Output

Example use cases
Example prompt
“What's the reputation score for the onchain AI agent at Base address 0x1234abcd...? I want to know how trustworthy it is before I interact with it.”
Technical details
Endpoint
GEThttps://avisradar-production.up.railway.app/api/agent/score/:addressWhen to prefer
Use this endpoint when you need to evaluate the trustworthiness or track record of a specific onchain AI agent deployed on Base before interacting with or delegating to it. Especially useful when the agent participates in x402 payment flows or is registered in the ERC-8004 ReputationRegistry.
Side effects
- Invalid or malformed Base address returns 400 error
- Address not found in any registry returns score of 0 or null
- Network or Railway deployment downtime returns 503
- Address is an EOA wallet rather than an agent contract — may return low or no data
- Rate limiting if called too frequently without payment
