How this service works

32 pay-per-call JSON APIs for AI agents. No account or API key: an unpaid POST returns HTTP 402, pay in USDC on Base with x402 v2, retry. Prices from $0.002 per call.

Output

A JSON object with a boolean 'submit' verdict (true = submit now, false = wait), EIP-1559 fee parameters (maxFeePerGas, maxPriorityFeePerGas, current and next base fee in gwei), estimated cost in ETH, gas units, and USD, current block number, CAIP-2 chain ID, a human-readable congestion summary, risk flags array, and a recheck interval in seconds if waiting is advised.

Example use cases

Optimize stablecoin settlement timing

“I'm about to send 500 USDC on Base — is now a good time to submit, or should I wait for cheaper gas? Give me the current base fee and estimated transaction cost.”

Automated DeFi bot gas gating

“Before my agent executes the on-chain swap, check the Base network congestion and tell me whether to submit immediately or hold off — use flexible urgency and USDC as the gas token.”

Urgent cross-chain bridge submission

“I need to bridge ETH from Base urgently — what are the current EIP-1559 fee recommendations and should I submit this transaction right now?”

Technical details

Endpoint

GEThttps://grokzilla.shop/api/resale/base/tx-decision?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI agent needs a real-time, actionable go/wait decision for Base blockchain transactions, including EIP-1559 fee parameter recommendations and cost estimates. Prefer this over raw RPC calls when you want a structured verdict with congestion analysis and no need to manage your own Base node. Ideal for DeFi bots, payment automation, and any agent that must time transaction submissions to minimize fees.

Side effects

HTTP 402 returned if USDC payment on Base via x402 is not attached — agent must pay and retry
Network timeout if Base RPC is slow or unavailable
Stale block data if upstream provider lags behind chain head
Missing or null fee fields if Base network data is temporarily unavailable
Invalid query parameter values for 'gas' or 'urgency' may return error or default behavior
