# AgentProof Integration Kit

## The one-line integration

**Before an autonomous system takes an economically meaningful action, call AgentProof to resolve inherited authority.**

Production endpoint:

`POST https://agentproof.hatchable.site/api/paid/resolve_transaction`

Current hosted price: **$0.01 via x402 v2 / USDC on Base**.

## Try it free first

Use the non-production sandbox with identifiers beginning with `demo:`:

`POST https://agentproof.hatchable.site/api/growth/sandbox`

The sandbox is deliberately non-authoritative, non-persistent and non-billable.

## Current protocol

- Direct authority: `agentproof.resolution/0.1`
- Recursive authority: `agentproof.resolution/0.2`
- Core invariant: **delegation may narrow inherited authority; it may never widen it**

## Best-fit customers

- agent wallets and payment layers;
- AI marketplaces;
- autonomous procurement and buying agents;
- enterprise agent platforms;
- robotics and machine commerce;
- agent infrastructure/framework vendors;
- compliance, governance and risk platforms;
- marketplaces where agents transact with unfamiliar counterparties.

## Fastest evaluation

1. Read the public example: https://agentproof.hatchable.site/api/resolution/example-chain
2. Read the policy: https://agentproof.hatchable.site/api/resolution/policy
3. Inspect OpenAPI: https://agentproof.hatchable.site/openapi.json
4. Test the free sandbox.
5. Hit the paid endpoint without a signature to inspect the live x402 challenge.
6. Integrate one pre-transaction call.
7. Add Agent Transaction Passport™ issuance after execution.

## Commercial positioning

AgentProof is the transaction-admission control plane between autonomous intent and autonomous action.

**Resolve before action. Passport after action. Outcomes improve the trust graph.**
