find_data — Describe the data you need in plain language (e.
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.
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).
gas_price — Bid-ready EIP-1559 fees (slow/standard/fast maxFeePerGas + maxPriorityFeePerGas, tx-ready wei) for one chain, read live from public RPCs.
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.
spot_price — Live Chainlink on-chain spot price for an asset (latestRoundData, with round metadata).
token_safety — Heuristic token safety check: follows the proxy and scans the bytecode that actually runs, plus ownership and transfer restrictions.
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.
