DropEngine x402 Agent Services missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 19

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

invoice

invoice_preflight

Paid invoice check ($0.065 USDC on Base): UBL XML or complete PDF/image invoices up to 3 pages. Compares expected purchase fields and line items; returns evidence, amount checks and match/discrepancy/needs_review. No payment or bookkeeping action is taken.

invoice_preflight_10_pages

Paid invoice OCR ($0.13 USDC on Base): process complete PDF/image invoices up to 10 pages. Oversized PDFs are rejected before OCR.

invoice_preflight_50_pages

Paid invoice OCR ($0.475 USDC on Base): process complete PDF/image invoices up to 50 pages. Oversized PDFs are rejected before OCR.

invoice_preflight_quote

FREE, no wallet or document upload: choose the lowest priced Invoice Preflight tool from document type, PDF page count, and optional byte size. Call this before a paid invoice tool when the tier is uncertain. It does not inspect or validate the document.

scan

scan_arbitrage

Paid Arbitrage Intelligence ($0.03 USDC). Compares Binance and Coinbase public spot order books at a requested trade size and applies caller- or server-configured taker fee assumptions. Rejects stale books. Excludes transfers, inventory rebalancing, and guaranteed execution; does not place orders.

scan_content

Paid Untrusted Content Security Layer ($0.005 USDC on Base). Scan untrusted text, HTML, Markdown, email, document text, API responses, and tool outputs before your agent adds them to context, follows their instructions, or acts. Returns risk score, risk categories, recommendation, and sanitized plain text when possible. Bounded deterministic local scanning; no external LLM or provider call. Maximum 100000 characters.

analyze

analyze_whale_activity

Paid Whale Intelligence ($0.02 USDC). Summarizes large public GeckoTerminal-indexed DEX trades for a token address on a supported chain. Large-trader labels are size-based heuristics, not verified whale identities; data is not chain-wide. Wallet mode uses Helius (Solana) or Etherscan API V2 (EVM) when configured, returning recent indexed transactions only; it does not claim complete balances or whale labels.

backtest

backtest_strategy

Paid Strategy Backtest ($0.10 USDC). Tests built-in long-only spot strategies against bounded public Binance OHLCV history. Signals form at candle close and execute at the next candle open. Applies configured fees/slippage; accepts declarative parameters only and never executes user code. Historical results are not predictions.

change

check_change

Paid Change / Diff Check ($0.001 USDC). Checks normalized text on a public HTTPS page against a previous SHA-256 hash, returning a compact diff when a prior snapshot is available.

extract

extract_structured

Paid Fresh Structured Extract ($0.01 USDC). Extracts a fresh webpage into a simple agent-defined typed JSON shape, with validation and per-field provenance. Uses static page data only; never executes page JavaScript and never fabricates missing fields.

live

get_live_quote

Paid Live Product Quote ($0.01 USDC). Retrieves explicitly published product price and stock from a public HTTPS product page before an agent buys; shipping, tax and unknown values remain null. Never purchases.

mcp

mcp_server_inspect

MCP server health check ($0.01 USDC on Base): connect to any public MCP endpoint over HTTPS, confirm it is reachable, list its tool names and input-schema summaries, compare against expected tool names, and flag risky or misleading tool descriptions. Read-only: inspected tools are never called. Use it before wiring an unknown MCP server into an agent, or to verify your own deployment. Pair with check_url to pre-screen a suspicious endpoint.

package

check_package

Paid Package Safety Gate ($0.005 USDC on Base). Call before a coding agent installs, imports, or adds an unfamiliar npm dependency. Checks resolved package/version, OSV vulnerabilities and malware advisories, popular-name typosquatting, and install lifecycle scripts using static analysis only. Package code is never executed. Checks up to 10 direct dependencies when their versions can be resolved; it does not traverse transitive dependencies or assess maintainer history. Unknown coverage returns caution.

route

route_tool

Paid Agent Tool Router ($0.002 USDC on Base). Finds and ranks machine-payable MCP services and x402 HTTP endpoints before your agent chooses or pays a provider. Uses structured capability matching, hard constraints, price, observed latency/reliability, and cold-start trust confidence; no LLM call is required. Returns a recommendation only: it never invokes the selected provider or makes a second payment. Without X402_BAZAAR_DISCOVERY_URLS, results come only from this platform's local service registry and are marked degraded.

simulate

simulate_transaction

Paid Transaction Preflight ($0.02 USDC on Base). Simulates an unsigned Base transaction before an autonomous agent signs or broadcasts it. Returns RPC execution/revert status, gas estimate, known top-level method decoding, direct ERC-20 transfer/approval calldata, unlimited approval warnings, and machine-readable risk. Standard JSON-RPC does not expose full internal token state changes; do not treat calldata decoding as a complete state diff. Never send a private key or seed phrase. This tool never signs, holds keys, or broadcasts.

token

token_security_audit

Paid Token Security Audit ($0.01 USDC). Normalizes GoPlus token-security flags and public EVM RPC metadata for supported EVM tokens. Configure GOPLUS_ACCESS_TOKEN or explicitly enable the bounded public API with GOPLUS_PUBLIC_TOKEN_API_ENABLED=1; if neither is available, no payment is requested. Missing provider fields remain unknown and incomplete coverage returns caution. Reports provider findings separately from deterministic internal scoring. Does not trade or guarantee token safety.

url

check_url

Paid Agent Preflight URL check ($0.005 USDC on Base). Call before an agent opens, follows, downloads from, or trusts an unknown URL. Performs deterministic checks, safely inspects HTTPS redirects without loading page content, blocks localhost/private addresses, and optionally queries Google Web Risk when configured. No LLM is used. A clean result is not a guarantee of safety.

verify

verify_claim

Paid Freshness / Claim Verifier ($0.02 USDC). Checks a factual claim against fresh web search evidence and returns supported/contradicted/mixed/insufficient/stale with sources. Requires TAVILY_API_KEY. If the key is missing, returns a provider-unavailable error before requesting payment. Claim text is sent to the configured search provider.

wallet

check_wallet

Paid Wallet Risk Check ($0.02 USDC on Base). Call before an agent sends funds to, accepts value from, grants an approval to, or interacts with an unfamiliar address. Checks whether the address is a wallet or contract and reads basic on-chain metadata. Sanctions, scam, drainer, mixer, and malicious-address intelligence are unknown unless a trusted provider is configured; without one, the result is cautious and low-confidence, not a safety certification. Never send private keys or seed phrases.

DropEngine x402 Agent Services — questions

Answers built from our own checks of this server.

What can DropEngine x402 Agent Services do?

It exposes 19 tools, read directly from the server on our last check. Among them: analyze_whale_activity, backtest_strategy, check_change, check_package, check_url, check_wallet and 13 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 DropEngine x402 Agent Services mostly used for?

Its tools cluster around invoice and scan. 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 DropEngine x402 Agent Services working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 346 ms. The bar chart above shows every period we have measured.

Did DropEngine x402 Agent Services ever remove tools?

Yes. estimate_trade_execution is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Is DropEngine x402 Agent Services still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect DropEngine x402 Agent Services?

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

Does DropEngine x402 Agent Services need an API key?

No. DropEngine x402 Agent Services completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 19 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is DropEngine x402 Agent Services?

It answers our handshake in 346 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
