BlockVectra

Multi-chain RPC and blockchain data APIs

Blockchain JSON-RPC and Data API, pay as you go from $0.01 in USDC / USDT / USDG — no subscription or card required. Every method has a public price. AI agents can sign up with a wallet signature over HTTP.

Two ways in

JSON-RPC

Standard EVM JSON-RPC methods (available methods vary by chain; debug_trace methods are open on select chains only). Pass your API key in the path or an x-api-key header. Each method is metered by its own CU weight.

Data API

REST endpoints for blocks, transactions (with logs and traces), address activity and balances, token transfers and holders, token metadata, NFTs, DEX trades and daily prices, tokenized stocks, and data freshness. Available datasets and history vary by chain.

Why BlockVectra

One key for nodes and data

The same API key calls JSON-RPC on every supported chain and the Data API where a chain offers it; balance and rate limits are pooled across chains.

Prices you can see

Every method has a public CU weight and price per million calls. Rejected requests are not billed, and the Data API bills only successful responses.

Data you can check

Every successful chain-scoped response states as_of_block, finalized_block, coverage and refreshed_at; block-scoped queries beyond as_of_block return 409.
