How this service works
Compare transaction fees across Layer 2 networks
Output
Returns an array of Layer 2 network objects, each with the network name, average transaction fee (in USD or ETH), transactions per second (TPS), and a savings percentage compared to Ethereum L1.
Example use cases
Example prompt
“Can you show me a comparison of transaction fees across the major Layer 2 networks right now, including how much I'd save versus transacting on Ethereum mainnet?”
Technical details
Endpoint
GEThttps://api.web3identity.com/api/l2/feesWhen to prefer
Use this endpoint when an agent needs a real-time, multi-network comparison of L2 transaction costs and throughput in a single call, rather than querying each L2 individually. Ideal for helping users decide which Layer 2 to use for a transaction, or for DeFi routing logic that optimizes for fee minimization.
Side effects
- Upstream L2 data unavailable — empty or partial array returned
- Payment not processed — 402 response requiring x402 payment of $0.01 USDC
- Rate limiting — too many requests in a short window
- Network timeout if L2 data sources are slow to respond
