market_npm_package_risk

One keyless read of the public npm registry for a package: does it ship an install-time script (the way malicious packages run code at install), is the released version deprecated, how old is the last publish, how many maintainers and dependencies, is there signed provenance, and what flags come out of those facts.

chain_block_series

Height, timestamp, transaction count, gas used and base fee for up to 25 consecutive blocks — the series itself, so a caller can plot throughput or fee pressure instead of taking our word for the average.

Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/client-version?chain=base.

Byte-identical to GET /chain/contract-diff?chain=base&address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&other=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.

Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/fee-data?chain=base.

chain_fee_history

eth_feeHistory over a bounded window: base fee at every block plus the 25/50/75 priority-fee percentiles.

Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/fee-history?chain=base&blocks=20.

chain_logs

eth_getLogs over a bounded window (max 1000 blocks) with an address and/or first topic — transfers and events without running an indexer. Refuses an unfiltered scan. Walks the window in chunks because a free node refuses a big one on response size, and reports any range no node would serve instead of failing a settled call. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/logs?chain=base&address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef&fromBlock=5000&toBlock=5999.

chain_network_id

eth_chainId versus net_version for one chain. A mismatch is how a wallet ends up signing Base transactions for Mainnet, so this is a two-call safety check, not trivia. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/network-id?chain=base.

chain_nft_approved

chain_nft_owner_at

ownerOf(id) read at a chosen block and again at the head: previous holder, current holder, and whether it moved — the ownership history a sale-attribution or stolen-collection check needs. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/nft-owner-at?chain=base&token=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&tokenId=1&block=latest.

Byte-identical to GET /chain/permit-ready?chain=base&token=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&owner=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.

chain_proxy_check

eth_syncing plus the head: a public node that is quietly 300 blocks behind answers every other question with stale data, and nothing else in a response tells you that. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/sync-status?chain=base.

Crypto Bot Audit + Market Data (x402 paid) — questions

Answers built from our own checks of this server.

What can Crypto Bot Audit + Market Data (x402 paid) do?

It exposes 146 tools, read directly from the server on our last check. Among them: audit_bot_code, chain_1155_balance, chain_1155_batch, chain_1155_check, chain_1155_uri, chain_allowance and 140 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Crypto Bot Audit + Market Data (x402 paid) mostly used for?

Its tools cluster around market and chain. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Crypto Bot Audit + Market Data (x402 paid) working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 138 ms. The bar chart above shows every period we have measured.

The registry lists Crypto Bot Audit + Market Data (x402 paid) as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Crypto Bot Audit + Market Data (x402 paid)?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Crypto Bot Audit + Market Data (x402 paid) need an API key?

No. Crypto Bot Audit + Market Data (x402 paid) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 146 of them are readable on this page. This is what we observed, not what the docs claim.
