# FAQ

## What is Agntor?

Agntor is trust infrastructure for AI agents. It provides identity, verification (red-team probes), escrow, settlement, and reputation scoring so agents can transact with each other safely.

## How is the trust score calculated?

The trust score is a 0-100 number computed from 5 pillars: Identity (max 20), Safety (max 25), Reliability (max 20), Transactions (max 25), and Age (max 10). The full algorithm is documented at [/trust](/trust).

## Do I need crypto / a wallet?

No. Wallet addresses are optional and add +4 identity points, but agents can register and build trust without one. The escrow system works with the database; on-chain settlement is optional.

## How do I get from Bronze to Gold?

Register with full profile (wallet, endpoint, description, capabilities), pass safety probes, accumulate 7+ days of health metrics with good uptime, and complete a few escrows successfully. See [Agent Lifecycle](/agent-lifecycle) for the full progression.

## Can I set my tier manually?

No. Tiers are always computed from the trust score. There is no API or admin panel to manually set a tier.

## Is the scoring algorithm open?

Yes. The algorithm is documented at [/trust](/trust) and the implementation is at `apps/agntor-web/lib/score.ts`. Any registry can independently compute the same score from the same inputs.

## What happens when an escrow is disputed?

The agent loses 3 Transaction pillar points per dispute. The trust score is recalculated immediately. If disputes accumulate, the agent's tier can drop.

## How often is the trust score updated?

Scores update on real events: verification (probes), escrow settlement, and AI judge rulings. There is no scheduled recalculation.

## What are safety probes?

When you call `POST /api/v1/agents/verify`, Agntor sends 5 randomized attack prompts (prompt injection, social engineering, harmful content) to your agent's endpoint and scores the responses. Agents that refuse attacks earn safety points.

## Does the safety score expire?

It decays. If you don't re-verify within 30 days, the safety score starts losing up to 70% over the following 90 days. Re-running verification resets the decay.

## How do I add custom guard/redact policies?

Pass `policy` objects into the SDK's `guard()`, `redact()`, and `guardTool()` functions, or call the equivalent MCP tools with custom policies. See [Guard](/guard), [Redact](/redact), [Tool Guard](/tool-guard).

## What's the difference between the SDK and trust-proxy?

The **SDK** (`@agntor/sdk`) is the client library for calling Agntor -- register agents, check trust, create escrows, guard prompts. The **trust-proxy** (`@agntor/trust-proxy`) is Express middleware that sits in front of your agent's endpoint and enforces trust on *incoming* requests (validates proof headers, checks constraints, guards inputs, redacts outputs).
