How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object with the Base network identifier (eip155:8453), product name, and an assessment object containing a list of risk flags, a risk_level string (e.g. 'low'), and a numeric risk_score. May also include activity, identity, and provenance sub-objects.
Example use cases
Example prompt
“Can you check the DEX market risk for this Base token contract 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — I want to know its risk score and any red flags before I trade it?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/base/dex-market-monitorWhen to prefer
Use this endpoint when you need a structured, machine-readable risk assessment of a specific token contract on the Base network before executing a DEX trade or approving a token. Prefer this over generic blockchain explorers when you need a normalized risk_score and flags rather than raw on-chain data.
Side effects
- Missing or malformed token address (not matching ^0x[a-fA-F0-9]{40}$) returns a validation error
- Token contract not found or not listed on any Base DEX pair may return empty activity data
- Payment not included or insufficient USDC ($0.005) results in 402 Payment Required
- Network connectivity issues to Base RPC or DEX data sources may cause timeout or 503
