Find API docs, developer portal, candidate base URLs and auth docs.

Resolve public product or listing availability with explicit normalized states. It reports only provider evidence and never infers inventory, reserves items or places an order.

Report whether a public item appears buyable with explicit blockers such as out-of-stock or unknown. This is a preflight only: it never signs in, buys, creates an order or guarantees checkout.

Resolve a public product redirect, canonical URL and stable provider identifiers using bounded HTTP and structured data. It does not execute JavaScript or assert unavailable facts.

Preflight an item into a fresh isolated commerce session without touching a customer cart. Sessions are ephemeral and payment/order creation is never attempted.

Cheaply detect material public product changes in price, availability, selected variant or seller using a deterministic hash. Timestamps, images and analytics noise are excluded.

Check whether an isolated cart can reach checkout and expose blockers without payment. It never logs in, creates an order or finalizes checkout.

Report public delivery options for an isolated ephemeral cart and destination when the provider exposes them. No customer cart, payment or order is touched.

Return a normalized current offer price for a public product or listing. Provider fields missing from the source remain null; no price prediction, purchase or customer authentication is performed.

Extract public SKU, GTIN, UPC, EAN, ISBN, MPN and provider identifiers from a product source. Missing identifiers stay null and are never guessed.

Normalize a public product URL into current title, selected variant, price, currency, availability and buyability. Uses bounded read-only provider responses or JSON-LD; it never buys, logs in or guarantees unpublished stock.

Check a requested quantity against public variant constraints and known availability. Unknown stock remains unknown; this capability never reserves or purchases inventory.

Resolve requested product options to a canonical public variant when the provider exposes them. Ambiguous or missing options are reported explicitly; no checkout or cart mutation occurs.

Perform a bounded static discovery pass for machine-usable documentation: llms.txt, Markdown alternates, developer/API/auth docs, OpenAPI/Swagger and MCP candidates. Candidates are returned only after bounded verification. Maximum 10 HTTP requests, no JavaScript, recursive crawl or authenticated content.

MX/SPF/DMARC preflight; not mailbox verification.

Resolve a bare public domain into operational registration, DNS, HTTPS/TLS and mail-policy state using IANA-routed RDAP, DNS, MX/TXT/SPF/DMARC and a bounded TLS probe. No registrant personal data, vulnerability scanning, mailbox existence or deliverability claim. Provider uncertainty is explicit.

Registration/registrar/expiry/status without unrelated domain checks.

Return the current public application route; do not submit application.

Cheap watchdog for closed/materially changed job state.

Normalize compensation explicitly published by the job source; never infer missing salary.

Return structured application fields/questions where publicly exposed.

Normalize whether a public job is still published/open and its canonical apply route.

Detect material marketplace listing changes in active state, price, seller, condition or quantity with a deterministic hash. It does not place bids, purchases or infer hidden listing facts.

Normalize public marketplace listing activity, offer, seller, condition and quantity hints. eBay credentials are optional configuration; no buying, bidding or seller mutation is supported.

Return seller identity and publicly published seller signals for a marketplace listing. Missing feedback or business fields remain null; no customer or seller account access is attempted.

Find public MCP server candidates and registry metadata.

Read-only MCP handshake/tools-list preflight; no destructive tool calls.

Verify OpenAPI/Swagger document reachability, parseability, operations/auth/servers.

Normalize declared package license metadata toward SPDX; no legal compatibility conclusion.

Normalize npm or PyPI package reality: existence, requested-version existence, resolved/latest version, staleness, deprecation/yank state when available, license and runtime requirement. No dependency graph or vulnerability analysis. Public registries only; unsupported provider fields are null.

Known vulnerabilities for package+version; normalized evidence, not a safety verdict.

Extract PDF/CSV/XLS/XLSX/ZIP/JSON/XML links from static public HTML by suffix or download filename. Resolve relative/base links and deduplicate. Limits: 500 links, 8s, 5 redirects, 2 MiB. No JavaScript or file downloads; existence, MIME, size and file safety are unverified. Empty results are valid. 0.003 Base Sepolia test USDC per success; invalid inputs/errors are not settled.

Resolve a public GitHub release into the most plausible downloadable asset for a normalized OS/architecture target, excluding source/signature/checksum files and linking checksum companions when present. Returns ambiguity instead of silently choosing tied candidates. No private repositories or customer authentication.

Find checksum/signature companion assets for a release asset.

Check whether a repository has a usable latest/tagged release before deployment/download.

Cheap watchdog: material service state changed since prior canonical hash?

Resolve the live state of a named service component.

Return active service incidents in normalized form.

Normalize a public Atlassian Statuspage into operational, maintenance, degraded, partial_outage, major_outage or unknown state, with components, active incidents and scheduled maintenance. V1 accepts an explicit status-page URL; it does not discover arbitrary providers or infer hidden service health.

Inspect a public URL with HEAD; GET only on 405/501. Return origin status, final URL, headers, cache validators and up to 5 redirects. Limits: 8s, 2 MiB. Origin 4xx/5xx are observations; length is unverified and SHA256 covers only complete GET bodies. No JavaScript, login or availability guarantee. 0.001 Base Sepolia test USDC per success; invalid inputs/errors are not settled.

Search machine-payable x402 resources and normalize discovery metadata.

Read-only probe of x402 PaymentRequired requirements; does not pay.
