Merges SEC EDGAR (www.sec.gov/files/company_tickers.json + data.sec.gov/submissions, public domain) with GLEIF's LEI reference API (api.gleif.org, CC0 open data) — a global scope broader than the category leader's French-registry-only data. Accepts `q` as an…
POST/weather$0.004Weather ($0.004): current conditions + short forecast, worldwide. United States coordinates (or a resolvable U.S. street address) read live from the National Weather Service's own public API (api.weather.gov), U.S. government data, plus active alerts.

POST/archive_tip_day$0.01Tip/entry ($0.01): tip receipt (brand+date+content hash, no payTo) PLUS one Signal archive day unlock. Body { date: YYYY-MM-DD }. First-penny path into Signal archive — primary CTA remains signal_latest $0.03.

POST/sec_late_filing_feed$0.03SEC Late-Filing Feed ($0.03): Form NT 10-K / NT 10-Q late-filing notices with resolution status (still-late vs resolved, days to resolution) — a going-concern/compliance signal generic EDGAR-listing tools do not surface.

POST/kyb_pack$0.05KYB Due-Diligence Pack ($0.05): one call merging company_lookup (SEC EDGAR + GLEIF LEI), sanctions_screen (OFAC SDN name + wallet), domain_intel (RDAP + DNS posture), wallet_profile (Base activity/balances/OFAC), and email_validate (syntax + live MX/DNS) into a single report with per-section status, sources, and a flags summary -- instead of a compliance/onboarding agent making up to 5 separate sub-cent calls and merging them itself. Only the sections implied by the body actually run, in…
POST/peer_origin_offer$0.03Partnership slot ($0.03): other x402 origins pay to append origin_url + short pitch into OUR peer catalog. Body { origin_url, pitch, contact? }. HTTPS-only SSRF checks (no private IPs). Free thin list at GET /peers. Different buyer than Signal readers.

Body { address (or q) } for forward…
