{chain} path param is a friendly slug. Map of slug → CAIP-2
chain ID + Aegis coverage below.
Aegis full coverage is currently limited to ETH, BSC, TRON —
the only chains where we ingest the full transaction graph end to
end. Other chains return
400 unsupported_network.
Aegis is the single verdict surface. Where the on-chain graph is
sparse, additional commercial scoring runs under the hood (opt-in) and
is folded into the same Aegis verdict — there is no separate
multi-provider tier to select.
Address format
A wrong-case TRON address won’t be found in our index — a
0x6b17…
EVM address can be sent in any case and we’ll normalise.
Settlement chain
Independent of{chain}. Today the x402 quote always settles on
Base mainnet (or Base Sepolia for testnet calls), regardless of
which chain you’re querying. Multi-chain settlement is on the
roadmap.
