NOT F
- `onchain\_agent\_get\_contract\_facts`: USE WHEN you need the canonical address or id of something on a chain and want it with its source and date instead of from memory: a protocol's deployment \(Uniswap Permit2, a Safe singleton, Multicall3, the ERC-4337 EntryPoint, an ERC-8004 registry\), the USDC contract and CCTP domain Circle states f
- `onchain\_agent\_get\_chain\_card`: USE WHEN you are about to build for or deploy to a chain and want its dated facts in one call: registry entry, USDC and CCTP domain, ERC-8004 registry deployment, which public RPC endpoints support state-override calls and eth\_simulateV1, which x402 facilitators list it, and reported activity. NOT F
- `onchain\_agent\_get\_x402\_facilitators`: USE WHEN an agent has to pay or charge with x402 and needs to know which facilitator lists a chain, a scheme and a protocol version, how recently each one actually answered, and which ones could not be read \(key wall, unreachable\), so "none lists it" is never mistaken for "all were checked".
