Lightweight deterministic line/word/char diff. Structured ops or unified output.

Hallucination check: a live fact-check of one claim by four independent AI models (GPT, Gemini, Grok, Claude), each searching the web separately. Returns a summary first: verdict (confirmed, disputed, unverifiable, or contested when the models split), agreement such as 4/4, mean confidence and a one-line headline. Then each model's verdict, reasoning and cited sources. Disagreement is shown, not hidden. 10-45 s.

Use when you need South Korea's official public holidays for a year (business-day calculation, scheduling, settlement and payroll calendars).

Output: JSON list with date, weekday, Korean and English name, isPublicHoliday, kind. Example: ?year=2026

Not 'is this address sanctioned' (that's sanctions) but 'has it DEALT with one' — screens a wallet's USDC counterparties (both directions) against the OFAC SDN list. Taint by association: receiving from or routing through a wallet that transacts with sanctioned addresses carries sanctions risk. Returns the sanctioned counterparties found. Covers direct counterparties; pair with fund-trace for the multi-hop funding chain. Not financial advice.

Settlement/value date: T+n business days across national statutory calendars (intersected), with the market cycle cited to its primary source and a per-day trail

Do two tokens share the same recent holders — the farm / sybil / coordinated-launch signal nobody else surfaces? Reads each token's recent recipients and returns the overlap as a share of the smaller set: independent (the few % unrelated tokens share via routers/power users), overlapping, or strongly_linked (a coordinated cohort — same farm, deployer community, or a sybil set rotating between them). Pass a= and b=. A signal, not proof. Not financial advice.

🆕 Resolves the complete Base identity behind an address or Basename: resolved address, avatar, description, website and social handles (X/Twitter, GitHub, Farcaster, Discord) read from Base's L2 Resolver text records. Lets an agent turn a counterparty address into a real profile — beyond just the name. Complements address-trust (verification) with the human context.

The address-poisoning attack: a scammer sends dust from an address whose first/last characters match one you really use, hoping you copy-paste the poisoned one. An auto-paying agent is the perfect victim. This compares the recipient against the head/tail of addresses the wallet actually transacts with and flags a look-alike that is NOT a real counterparty. Pass wallet= (yours) and to= (the recipient). A heuristic — verify the full address regardless. Not financial advice.

A quote shows today's price; it does NOT tell you a $5k buy into a $20k pool pays ~20% more. This takes the token's deepest Base pool, treats it as constant-product (Uniswap-V2 / Aerodrome volatile) and computes the exact x*y=k price impact for your USD size. Conservative — concentrated-liquidity pools usually do better. Also returns the largest size under 1% and 3% impact. Pass address= and size= (USD). An estimate; confirm with swap-route. Not financial advice.

Not price momentum — ADOPTION. token-age tells you when a token was born; holder-distribution is a snapshot. Neither shows the TRAJECTORY. A token can pass every static check and still bleed users week over week — what a human sees watching for days, an agent can't. Reads weekly transfer counts and distinct participants over the last 28 days and calls it: accelerating, steady, cooling, dying, or low_activity. Activity ≠ price; pair with wash-trading. Not financial advice.

owner-powers says the owner CAN mint; this says whether they ARE, and how fast. A token can advertise fixed supply and quietly inflate it, diluting holders before the dump. Sums zero-address mints and burns over a window (CDP SQL) against live on-chain totalSupply, annualised. Verdict from fixed_in_window / deflationary to hyperinflation. Honest: bridges, staking and LP programs mint legitimately — flags the RATE, not intent. Not financial advice.

Before your agent sends, approves or signs to an address — a wallet risk check with one GO/REVIEW/STOP verdict. Screens OFAC sanctions, Coinbase/Basename identity, wallet vs contract, how long the address has existed, and whether contract logic can be swapped AFTER you send. Every factor returns what it found and what it could not read — a check that did not run never reads as clean, so GO means everything material was actually screened. Not financial advice.
