per call. |
image-upscaleAI Image Upscale | Images | 30 | Real-ESRGAN is the heaviest synchronous job in the catalogue. One call can occupy the worker for tens of seconds. |
The rules
What you are charged for
Successful calls cost the endpoint’s listed price.
Invalid requests are free. If your arguments fail validation, nothing is charged - the call never runs.
Our failures are refunded. A timeout or fault on our side is credited straight back and shown on your statement.
Your target’s failures are charged. If you point a tool at a host that is down, we still did the work of trying.
Every call returns your balance in the X-Credits-Remaining header, so you can track spend without a second request.
