How this service works
Paid decision API for AI agents planning Base Mainnet transactions. Provide an estimated gas limit, urgency, and maximum wait window to receive EXECUTE_NOW, WAIT, or NEUTRAL from fresh public Base RPC fee data. The output includes current gas, recent percentile, short-term trend, an execution-fee estimate, confidence, and reason codes. Price: 0.005 USDC per successful request via x402 v2.
Output
Returns a JSON object with a top-level decision of EXECUTE_NOW, WAIT, or NEUTRAL, along with the current Base gas price in Gwei, the gas percentile relative to recent history, a short-term trend label (e.g. STABLE/RISING/FALLING), an estimated network fee in ETH, a confidence score (0–100), reason codes explaining the decision, data freshness in seconds, and a recommended wait time in minutes.
Example use cases
DeFi swap timing optimization
“I'm about to execute a token swap on Base with a gas limit of about 150000 — urgency is normal and I can wait up to 20 minutes. Should I fire it now or hold off until gas drops?”
High-urgency NFT mint execution
“I need to mint an NFT on Base immediately — urgency is high, gas limit is around 80000. Tell me the current gas situation and whether I should execute right now.”
Low-urgency batch payout scheduling
“I'm planning a batch payout contract call on Base with a gas limit of 500000 — I'm in no rush and can wait up to 2 hours. Is now a good time or should I wait for cheaper gas?”
Technical details
Endpoint
POSThttps://base-tx.weatherriskapi.com/v1/base/transaction-decision?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a real-time, opinionated go/no-go signal for Base Mainnet transaction submission — especially when gas cost optimization matters and the agent can tolerate a configurable delay. It is ideal for DeFi workflows, automated payouts, or any on-chain action where timing affects cost. Prefer this over manually polling eth_gasPrice when you want a pre-interpreted recommendation with trend context and confidence scoring rather than raw fee data.
Side effects
- Invalid gas limit outside 21000–30000000 range returns a 400 validation error
- Invalid urgency enum value returns a 400 bad request
- maxWaitMinutes outside 0–120 range returns a 400 error
- Base RPC node unavailability may cause 503 or degraded confidence scores
- Payment failure via x402 results in a 402 response before the decision is computed
- Stale RPC data may produce higher dataFreshnessSeconds and lower confidence
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| urgency | string | Tolerance for delay: low favors waiting when current gas is expensive; normal balances price and time; high never returns WAIT. |
| gasLimit | integer | Estimated execution gas units for the planned Base transaction. Obtain this from transaction construction or eth_estimateGas; this API does not estimate it. |
| maxWaitMinutes | integer | Maximum acceptable delay. Zero means waiting is unavailable and produces EXECUTE_NOW. |
