Not supported: Provides read-only blockchain data access for Ethereum and EVM chains. Does not custody assets, sign transactions, or submit transactions to the network. Gas prices are recommendations only and do not guarantee transaction confirmation times.

Jentic publishes the only available OpenAPI document for Pillar Blockchain Explorer API, keeping it validated and agent-ready.

The Pillar Blockchain Explorer API (BCX API) provides programmatic access to Ethereum and EVM-compatible blockchain data through a REST interface. It exposes transaction history queries, real-time gas price recommendations across multiple speed tiers, and aggregated gas statistics for building wallet applications, transaction monitoring dashboards, and blockchain analytics tools. The API is designed to support the Pillar smart contract wallet ecosystem but is available for general blockchain data access. Jentic publishes enriched documentation for this API, making it discoverable and accessible to AI agents that need reliable blockchain data without operating their own nodes.

Use Cases

Patterns agents use Pillar Blockchain Explorer API API for, with concrete tasks.

★ Wallet Transaction History Display

Build a crypto wallet interface that displays complete transaction history for user addresses. The /txHistory endpoint returns detailed transaction data including hash, block number, from/to addresses, value, gas details, confirmation count, and transaction status. Wallet developers can show users their full transaction activity across ETH and ERC-20 tokens with timestamp information, making it easy to track spending, receipts, and pending transactions without running a full Ethereum node.

Query the transaction history endpoint with the user's address and asset type, then format the returned transaction array with hash, timestamp, value, and confirmation status for display in the wallet interface.

Dynamic Gas Price Optimization

Implement intelligent gas price selection for Ethereum transactions by querying real-time gas station data. The /gasStation endpoint provides four gas price tiers (safeLow, standard, fast, fastest) along with current block time and block number, enabling applications to offer users cost-versus-speed trade-offs. DeFi applications, wallets, and automated trading bots can dynamically adjust gas prices based on network conditions, helping users save on fees during low-congestion periods or prioritize speed during time-sensitive operations.

Call the gas station endpoint to retrieve current gas price recommendations, compare the four tiers against the user's urgency requirement, and select the appropriate gas price for transaction submission.

Blockchain Analytics Dashboard

Create blockchain monitoring and analytics dashboards that track network conditions and transaction patterns. The /gasInfo endpoint provides aggregate gas data including average gas price and standard deviation, while transaction history queries enable analysis of address activity patterns. Analytics platforms can monitor gas price trends over time, identify high-activity addresses, track smart contract interactions, and provide insights into network congestion and usage patterns for traders, researchers, and protocol developers.

Aggregate data from gasInfo and txHistory endpoints to calculate network utilization metrics, gas price trends, and transaction volume statistics for visualization in the analytics dashboard.

Transaction Status Monitoring

Build reliable transaction monitoring systems that track transaction confirmation status and automatically notify users or trigger workflows when transactions are confirmed. By querying transaction history with address and transaction hash, applications can monitor the nbConfirmations field and status to determine when transactions have achieved sufficient finality. This is essential for payment processors, DeFi protocols, NFT marketplaces, and any application that needs to wait for on-chain confirmation before proceeding with business logic.

Poll the transaction history endpoint for the specific transaction hash, check the nbConfirmations count against the required threshold (e.g., 12 confirmations), and trigger the confirmation callback when the threshold is met.

FAQs

Specific to using Pillar Blockchain Explorer API API through Jentic.

What is the Pillar Blockchain Explorer API?

The Pillar Blockchain Explorer API is a REST interface for accessing Ethereum and EVM-compatible blockchain data, including transaction history, gas prices, and network statistics. It provides three main endpoints for transaction queries, real-time gas recommendations, and aggregated gas data.

How do I authenticate with the Pillar API?

The Pillar Blockchain Explorer API uses API key authentication. You configure the API URL and authentication when initializing the SDK or making direct HTTP requests. Contact Pillar Project or check their developer documentation for API key provisioning.

What blockchain networks does the Pillar API support?

The Pillar Blockchain Explorer API supports Ethereum mainnet and EVM-compatible chains. It can query transaction history for native ETH and ERC-20 tokens, making it suitable for multi-chain wallet applications built on Ethereum-compatible networks.

What gas price tiers are available from the gas station endpoint?

The gas station endpoint provides four gas price tiers: safeLow (most economical), standard (average speed), fast (quicker confirmation), and fastest (priority confirmation). Each tier is returned in Gwei along with the current block time and block number.

Can I use this API to submit transactions to the blockchain?

The Pillar Blockchain Explorer API is designed for reading blockchain data, not submitting transactions. It provides transaction history queries and gas price recommendations, but transaction signing and submission would typically be handled by wallet SDKs or web3 libraries that interact directly with Ethereum nodes.

How is this API different from running my own Ethereum node?

The Pillar Blockchain Explorer API provides a hosted REST interface to blockchain data, eliminating the need to run, maintain, and sync your own Ethereum node. It offers formatted, easy-to-consume endpoints for common wallet and application needs like transaction history and gas prices, whereas a full node requires more technical infrastructure and provides raw blockchain access.
