Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (6)

`explain_transaction`read-only	Paid: $0.03 USDC per successful call via x402 (not charged on errors). Explains any Base or Ethereum transaction in plain English: who sent what to whom, which tokens/NFTs moved, the function called, success/failure and fee — plus the structured decoded data.
`find_defi_yields`read-only	Paid: $0.05 USDC per successful call via x402 (not charged on errors). Top DeFi yields across 16k+ pools, filtered by asset, chain, minimum TVL and risk, each with a simple explained risk tier (outlier APY, thin TVL, reward-heavy, IL exposure). Data: DefiLlama.
`list_services`read-only	Free. Lists every Checkpoint402 data service with its price, inputs, example output link and how payment works.
`new_token_safety_feed`read-only	Paid: $0.10 USDC per successful call via x402 (not charged on errors). Newly launched token pools on Base, Ethereum or BSC, each with a 0-100 safety score and explicit red flags (honeypot, unverified code, mintable, owner powers, high tax, unlocked liquidity, whale concentration). Data: GeckoTerminal + GoPlus.
`ofac_sanctions_screen`read-only	Paid: $0.05 USDC per successful call via x402 (not charged on errors). Screens a person/company name (fuzzy, alias-aware) and/or a crypto wallet address against the US Treasury OFAC SDN list, refreshed twice daily, including the extended-remarks file where most sanctioned crypto addresses are listed.
`sec_8k_company_events`read-only	Paid: $0.10 USDC per successful call via x402 (not charged on errors). Latest SEC 8-K filings — market-wide within minutes of filing, or for one ticker — with each item code translated to plain English, high-impact events flagged (earnings, CEO changes, M&A, bankruptcy, cyber incidents) and AI summaries of the filing text.

Schemas: list_tools.
