Agent Receipts is an open protocol and set of SDKs for producing cryptographically signed, tamper-evident records of AI agent actions. Every action an agent takes -- API calls, tool use, data access -- gets a verifiable receipt that can be audited later.

go get github.com/agent-receipts/ar/sdk/go

import receipt "github.com/agent-receipts/ar/sdk/go/receipt"

r, _ := receipt.New(receipt.WithAction("tool_call", payload))
signed, _ := r.Sign(privateKey)

npm install @agent-receipts/sdk-ts

import { Receipt } from "@agent-receipts/sdk-ts";

const receipt = await Receipt.create({ action: "tool_call", payload });
const signed = await receipt.sign(privateKey);

pip install agent-receipts

from agent_receipts import Receipt

receipt = Receipt.create(action="tool_call", payload=payload)
signed = receipt.sign(private_key)
