All SEC Form 4 insider transactions for one issuer (ticker or CIK), newest first, within a txn-date window

One reporting owner's SEC Form 4 transactions across every issuer they file for — track serial founders, activists, and fund principals

Aggregate insider-flow analytics for one issuer — open-market buy vs sell net flow, non-open-market breakdown, cluster-buy detection, and a per-insider ledger

Recent-window SEC Form 4 insider transactions (buys/sells), newest first — filter by transaction code, minimum USD value, and insider role

Name a US ticker and get one cited insider-flow report: every Form 4 against the company in the window with the actual transactions parsed from the filings - open-market buys and sales (who, when, how much, at what price) separated from awards, option exercises and tax withholding - aggregated per insider and as a net flow, with a grounded signal read and a downloadable transactions appendix. SEC EDGAR data, not investment advice. USDC (x402/MPP) or card (Stripe). Not cached.

Dutch bankruptcy and insolvency check against the official Central Insolvency Register of the Dutch judiciary (rechtspraak.nl). Detects published bankruptcy (faillissement), suspension of payments (surseance) and debt restructuring procedures. Best results with a KVK number. Returns procedure type, status, dates, court and a source reference per match, with explicit match-basis and coverage notes. A no_match means no publication in the currently searchable register. Companies only.

French insolvency check against BODACC, the official bulletin of civil and commercial announcements (DILA open data). Searches collective procedures (sauvegarde, redressement, liquidation judiciaire), conciliation and professional recovery announcements by SIREN. Returns judgment nature and date, court, publication date and a direct BODACC link per announcement. A no_match means no publication in the searchable set (since 2008) — no historical clearance. Companies only.

Inspect a public URL: HEAD redirect trace, DNS A/AAAA observations and security headers in one report. At most 4 targets, no page body. Includes timestamps, partial-result warnings and factual findings; no safety or reputation verdict.

Lint any x402 endpoint or payment header against the v2 spec and real CDP facilitator behavior: CAIP-2 network ids, atomic amounts, the EIP-712 domain-name trap ('USD Coin' on Base mainnet vs 'USDC' on Sepolia — wrong name = every settlement fails), the extensions echo Coinbase Bazaar requires for indexing, expired authorizations. Findings as error/warning/info with what will actually break. Built by a seller that debugged all of these in production.

Check that an x402 endpoint still returns a valid payment challenge, and read its price and recipient. Probe an x402 endpoint and report whether it still returns a valid payment challenge: HTTP status, challenge source (v2 header or legacy body), scheme, network, asset, payTo, amount in atomic units and in USDC, and a…

Complete DNS inspection in one call over DNS-over-HTTPS: A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records with TTLs — plus a derived email posture analysis (SPF present and policy, DMARC present and policy, MX count, overall assessment) that raw lookup tools don't do.

Deterministic structural failure inspection of a caller-declared control mesh. Structural evidence only; never authorizes execution. 0.01 USDC per request.

Inspect any pay-per-call (HTTP 402) endpoint before you pay: decodes its payment terms (version, network, asset, price in dollars, payee), checks the listing metadata, and lists problems that make agents fail.

Inspect any MCP server like a client would: does it connect, which protocol version, does it need sign-in, how fast, how many tools, and which tools have missing or weak descriptions or input schemas. A checklist of fixes for server owners.

Fetch a URL (following redirects) and return the final response's HTTP headers, the server banner and content-type, plus a security-header audit reporting HSTS, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy and the cross-origin policies (with the missing ones listed). No body is downloaded or parsed.

Open an SSL/TLS connection to a host and report its certificate — issuer, subject, validity window, days remaining, SANs, fingerprint and trust status.

Inspect the latest npm package release: version, license, dependency counts, engine requirements, deprecation notice and source links. Does not download or execute package code.

Inspect URL reachability, status, latency, and key headers for $0.001 USDC. Call when you need a cheap uptime preflight before paying a heavier fetch—not a full page extract and not a crawl. Returns status and timing via x402. No API key, no subscription.

Validate a UUID and report its version and variant.

Resolve a single code point (given as 'char' or 'codepoint') to its name, general category, block, script and plane. Provide exactly one of the two inputs.

Report the properties of a MAC address encoded in its first octet: unicast vs multicast (I/G bit), universal vs locally-administered (U/L bit), the broadcast address, and — for EUI-48 — the OUI and NIC portions.

Given an emoji character (or any string), return its code points and — if known — its name, category, shortcodes and tags. An unknown emoji is a successful result with `known:false`, not an error.

Break a string into its Unicode code points, each with its U+ notation, decimal value and UTF-8 / UTF-16 byte layout, plus total byte lengths.

Fetch any URL and, without paying, decode its x402 402 Payment Required challenge: price (atomic and formatted for known stablecoins), asset, network, payTo, resource, description, timeout and any input schema. Flags MPP and Bazaar discovery extensions. Returns free:true when no payment is needed. SSRF-hardened: public hosts only; private, loopback, link-local and cloud-metadata addresses are rejected.

Classify up to 100 declared measurement intervals against tolerances as pass, fail or hold. Integer millimetres; uncertainty is an absolute interval half-width, not a confidence level. No sensor verification or engineering approval.

Totals caller-measured installed file sizes and file counts. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Install-safety signals for an npm or PyPI package: registry metadata, install-script usage, OSV advisories, typosquat risk, and a 0-100 trust score.

Instant buy-or-avoid verdict for a token: send a contract address (Base, Ethereum, BSC, Arbitrum, Polygon) or a Solana mint, get a grade A to F, a label (SAFE, CAUTION, RISKY, DANGER), a 0 to 100 score and a one-line reason, built from real checks: honeypot sell simulation, buy and sell tax, mint, freeze and owner powers, holder concentration, DEX liquidity and token age. Young or illiquid tokens can never grade above C. Also returns key facts and a share_text.

Instant technical audit of ONE page: OnPage score, meta, timings and failed checks — no crawl, seconds instead of minutes

Batch wallet trust fact profiles, priced per submitted wallet: one call, up to 10 wallets, each independently signed.

Signed wallet trust fact profile: presence checks across stablecoins, governance, NFTs, staking and institutional dimensions, up to 49 checks on 27 chains. Evidence organized by dimension, no score, no opinion. Vet a counterparty wallet before an agent transacts.

Signed ECDSA attestation of on-chain wallet conditions across 38 chains: token balance, NFT ownership, EAS, Farcaster, view calls, ratio rules, and agent standing (ERC-8004 registration, ERC-7710 delegation validity with revocation proof). A verifiable boolean, never raw balances. Up to 10 conditions per pay-per-call request.

Insurance location risk score for a US street address or lat/lon. One 0-100 natural hazard score plus a score, tier and underlying factors for each of four perils: flood (FEMA flood zone), earthquake (USGS ASCE 7-22), wildfire (USFS Wildfire Risk to Communities, California and Utah state hazard zones) and hail (NOAA storm reports within 10 miles over 20 years). For property underwriting and real estate due diligence.

Insurance questions on one US address in one call: the parcel FEMA flood zone with the federal purchase-requirement rule, what NFIP policies in force in the ZIP cost, the ACS 2023 homeowners-insurance cost band by ZIP, county, and state, and a county rebuild-cost proxy per sq ft. Perfect for: 'what will insurance cost here', 'is flood coverage required here'. Sourced ESTIMATES; never a quote. National. npx @velinussage/locus-agent-skill add.

Insured data feed: pay a premium for an ETH/USD price snapshot (?premiumUsdc=, ?maxDeviationPct=, ?checkDelaySeconds=). If the real price has drifted more than your insured tolerance by the checkpoint, claim a 2x refund — a real payout for genuinely stale data, not a fabricated failure.

Replays a minted intake bundle by pack_id (same artifact files as the T54 rail), settled in Base USDC.

POST {url} of any x402 listing -> its machine-readable I/O schema (from the advertised bazaar extension or our paid-response archive), input/output examples, price, and probe-measured delivery grade. Saves a coding agent a risky test purchase against an endpoint that may not deliver. Never charged on failure.

Machine-consumable web3 integration-risk decision for buyer agents ($0.10).

IP address intelligence from official internet-registry data (RIPEstat, the RIPE NCC public API): ASN and network holder, announced prefix, RIR-registered country, abuse contact — plus reverse DNS and private/reserved-range detection. Registry truth, not commercial geolocation guesses.

Full domain intelligence via RDAP (the registries' official WHOIS successor): registration and expiry dates with computed age, registrar, EPP status codes, nameservers, DNSSEC — plus derived risk flags (newly registered, hold status, expiring) and a clean availability answer for unregistered domains. Registry data, structured JSON, no scraping.

Korean mobility and EV supply-chain intelligence, sold per query. Structured feed tracking Korea's automotive-electronics and robotics supply chain - batteries and battery materials, EV components, robot parts, actuators and reducers, semiconductors, and tier-1 suppliers to Hyundai/Kia - written from Korean primary reporting and DART filings English-language sources do not cover. Filter by date, category and keyword. Pay per query in USDC on Base or Polygon; empty results free.
