Search, fetch and extract in one call: top results with page text and the elements matching a CSS selector.

Cross-store pricing for a single game — Steam, Epic, GOG and Microsoft Store side by side — with the lowest price ever observed, the date it was observed, and how far above that low the current price sits. Storefronts publish today's price and no history, so the low exists only for whoever recorded it; ours runs from 2012. Every response resolves the game's family so a base game is never compared against a season pass.

Validate and normalize phone numbers (Google libphonenumber): validity, E.164/international/national formats, country, region, and line type (mobile/fixed/VoIP). Single number or batches up to 100.

Compute the exact probability distribution of a dice notation — mean, variance, standard deviation, min/max and the full probability mass function — with no sampling. Notations whose outcome range is too large for exact computation are clean 400s.

Compute the RFC 6902 JSON Patch that transforms `source` into `target`. The patch is a minimal array of add/remove/replace operations.

Check a domain's BIMI record (<selector>._bimi, default selector, with fallback to the organisational domain): v=BIMI1 syntax, HTTPS logo and certificate URLs, an SVG logo path and whether DMARC is enforced at quarantine or reject with pct=100. Use when an agent must tell why a brand logo does not show in mail clients. The logo and certificate are not downloaded.

Inspect an unknown payload or string and detect whether it looks like JSON, JWT, Base64, hexadecimal, or URL-encoded data without executing code. Useful for payload identification, encoding detection, and deciding how to decode opaque input.

Flatten a nested object/array into a single-level object whose keys are the delimited paths to each leaf (default delimiter `.`). Requires an object or array.

Evaluate a domain's CAA records (RFC 8659), climbing to parent names up to the registrable domain when the name has none: allowed issuers for normal and wildcard certificates, iodef, unknown critical tags and invalid values. Use when an agent must tell which certificate authorities may issue for a domain, or why a certificate request is refused because of CAA.

Search functions or classes by meaning and by keyword. ``mode=bm25`` ranks by lexical match, ``mode=vector`` by embedding similarity to the query text, and ``mode=hybrid`` (default) fuses both rankings with reciprocal rank fusion. Returns up to ``top_k`` matches with their repository, file path and score; the ``domain``, ``ontology_concept_uri``, ``confidence_min`` and ``has_tests`` filters apply to Function results only.

Report a domain's DNSSEC status (secure, insecure, bogus or unknown) as validated by public resolvers, with DS and DNSKEY algorithms, deprecated algorithms, SHA-1 digests and DS records without a matching key. Use when an agent must tell whether a domain is signed, why it fails on validating resolvers, or whether a key rollover left the chain of trust broken.

Country trade history from World Bank WDI: imports and exports of goods and services in current USD and as % of GDP. ISO3 country, last 1-10 complete years, independent latest values, units, nulls, source update date and CC BY attribution. Annual national-account totals, not bilateral flows, product-level trade, tariffs or shipments; USD values are not inflation-adjusted.

Runs the pinned OpenSSL build's parameter checks over a supplied finite-field Diffie-Hellman group and reports whether it passes, along with the detail output that says why. The point is to catch parameters that are syntactically fine but cryptographically unsafe before they reach a handshake: a non-prime modulus, a generator of small order, a group below the build's security level.

Checks a detached OpenPGP signature against the bytes it claims to cover, using the pinned GnuPG build and nothing else. What comes back is the verdict in GnuPG's own terms, the fingerprint that actually signed, the signature timestamp, the algorithms used, and whether the key is expired or revoked. A wrong key, a tampered byte or a signature made by someone else each produce a distinct verdict rather than a bare false.

Xynaptic Crypto Fear & Greed — the market sentiment thermometer (alternative.me index, 0-100): current value, yesterday, last week, classification (extreme fear..extreme greed) + interpretation hint for agents. GET no params.

Embeds one query and up to 64 candidates locally, then returns cosine scores and stable descending ranks.

Rebuild a nested object from a single-level object whose keys are delimited paths (default delimiter `.`) — the inverse of flatten. Requires a flat object.

Transform payload data through 1 to 12 deterministic steps in one call, including Base64 encode/decode, hex encode/decode, URL encode/decode, JSON parse/canonicalize, and SHA256/SHA512 hashing. Useful for multi-step data transformation, payload processing, encoding pipelines, decoding pipelines, and chained transformations.

Website screenshot: capture any public URL as an image in a real headless Chrome, with its text. See a web page the way a person does: pass ?url= and get a 1280x900 screenshot (JPEG, base64) of the first screen, rendered in a real headless Chrome with JavaScript executed, plus the page title, its full visible text and its links. Bot walls and empty renders are refused before any charge. Paid in USDC on Base.
