Guides

Practical guides and workflows for integrating BlockVectra APIs, managing CU consumption, and building multichain applications.

Practical guides and end-to-end workflows for using BlockVectra JSON-RPC and Data APIs across supported chains.

What the Free Plan Covers: Method Weights and Usage

Understand what the Free Plan covers based on real method weights, with task-based calculations and upgrade paths.

Daily on-chain metrics for tokenized stocks with the Data API

Query daily tokenized stock leaderboards and historical metrics with the Data API, covering fields, encoding conventions, pagination, and usage estimates.

Daily DEX OHLC and VWAP for a token, with exact fractions

Query daily DEX OHLC prices and VWAP from the Data API, handle exact rational fractions in TypeScript and Python, and backfill historical data efficiently.

One key, many chains: switching an example to another chain

The same API key works on every supported chain. Learn how URLs are structured, how to discover chains programmatically, and how balances and limits pool.

What is not billed: error codes and billing rules

A detailed breakdown of billing rules across HTTP status codes, JSON-RPC errors, and the Data API, with recommended actions for developers.

Connect an AI agent to BlockVectra: llms.txt, OpenAPI and public JSON

Integration guide for AI agents and LLM tools: discover capabilities with llms.txt and OpenAPI specs, then check chains and call BlockVectra APIs.

Recent node data vs indexed history: when to use eth_getLogs and when to use the transfers API

Compare the JSON-RPC eth_getLogs method with the Data API transfers endpoints: block ranges, pagination, coverage, finality limits, and which fits a task.

eth_getLogs block range limits and chunked queries

Understand per-chain block range limits for eth_getLogs, resolve the block range too large error, and query wide intervals in chunks.

Per-method pricing: reading CU and price per million calls

Understand BlockVectra's CU metering, method weight resolution rules, price per million calls formula, and how to estimate per-cycle usage and costs.

Build a wallet assets page with the Data API: balances, transfers and token info

Build a wallet assets page with the Data API. Query address balances, transfers, and batch token metadata with cursor pagination and decimals scaling.

Transaction traces: debug_traceTransaction and the Data API trace endpoints

Reconstruct execution call trees for a transaction: the JSON-RPC debug_traceTransaction method with its allowed tracers and guards, and the Data API getTransactionTrace and getBlockTraces endpoints with their finality limits.
