Blockchain IQ x402 Crypto Data

io.github.jgmale123/blockchainiq-x402-mcpv0.1.1Other

Pay-per-call crypto market data over x402 (USDC on Base). Free catalog and sample without a wallet.

The current version, v0.1.1, was published to the official MCP registry on 2026-10-02. It is distributed as blockchainiq-x402-mcp on npm, filed under Other by this index, and declares 4 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

Using Blockchain IQ x402 Crypto Data in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

Own this server? Test a description on the public screen → It is a separate check from the verdict above, so the two can differ.

That verdict was true at screening time (snapshot 2026-10-19).

Contracts can change after screening, with no version bump. The gate pins Blockchain IQ x402 Crypto Data’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Environment variables

AGENT_PRIVATE_KEY

secret

Private key of your own EVM wallet holding USDC on Base, used to pay for paid tools. Optional: without it only the free catalog and sample tools return data. Use a dedicated low-balance wallet, never a main wallet. It is read locally to sign payments and is not sent anywhere.

MAX_USDC_PER_CALL

The most, in US dollars, the server will pay for a single call. A request priced above this is refused. Must be a positive number. The dearest call is $0.25.

BLOCKCHAINIQ_BASE_URL

Base URL of the API. Only change this to test against another deployment.

BLOCKCHAINIQ_NETWORK

The one network the wallet will pay on: base (Base mainnet) or base-sepolia (testnet, only for a test deployment). Payment requests on any other network are refused.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 972,115). Verify it yourself.
