Standalone examples showing how to certify AI agent outputs on the MultiversX blockchain using xProof.
xProof gives every agent action a tamper-proof audit trail anchored on-chain in ~6 seconds. Each certification records the 4W framework: Who acted, What was produced, When it happened, and Why.
| Framework | Language | Description |
|---|---|---|
| LangChain | Python | Certify every LLM call via a callback handler |
| CrewAI | Python | Certify each agent's task output in a multi-agent crew |
| LlamaIndex | Python | Certify LLM calls and query completions |
| OpenAI Agents SDK | Python | Certify tool executions and agent completions via RunHooks or TracingProcessor |
| Vercel AI SDK | TypeScript | Certify AI generations in a Next.js API route |
| AutoGen | Python | Certify messages exchanged between AutoGen agents |
| DeerFlow | Python | Certify DeerFlow agent outputs via a skill |
