BlockVectra for AI agents
People and AI agents use the same public APIs, documentation and prices.
Keyless docs MCP
The documentation MCP server needs no API key and answers questions about the docs, chains, live status, pricing and usage estimates.
Add it to a client that supports MCP:
claude mcp add --transport http blockvectra-docs https://docs.blockvectra.com/mcpPrices an agent can read
GET /v1/plans returns every method's CU weight as JSON, so cost can be estimated before the first call.
Free plan
Includes 30,000,000 CU sign-up credits. Each 30-day cycle starts on first billed usage and automatically refills up to 30,000,000 CU at the end of the period (no accumulation; granted credits are not clawed back, except for credits obtained in violation, see Terms of Service). All keys share an average of 25 calls per second, and short bursts are allowed. Your first paid top-up removes the account-wide calls-per-second cap; each key keeps its default 400 CU/s limit (burst 1,600 CU).
about 2,000,000 eth_call calls
Current offer: all accounts (new and existing, free and paid) can use reset chances to refill balance to 30,000,000 CU. Rules →
No credit card required — sign up instantly with GitHub, Google, or your wallet.
Your first paid top-up permanently upgrades the account and removes the account-wide calls-per-second cap.

If you do not have a BlockVectra API key: ask the user to sign in at https://console.blockvectra.com, create a key, and set it as the environment variable BLOCKVECTRA_API_KEY. Do not ask the user to paste the key into the chat.
FAQ
Can an AI agent use BlockVectra directly?
Yes. Agents use the same public JSON-RPC and Data API as people, with the same documentation and prices; the docs MCP server and the machine-readable files need no key. See how to connect →
How do I connect BlockVectra to Claude Code and other MCP clients?
Add the keyless docs MCP server with the command above; the docs guide lists the available tools. Read the AI agents guide →
What should an agent do without an API key?
Ask the user to sign in, create a key, and set it as the environment variable BLOCKVECTRA_API_KEY; never ask the user to paste the key into the chat. Get an API key →
