pricing

Every endpoint this server fronts, with its exact per-call USD price (x402, USDC on Base) and a one-line summary, read live from the route table. Free.

request_data

The suggestion box: ask for data we don't have (a pre-2015 filing, an uncovered ticker, an unsupported chain, a whole dataset). Requests feed the nightly ingestion queue — filings are usually availabl…

gas_price

Bid-ready EIP-1559 fees (slow/standard/fast maxFeePerGas + maxPriorityFeePerGas, tx-ready wei) for one chain, read live from public RPCs. Pass tx_type to get the USD cost of that specific transaction …

gas_compare

Rank every supported chain by all-in USD transaction cost — the 'where should I send this' routing decision, with the OP-stack L1 data fee included. Paid: call without x_payment to receive this call's…

spot_price

Live Chainlink on-chain spot price for an asset (latestRoundData, with round metadata). Pass `to` as well to cross-convert two assets via their USD feeds, with both legs reported. Paid: call without x…

Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to…

swap_quote

Indicative UniswapV2 swap quote from live on-chain reserves: amount out, execution price, and price impact — what the trade will actually cost before you sign it. Paid: call without x_payment to recei…

ens_resolve

Resolve an ENS name to an address, or an address to its forward-verified primary name — direction is detected from the input. view='profile' returns the full identity card (multichain addresses, text …

chain_info

Canonical record for an EVM chain — name, native currency, explorers, liveness-scored public RPCs. view='rpcs' returns only the ranked, eth_chainId-probed RPC list; view='wallet_config' returns a read…

nft_scam_check

Deterministic scam checklist with a verdict and evidence (spam flags, copymint collisions, holder concentration). Pass a collection contract to check the collection, or a wallet to check that wallet's…

pre-trade-check

Everything to verify before signing a swap: is the token a trap, what will the trade price at, and what will the gas cost.
