List a country's holidays for a calendar year (optionally by state/region, language and type).

Photo to 3D Model (high detail): Photo to 3D model (high-detail tier, 1-3 min). Single input image to a high-poly textured GLB with PBR-like shading and a preview thumbnail. Game-ready — drop straight into Three.js, Unity, or Godot. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/photo_to_3d_hq.

Shift a non-negative integer left or right by `amount` bits. A right shift is logical (fills with zeros). A left shift grows freely unless a `width` is given, in which case the result is masked to that width and the input must fit it. Returns decimal, hex and binary.

Builds a PKCS#12 container holding certificates only, for the common case where a runtime insists on PKCS#12 as its trust store format. The password is explicitly empty and reported back as such, so nothing depends on an undocumented default, and the reply states outright that the store contains no private keys. That matters: a PKCS#12 file is the usual carrier for a key, and a consumer must be able to tell a trust store from an identity store without opening it.

Creates an image from scratch from a text description. Choose the quality tier with image_generator_version: hd, genius, or super_genius for the highest detail at 2k output. The genius tier also takes an art style in genius_preference: classic, anime, photography, graphic, or cinematic. Returns a link to the generated image.

Takes a public key in SubjectPublicKeyInfo PEM form and runs the pinned OpenSSL build's own consistency checks over it, then reports the algorithm, the key size in bits and the parameters it found. This catches keys that parse but are structurally unusable: a modulus that is not a valid product, curve parameters that do not match a known group, a size that no longer meets the build's security level. The reported bit count comes from the key itself, not from the label a producer attached.

Decode a base64, base64url, hex, base32, or URL percent-encoded string back into UTF-8 text. Malformed input for the chosen encoding is rejected as a clean 400.

Takes two documents, by URL, inline base64 or raw text, extracts the text of each and compares them. Paragraphs are the unit: the answer lists every block that was removed, added, or kept but reworded, and for reworded blocks it names the individual words that went and came, so a single changed number in a long clause is visible instead of the whole clause being flagged. Alongside the content diff a structural comparison reports headings, paragraph, list and table-line counts on both sides.

Cost in USDC of a transaction with the given gas at current and next base fee (?gas=21000)

Use when an agent or user wants a moment of delight — one warm original fortune, a lucky number (1-99), and a calm word from the Synthetic Universe. Pure compute, no upstream. Optional session id avoids repeats. Use permitted: build it into your products and services, paid or free. Raw redistribution of the feed itself is prohibited.

Bitwise OR across two or more non-negative integers (given as decimal strings, evaluated as arbitrary-precision BigInt). Returns the result in decimal, hex and binary.

Resolve one company name through Pipe0 company:identity@3. At-cost fixed cap: max($0.01, 0.30 Pipe0 credits × $999/34,000 credits). Useful as a lightweight first step, fallback, or corroboration step before Crustdata enrichment workflows.

Creates an image from scratch from a text description. Choose the quality tier with image_generator_version: hd, genius, or super_genius for the highest detail at 2k output. The genius tier also takes an art style in genius_preference: classic, anime, photography, graphic, or cinematic. Returns a link to the generated image.

Diff two texts. The default `unified` mode returns a unified-diff patch string; `lines`, `words`, and `chars` modes return a structured array of added/removed/unchanged parts.

Encode a UTF-8 string into base64, base64url, hex, base32, or URL percent-encoding.

Cheapest entry point: one-call COT snapshot. Report dates, top 3 crowded-long and crowded-short markets by 52-week COT index, biggest week-over-week spec move, universe counts. From the same 438-market CFTC dataset as the premium endpoints.

Inspect a non-negative integer's bit structure: bit length, set-bit count (population count), trailing-zero count, power-of-two test, and hex/binary representations. An optional width zero-pads the binary form.

Runs the pinned OpenSSL build against a submitted certificate request and answers two questions a registration authority has to settle before it signs anything: does the request carry a valid self-signature over its own body, and what exactly is being requested. The reply names the subject, the public key parameters and every requested extension as OpenSSL parses them, so a policy check compares against the parsed request rather than the text an applicant supplied.

Apply an RFC 6902 JSON Patch to a JSON document and return the result. An invalid or unresolvable patch (e.g. a failed `test`, or a path that does not exist) is rejected before payment.
