# PG1 Sovereign Threat Intelligence

> Threat intelligence agent for AI agents and security tooling. Free skills: wallet sanctions screening (check_wallet_sanctions), domain age (check_domain_age), hostname/phishing reputation (check_hostname_reputation), wallet age/history (check_wallet_age), pre-install npm/PyPI package checks (check_package), bring-your-own-key AbuseIPDB IP lookups (check_ip_abuse; your own key in the X-AbuseIPDB-Key header), x402 endpoint and agent card checks (check_x402_endpoint, check_agent_card), a pre-read check of another agent's message or a seller's skill.md for prompt injection and payment manipulation (check_agent_message), signature verification (verify_result) and free-tier usage status (get_usage_status). Paid skills: one-call preflight before an agent acts (preflight_check), a hosting advisor (hosting_advisor), CVE enrichment (single, batch, by product) and MITRE ATT&CK threat actor dossiers, 0.01 USD per call via x402 (a2a-x402 extension: the PaymentPayload in message.metadata["x402.payment.payload"]), a Gumroad licence key in X-API-KEY, after 5 free calls a day per caller (automatic; shared with the MCP server at /api/mcp; X-Free-Tier: 0 skips them). The STIX feed of CVE records from NIST NVD (free (CVE records from NIST NVD); does not use the 5 free paid calls a day; the operator's PG1_FEED_PAID switch can make it paid) and the record lookups stay on /api/mcp and /api/ioc. Paid jobs: batch wallet screens (up to 500), CVE exposure reports (PDF + JSON), hostname/package batch checks (up to 200) and threat write-up PDFs, quoted then paid over a2a-x402 (submit_job). Commissioned tools: build_tool. Every result is signed (Ed25519).

## Skills
- **preflight_check** — One call before an agent acts. Give the action (pay, open, install, patch, trust_agent) and its target; PG1 runs every relevant check in parallel and returns on
- **hosting_advisor** — Ranked hosting regions and providers for a workload, with cited reasons: data-protection regime, published government data-access frameworks, provider acceptabl

- **check_domain_age** — Looks up a domain's registration age via RDAP (the IANA-standardized WHOIS successor). Always free. A newly registered domain (age_days < 30) is reported as a c
- **check_hostname_reputation** — Checks a single hostname against the MetaMask eth-phishing-detect blocklist/allowlist plus a lookalike/typosquat detector, synced daily. Always free; rate-limit
- **check_wallet_age** — Reports when an EVM wallet address first appeared on a given chain, based on its earliest on-chain transfer history (in or out), plus whether it's a contract. A

- **check_package** — Check before you install: a pre-install check of one npm or PyPI package. Always free, no AI model; rate-limited to 60 calls/hour per caller without a Gumroad l
- **check_x402_endpoint** — Check an x402 endpoint before paying it: reads its 402 payment request, then screens payTo against the sanctions list and its on-chain age, checks the network a
- **check_agent_card** — Check another agent before trusting it: fetches its A2A agent card, validates the schema, flags a name that claims a brand its domain does not belong to, and ch
- **check_agent_message** — Check a message from another agent, or a seller's skill.md, before your own model reads it: PG1's deterministic rules (no AI model) for instruction override and
- **verify_result** — Verify a PG1 result's Ed25519 signature against PG1's published keys (/.well-known/pg1-signing-key). Always free. Give result and signature, and optionally the 
- **get_usage_status** — Returns your remaining free-tier calls for today and current Gumroad license status. Always free.
- **get_cve_details** — Enriched lookup of one CVE: NVD description and CVSS, CISA Known Exploited Vulnerabilities status (and the FIRST EPSS score only when PG1 serves EPSS in paid re
- **get_cve_batch** — The same CVE enrichment for up to 20 CVE ids in one call; malformed or unknown ids are reported per entry. Paid: 0.01 USD via x402 or a licence key, after the s
