feat: add AgentRadar action provider

[Bichev]

Description

Adds an AgentRadar action provider so any AgentKit agent can check the on-chain trust of a counterparty before interacting with or paying it.

AgentRadar returns a composite trust score (0-100) built from ERC-8004 reputation, a scam-wallet database, and static analysis. This complements the existing erc8004 and x402 providers: ERC-8004 exposes raw identity/reputation, and this provider turns the broader signal set into a single verdict an agent can act on right before a payment.

Two actions, both network-agnostic, read-only, and requiring no API key:

Action	Description
verify_agent	Composite score (0-100) + verdict (TRUSTED/VERIFIED/CAUTION/RISKY/BLOCKED) + per-signal breakdown for an EVM address
get_trust_badge	Embeddable trust-badge SVG URL for an address

Example

import { AgentKit, agentRadarActionProvider } from "@coinbase/agentkit";

const agentkit = await AgentKit.from({
  walletProvider,
  actionProviders: [agentRadarActionProvider()],
});
// "Verify 0x036C…CF7e before I pay it" → { score, verdict, signals, ... }

Files

• src/action-providers/agentradar/ — agentRadarActionProvider.ts, schemas.ts, types.ts, constants.ts, index.ts, README.md, and tests
• Registered in src/action-providers/index.ts
• Documented in the package README.md provider table
• Changeset added (@coinbase/agentkit, minor)

Testing

Mirrors the defillama provider pattern (HTTP, no wallet). All run from typescript/agentkit:

• pnpm exec jest src/action-providers/agentradar → 7/7 pass
• pnpm run check (tsc --noEmit) → clean
• pnpm exec eslint src/action-providers/agentradar → clean
• pnpm exec prettier --check → clean

Checklist

• Followed the existing action-provider structure (defillama as reference)
• Unit tests for success, HTTP error, network error, and badge/network cases
• No new dependencies (uses zod + global fetch)
• Changeset included
• Lint, format, type-check, and tests pass locally
