• gas_nowA

  MCPFax On-Chain ToolkitA

  Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon — in wei and gwei, plus what a plain 21,000-gas transfer would cost in the native token, which is the number you actually budget with. Pass several chains comma-separated to compare where to execute. Call this immediately before sending a transaction: gas moves every block, so the answer is good for seconds, not minutes. Costs $0.005 USDC per call via x402 on Base.

• get_gas_pricesA

  Vibe SpringsA

  Real-time gas price oracle for Base, Ethereum, Arbitrum, and Optimism. Returns slow/standard/fast fee tiers, estimated costs for common operations, and network congestion status. [PAID: $0.001 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

• get_bridge_quoteA

  Crank ProtocolB

  Cross-chain bridge quote via deBridge DLN (FREE read, no execution). Quote moving ``amount`` (source-token base units) of ``src_token`` on ``src_chain`` into ``dst_token`` on ``dst_chain``. Supported chains: ethereum, arbitrum, base, optimism, polygon, bnb, avalanche, linea, solana (one side must be solana). Returns estimated destination amount, per-leg USD values, and DLN protocol costs. Use before bridge_in / bridge_out. Nothing is charged and no order is created.

• write_wallet_upgrade_veloA

  Arcadia FinanceA

  Upgrade VELO held in a wallet on Optimism to the new AERO on Base: ordered unsigned wallet transactions from owner_address, an approve when the allowance is short, then depositLiquid on the Velodrome migration with the Hyperlane fee as value. 0.044 new AERO per VELO arrives at the same address on Base once the message lands. VELO inside an Arcadia account must be withdrawn to the wallet first (write_account_withdraw). VELO stays usable, so this is optional. Optimism (chain_id 10) only. 'upgrade unavailable' names the contract's reason: not_open (with the opening time), paused, budget_exhausted, recipient_not_deployed (a contract wallet with no code on Base).

• chain_balanceA

  Wicked MCPA

  [Trading Data API] Native-token balance (ETH/POL) for any address or ENS name on Ethereum, Base, Arbitrum, Optimism or Polygon. Live from the chain over redundant RPCs — wei plus formatted units. **Example:** `/v1/chain-balance?address=vitalik.eth&chain=ethereum` Use when you need the native-token balance (ETH/POL) of an address or ENS name on Ethereum, Base, Arbitrum, Optimism or Polygon. Not for token balances (use chain_token_balance) or a full holdings view (use wallet_portfolio). Behavior: read-only. Priced via x402 (USDC on Base) or free with WICKEDAPI_API_KEY; with neither, you get HTTP 402 with the decoded price in payment_required (a price quote, not a failure).

• optimism_native_balancesA

  Bitquery: Crypto & Blockchain DataA

  NATIVE COIN BALANCE of up to 50 Optimism (op, OP, OP Mainnet, L2) addresses: each address's current ETH balance (the coin that pays gas) - for filtering a set of wallets down to the funded ones, e.g. an airdrop cohort. NOT a token's holders → use optimism_token_holders. NOT one address's transfer history → use optimism_address_flow_summary. Pass the addresses separated by "|" (0x..) - up to 50; addresses after the 50th distinct one are ignored (compare Addresses_Requested with Addresses_Used), so split a longer list into several calls. WINDOW: only balances UPDATED within the last `since_days` days (default 2) are read, so an address that has not moved its native coin in that window returns NO row. Use the same window you searched for activity - e.g. the window of optimism_token_senders - because an active wallet's balance is always fresh there; a wider window costs more for no gain on active wallets. Native_Balance is in ETH (18 decimals); Native_Balance_Raw is the exact integer amount (wei); Balance_As_Of is when that balance was last updated. To identify the addresses, pass them to labels_for_addresses. Each row: Address, Native_Balance, Native_Balance_Raw, Balance_As_Of, Addresses_Requested, Addresses_Used.

• agent_wallet_snapshotA

  Agent Margin RouterA

  One-call wallet overview for autonomous agents: native balance, ERC-20 balances (default stablecoins + WETH, or any contracts you pass), current gas price, tx count, contract check and USD values incl. total – bundles what would otherwise be 5+ RPC calls. Base, Ethereum, BSC, Polygon, Arbitrum, Optimism. Pay per call with USDC or USDT on Base via x402. 3 free calls per wallet.

  ChainRayB

  Get a cross-chain market snapshot: ETH price, gas costs, and DeFi TVL across Base, Ethereum, Arbitrum, and Optimism in one call. Use for a fixed broad snapshot of major market, gas, and TVL signals. It is not a chain health verdict, token price lookup, or custom chain comparison; use chain.health, token.price, or chain.compare for those questions.

• list_chainsA

  Ophis MCPA

  List configured EVM orderbook chains, split into `tradeable` (orderbook URL configured; only route get_quote/build_order to these) and `paused` (no configured orderbook URL, so those tools reject the chain). This is configuration, not a live health or liquidity check. The standalone app's externally funded NEAR networks are not orderbook chains. Each tradeable chain includes its orderbook host, GPv2Settlement contract (Optimism, Unichain, Robinhood Chain, and Arc are non-canonical), and canonical Ophis fee config. No input.

• optimism_tx_eventsA

  Bitquery: Crypto & Blockchain DataA

  ALL EVENT LOGS in one or more Optimism (op, OP, OP Mainnet, L2) transactions, including decoded arguments plus raw topics and data. Use after optimism_find_events identifies a transaction, or whenever a tx receipt's complete event payload is needed. NOT the value moved in a transaction → use optimism_tx_transfers. Accepts up to 50 transaction hashes separated by "|". `Parsed=0` means no ABI matched: Event, Signature and Arguments can then be empty, but Topic0, Topics and Data remain usable. Arguments are named objects with Name, Type, string Value and Indexed; integer values are decimal strings to avoid JSON-number precision loss; use raw Topics/Data for values wider than the decoded numeric fields. Argument names come from one known ABI for the Signature and can be another contract's wording - Topics and Data are the log's own. By default, reverted call-frame logs, removed logs and failed transactions are excluded; set only_successful=0 to inspect them with the returned status fields.

• optimism_tx_transfersA

  Bitquery: Crypto & Blockchain DataA

  All token & native transfers inside ONE OR SEVERAL Optimism (op, OP, OP Mainnet, L2) transactions (sender → receiver, currency, amount, invoked method). Entry point for tracing when you have a tx hash — pass several hashes separated by "|" to inspect a batch in one call (rows are grouped per transaction, largest amount first within each). For an address's flow over time use optimism_transfers_out / optimism_transfers_in. To identify the addresses, pass them to labels_for_addresses. NOT the event logs of a transaction → use optimism_tx_events. FRESHNESS: transfers reach this data some minutes after the trade tools see a swap, so a hash that trader_trades or tx_trades already shows can return NO rows here yet - that is lag, not a missing transaction: retry in a few minutes. A transaction's own transfer is TOP-LEVEL, not internal, and is always included. Internal = 1 marks a transfer moved by contract code deeper inside a transaction; those are left out unless you pass include_internal=1.

• swap_routeA

  ISHOB Knowledge ArchiveB

  Best DEX swap route and quote on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Chain via the KyberSwap aggregator (400+ liquidity sources, split routes): output amount, slippage-protected minimum, USD value change, gas, hops.

• gasA

  FreeTier Agent APIA

  1 free call per caller, then $0.0015 USDC via x402 (paid in-band: params._meta["x402/payment"]). Gas price (5 EVM chains): Live gas prices across 5 EVM chains in one call (Ethereum, Base, Arbitrum, Optimism, Polygon): gas price in gwei, latest block, and the cost of an ETH transfer, an ERC-20/USDC transfer and a swap in native coin and USD, plus a ranking of which chain is cheapest right now. Public RPC nodes with failover; no keys. When to use: Use gas to pick the cheapest EVM chain right now or to price a transfer/swap on Ethereum, Base, Arbitrum, Optimism or Polygon in one call. Use base-gas for Base only.

• chain_portfolioA

  x402 Agent HubB

  One call returns an address's native coin, USDC and USDT balances on Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and Avalanche (or a 'chains' subset), plus a total stablecoin USD figure, instead of 21 separate reads. Chains whose RPC fails are listed in chainsFailed. You only pay for successful reads: invalid input, not-found and upstream errors cancel settlement. ($0.005 USDC on Base)
