Layer 1 Network Stats — Real-Time Gas, TPS & Congestion

Track real-time network statistics for major L1 blockchains: Ethereum, Bitcoin, Solana, Avalanche, Polygon.

No API keys required. No proxies. Uses only public endpoints.

What You Get

For each tracked chain:

Field	Description
chain_name	Chain identifier
block_height	Latest confirmed block / slot
avg_block_time_s	Average block time in seconds
avg_gas_price_gwei	Current gas price (gwei for EVM chains; sat/vB for Bitcoin)
gas_price_tier	low / medium / high / very_high
tps_estimate	Estimated transactions per second
pending_tx_count	Mempool depth (unconfirmed transactions)
network_load	idle / normal / busy / congested
fee_usd_simple_transfer	Estimated USD cost of a simple transfer at current gas price
relative_cost_score	0–100 score vs other tracked chains (100 = cheapest)
native_price_usd	Native token USD price used for fee calculation
timestamp_utc	ISO-8601 timestamp of data collection

When includeComparison is enabled, a summary record is appended:

Field	Description
cheapest_chain	Chain with lowest USD transfer fee
fastest_chain_by_tps	Chain with highest TPS
fastest_chain_by_block_time	Chain with lowest block time
most_congested_chain	Most congested chain at time of run

Input

{
  "chains": ["ethereum", "bitcoin", "solana", "avalanche", "polygon"],
  "includeComparison": true
}

Parameter	Type	Default	Description
chains	string[]	All 5 chains	Chains to track
includeComparison	boolean	true	Append cross-chain comparison record

Data Sources

Chain	Sources
Ethereum	Etherscan Gas Oracle (public), Cloudflare ETH RPC
Bitcoin	blockchain.info/stats, mempool.space/fees, blockchain.info/q/unconfirmedcount

Pricing

Event	Cost
Actor start	$0.001
Per chain tracked	$0.005

Tracking all 5 chains costs $0.026 per run.

Use Cases

• DeFi routing — pick the cheapest chain for a transaction before executing
• Arbitrage timing — detect congestion windows and time cross-chain moves
• Dashboard feeds — power real-time gas/fee widgets
• Alerting — detect when a chain transitions to congested
