Every agent-payable API.

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

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

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

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 Uses bounded read-only provider responses or JSON-LD; it never buys, logs in or guarantees unpublished stock.

MX/SPF/DMARC preflight; not mailbox verification.

Return active service incidents in normalized form.

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.

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

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.

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

Cheap watchdog for closed/materially changed job state.

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

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

Find public MCP server candidates and registry metadata.

Resolve the live state of a named service component.

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

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

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

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.

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.

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

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.

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.

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

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

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.

Find public MCP server candidates and registry metadata.

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

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

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

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

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

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

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.

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

Cheap watchdog for closed/materially changed job state.

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

Return only the public certificate validity window and remaining lifetime for TLS port 443. It does not scan ciphers, vulnerabilities or private hosts.

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.

Return structured application fields/questions where publicly exposed.

Resolve the current public GitHub repository state without cloning or customer OAuth. Archived, fork, branch and license fields reflect only public API facts; private repositories are unsupported.

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.

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.

Check an anonymously readable OCI image tag and resolve its manifest digest through the standard Distribution API. No blob pull, push, delete or private registry access is performed.

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.

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 mainnet USDC per success; invalid inputs/errors are not settled.

Search machine-payable x402 resources and normalize discovery metadata.

Find checksum/signature companion assets for a release asset.

MX/SPF/DMARC preflight; not mailbox verification.
