# api.bitfence.ai

Bitfence is a pay-per-call risk context API operating on the Base network. It serves agents and applications that need on-demand, single-shot risk assessments for specific resources or entities and are equipped to handle micropayments via EIP-3009. It is a narrow, focused service with one callable skill and no batch or streaming capabilities.

## When to use this host

Use api.bitfence.ai when an agent needs a one-off contextual risk assessment for a specific resource or entity and can execute a micropayment of 0.005 USDC on Base via EIP-3009. Do not use this host for bulk risk scoring, streaming risk feeds, or high-frequency repeated lookups where per-call costs would accumulate significantly. It is also not suitable for agents that lack EIP-3009 payment capability or are not operating on the Base network. For broader threat intelligence, on-chain analytics, or wallet/address scoring at scale, look for alternative providers with batch APIs or subscription-based pricing.
