- Rate a call you paid foragent402.toolsTell this server whether a call you paid for delivered what it promised. Bound to the receipt: give it the settlement transaction from that call's PAYMENT-RESPONSE (or Payment-Receipt) header and a verdict of "good" or "bad", and only the wallet the ledger records as having paid for that exact call can write it - so a rating here is always a real customer about a real purchase. One verdict per settlement transaction (sending another replaces yours, it never stacks).Livechecked Evidence 2/4x402x402 Bazaar1 payer
- Onramp link (fund a wallet withagent402.toolsGenerate a single-use hosted onramp URL that lets a human fund any wallet with a card or Apple Pay - the fastest way to put real USDC into an agent's wallet. Returns the ready-to-open URL, and a fee-inclusive quote when the onramp provides one. Networks: base, ethereum, polygon, arbitrum, optimism, solana.Livechecked Evidence 2/4x402x402 Bazaar1 payer
- Chain info snapshotagent402.toolsOne-call chain state snapshot: chain id, latest block number, and current gas price (wei + gwei) for Ethereum, Base, Polygon, Arbitrum, or Optimism. Keyless multi-endpoint failover.Livechecked Evidence 2/4x402x402 Bazaar4 payers
- Resolve Uniswap V3 pool addressagent402.toolsLook up the Uniswap V3 pool address for a token pair + fee tier on Ethereum, Base, Polygon, Arbitrum, or Optimism. Pass either order (tokenA/tokenB) - the factory sorts internally. Returns 0x0…0 if no pool has been deployed for that combination yet.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- x402 market pulseagent402.toolsLive cross-provider x402 market sentiment. topProviders: the top x402 sellers ecosystem-wide, ranked by REAL on-chain activity (Agent402 included and flagged isSelf:true). Pick the lens with sort: 'usd' (revenue, default - whale-skewable), 'buyers' (distinct paying wallets - broadest adoption/reach), or 'calls' (raw volume). Every row carries all metrics plus callsPerBuyer (intensity), so revenue and actual ecosystem usage are both visible.Livechecked Evidence 2/4x402x402 Bazaar4 payers
- Token total supplyagent402.toolsThe circulating total supply of an ERC-20, read from the token contract itself rather than from an aggregator, so it is the number the chain holds at the block you asked for. Returns the raw uint256 and the same figure formatted with the token's own decimals. A contract that does not implement totalSupply answers 422 rather than a fabricated zero. EVM chains: ethereum, base, polygon, arbitrum, optimism.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Contract storage slotagent402.toolsRead one 32-byte storage slot from a contract, the raw state under whatever the source code calls it. Returns the word as hex plus three readings of the same bytes - unsigned integer, address (low 20 bytes) and boolean - because a slot is untyped on chain and only the caller knows which it meant. Useful for proxy implementation slots, paused flags and any value the ABI does not expose. EVM chains: ethereum, base, polygon, arbitrum, optimism.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- NFT metadata lookupagent402.toolsResolve the metadata for a single NFT: title, description, image URLs (original + cached CDN), attributes/traits, and the standard (ERC-721 vs ERC-1155). Useful when you have a contract+tokenId and need the display data without re-fetching the whole collection.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Token spot price (USD)agent402.toolsReturn the current USD spot price for an ERC-20 token, identified by its contract address and network. Sourced from an aggregated market price feed. Use this for portfolio-value calculations or to denominate a balance in fiat without depending on a separate market-data API.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- DEX volume by protocolagent402.toolsDecentralized exchanges ranked by 24h spot volume with 7d, 30d, 1y and all-time volume, change, the chains each trades on and sector totals. Use it when an agent needs to know where onchain spot volume is happening or how a DEX's share is moving.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Pending blockagent402.toolsThe chain's pending block: how many transactions are queued for the next block, the base fee they will pay, and the gas already used against the limit. This is the node's own view of what is about to be mined, so it answers "is the chain congested right now" without an indexer. Transaction hashes are included when the node returns them. EVM chains: ethereum, base, polygon, arbitrum, optimism.Livechecked Evidence 2/4x402x402 Bazaar3 payers
- Account nonceagent402.toolsThe transaction count of an account, which is the nonce its next transaction must carry. Ask for block "pending" to include transactions already in the mempool, which is what you want before signing; the default "latest" counts only mined transactions. Returns the count as a decimal string and as hex. EVM chains: ethereum, base, polygon, arbitrum, optimism.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Feedback tally by toolagent402.toolsWhat paying buyers said about each tool on this server: good and bad counts and the number of distinct wallets behind them, over a window you choose. Every verdict counted here was written by the wallet that paid for that specific call, one per settlement transaction, so the numbers cannot be inflated by anyone who did not buy. Counts only - no payer addresses and no review text, ever. Bad counts are published beside good ones, including ours.Livechecked Evidence 2/4x402x402 Bazaar1 payer
- ENS resolveagent402.toolsResolve an ENS name (e.g. vitalik.eth) to its Ethereum address - so an agent can turn a human-readable recipient into a payable address. Read-only on Ethereum mainnet.Livechecked Evidence 2/4x402x402 Bazaar3 payers
- OpenAPI payload validatoragent402.toolsValidate a JSON payload against the request or response schema for one operation in an OpenAPI 3.x or Swagger 2.x spec. Locate the operation by operationId or method+path; choose `part: "request"` or `part: "response"` (status defaults to the first 2xx). Deterministic subset of JSON Schema: type, required, enum, properties, items, additionalProperties:false, oneOf/anyOf/allOf, $ref-detection (not dereferenced).Livechecked Evidence 2/4x402x402 Bazaar1 payer
- Transaction statusagent402.toolsCheck the confirmation status of a transaction by hash on Base/Polygon/Arbitrum/Optimism/Ethereum/Monad/Celo/Avalanche/Sei/Arc/Robinhood Chain: success / failed / pending / not found, with block, from, to, gas used. Read-only.Livechecked Evidence 2/4x402x402 Bazaar4 payers
- ERC-20 token metadataagent402.toolsResolve an ERC-20 contract address to its on-chain metadata: symbol, decimals, name, and logo URL where available. Use this to humanize a raw contract address before showing it to a user or before computing fiat values.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Latest block numberagent402.toolsThe latest block number on Ethereum, Base, Polygon, Arbitrum or Optimism from keyless public nodes with fallback. Use it as the cheapest possible on-chain read: a liveness check for a chain, a timestamp anchor for a query, or the first paid call to prove an x402 client works end to end.Livechecked Evidence 2/4x402x402 Bazaar8 payers
- Block infoagent402.toolsHeader-level detail for one block on Ethereum, Base, Polygon, Arbitrum, or Optimism: hash, timestamp (unix + ISO), transaction count, gas used/limit, base fee. Pass a block number, 0x hex, or "latest". Keyless multi-endpoint failover.Livechecked Evidence 2/4x402x402 Bazaar8 payers
- Gas priceagent402.toolsCurrent gas price on Base, Polygon, Arbitrum, Optimism, Ethereum, Monad, Celo, Avalanche, Sei, Arc, or Robinhood Chain - for an agent budgeting a transaction: returns network, gasPriceGwei and gasPriceWei (decimal strings) from the chain's own eth_gasPrice, the node's suggested all-in price per gas unit. Multiply by the gas a transaction uses (21000 for a plain transfer) for its fee. Read-only.Livechecked Evidence 2/4x402x402 Bazaar10 payers
- Farcaster by Ethereum addressagent402.toolsReverse-lookup an Ethereum address to its Farcaster account (via verified address). Returns FID, username, display name, bio, follower/following counts, and Warpcast URL, or found=false if the address has not verified on Farcaster. Use to label wallet activity with the owner's Farcaster identity when ENS is missing.Livechecked Evidence 2/4x402x402 Bazaar1 payer
- NFT owner lookup (ERC-721agent402.toolsWho owns this NFT? Calls ownerOf(tokenId) on any ERC-721 contract on Ethereum, Base, Polygon, Arbitrum, or Optimism. Complements nft-holdings (which lists a WALLET's NFTs) - this answers by TOKEN. Keyless multi-endpoint failover.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- NFT collection metadataagent402.toolsFetch NFT collection (ERC-721 / ERC-1155) metadata by contract address on Ethereum, Base, Polygon, Arbitrum, or Optimism: name, symbol, token type, total supply, deployer, OpenSea slug + image, floor (ETH), Twitter/Discord, and verification (safelist) status. Use to label a contract address with its collection identity before pulling tokens or sales.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Wallet transaction historyagent402.toolsReturn the most recent asset transfers (incoming + outgoing) for a wallet address - native coin, ERC-20, ERC-721, ERC-1155 - already merged and sorted newest first. Each row carries the block, tx hash, counterparty, asset, and decimal value. Cap is 100 per direction; widen the window via `fromBlock` if you need deeper history.Livechecked Evidence 2/4x402x402 Bazaar1 payer
- L2 gas comparisonagent402.toolsCurrent gas snapshot across Ethereum + supported L2s (Base, Polygon, Arbitrum, Optimism), sorted cheapest-first. Returns gas price in gwei, latest block number, chain id, and an isL2 flag per chain.
