One id in, its official lifecycle state out - no need to know which line tracks it first. Covers 19 lifecycle lines (stablecoins, AI tools and datasets, neoclouds, DePIN, RWA, carbon projects, ESG funds, tariff measures and more): status band, birth/end dates, death type, lifespan, official source_ref. If two lines track the same id you get BOTH - nothing is picked for you. Unknown id -> 422 no_charge, not billed. Every record carries an offline-recomputable record_hash.

Token safety check before buying or interacting: given an ERC20 contract on Base, returns risk_score 0-100 and verdict.

Red flags surface honeypot/rug indicators. For AI trading agent pre-transaction due diligence, automated token vetting, rug-pull avoidance.

Validates a UserOperation structurally and against chain state. It computes the required prefund from the gas limits and fee fields, reads the sender deposit on the EntryPoint and, when a paymaster is set, that paymaster deposit and stake, and says plainly whether the operation is funded. The nonce is read from the EntryPoint and compared with the one supplied, so a stale nonce is caught before submission.

Reads a Safe from the public transaction service and returns what decides whether it can act: the owner set, the threshold, the current nonce, any enabled modules and the guard contract, and the master copy version. Queued transactions are listed with the confirmations they already carry and the number still missing, so it is visible which of them are one signature away from executing.
