Blast Chain Status & Native Yield Data
x402
Blast Chain Status & Native Yield Data is a paid API for AI agents from api.chainmarket-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).
Returns current block status, gas metrics, and native yield data (USDB and WETH) for the Blast L2 blockchain

How this service works
Blast L2 native yield from the chain itself: for the rebasing USDB (stablecoin yield) and WETH (ETH staking yield) predeploy contracts, total supply and share price — the cumulative native-yield multiplier since launch (e.g. 1.126 = 12.6% earned) — plus latest/safe/finalized blocks, finality lag, gas price and block time. Blast Gold / DApp points are allocated off-chain by Blast and have no public API, so they are not reported.
Output
A JSON object containing head, safe, and finalized block metadata (timestamp, number, gas used, gas limit, base fee in Gwei, transaction count), chain info (chain name, chainId, RPC source, checked-at timestamp), native yield data for USDB and WETH (contract address, share price, total supply, cumulative yield %), average block time in seconds, current gas price in Gwei, and lag metrics between head, safe, and finalized blocks.
Example use cases
Monitor Blast network congestion
“Check the current gas price and block utilization on Blast — is the network congested right now?”
Track Blast native yield for DeFi portfolio
“What's the current USDB and WETH native yield share price on Blast, and how much cumulative yield has each accrued since inception?”
Verify Blast block finality lag
“How many blocks and seconds behind is the finalized block compared to the head block on the Blast chain right now?”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/blast-gold-points?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Blast L2 chain health, gas metrics, or native yield data (USDB/WETH) without setting up your own RPC connection. Ideal for AI agents monitoring Blast DeFi positions, gas costs, or yield-bearing assets. Prefer this over generic block explorers when you need structured JSON output with native yield details in a single pay-per-call, no-signup call.
Side effects
- RPC node unreachable — upstream Blast RPC may be down
- Stale data — if the Blast chain experiences downtime, checkedAt timestamp may lag
- Payment failure — if x402 payment is not processed, call is not charged and data is not returned
- Malformed response if Blast undergoes a hard fork or block structure change
