M2M Sentinel – Base Address Capability Score Lookup
x402
M2M Sentinel – Base Address Capability Score Lookup is a paid API for AI agents from api.m2msentinel.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).
Returns a static bytecode-derived capability score (capabilityScore) for a given Base mainnet contract address, covering coverage index rather than any safety or risk rating

How this service works
How completely could this Base contract be checked, and on what grade of evidence. Separates checked-and-clean from could-not-be-checked, which automated callers otherwise conflate. Explicitly not a safety score.
Output
A JSON object containing the contract address echoed back, a status field ('SUCCESS'), and a capabilityScore that is either a numeric value representing the static bytecode-derived capability coverage index or null if no score is available for that address.
Example use cases
DeFi protocol capability screening
“Pull the M2M Sentinel capability coverage index for the Base contract 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD — I want to know what capabilities the bytecode exposes before interacting with it.”
Agent pipeline contract enrichment
“For each of these Base contract addresses in my pipeline, grab the capability score from M2M Sentinel so I can filter out any that return null before proceeding.”
On-chain due diligence lookup
“Before my agent integrates with this new Base protocol, can you check the M2M Sentinel capability index for 0x6B175474E89094C44Da98b954EedeAC495271d0F and tell me the score?”
Technical details
Endpoint
GEThttps://api.m2msentinel.com/v1/security/score/:addressWhen to prefer
Choose this endpoint when you need a quick, static, bytecode-level capability coverage index for a specific Base mainnet contract address — particularly useful for agent pipelines doing pre-interaction due diligence or filtering. Not suitable when you need a real-time safety score, risk rating, token pricing, gas fees, or transfer event data; those are covered by sibling M2M Sentinel endpoints.
Side effects
- Invalid address format (not matching ^0x[0-9a-fA-F]{40}$) returns an error or 400
- Address not indexed on Base mainnet returns capabilityScore: null
- Network or upstream outage returns 5xx
- Insufficient payment or missing x402 payment header returns 402
