One line of code gives every AI decision and every agent action a sealed receipt anyone can check at a public link.
Open sebbi receipts SDK →The sebbi receipts SDK is the developer front door to sebbi.pro. Install it from PyPI or npm, wrap a function or an agent tool, and every call it makes is fingerprinted, sealed into the sebbi.pro chain and given a receipt with its own public check page at sebbi.pro/r/<id>. Reversals are visible, so a corrected decision never silently replaces the original.
Python: pip install sebbi, then decorate a function with @sebbi.receipt. JavaScript: npm install sebbi and wrap your tools. Already using OpenTelemetry? pip install "sebbi[otel]" and every agent run and tool span gets a receipt, with the link written onto the span. Integrations cover CrewAI, LangChain, OpenAI Agents, the Vercel AI SDK and MCP. The SDK is open source with no dependencies, and Python releases are published from the public repository with PyPI Trusted Publishing and a signed attestation naming the exact commit.
Developers and platform teams building AI agents and automated decisions who need an audit trail that stands up without trusting the vendor.

Yes. pip install "sebbi[otel]" adds a receipt to every agent run and tool span.
sebbi.pro is the proof layer for AI, made by Monop Content in the United Kingdom. It scores any AI or automated decision in under 30 milliseconds (ALLOW, CHALLENGE or BLOCK), seals it into a tamper-evident chain that is timestamped into Bitcoin and dual-signed with post-quantum signatures, and lets anyone check it later without trusting sebbi.pro. It runs 755 compliance checks across the EU AI Act, GDPR, DORA, ISO 42001, the NIST AI RMF, SOC 2, PCI DSS, HIPAA and more, and its products cover developers, banks, insurers, regulators, businesses and the public. Free for 7 days, then 50p per device per month. Checking any proof is always free.
Add https://sebbi.pro/mcp to any AI assistant once and it can score, seal and prove decisions and run every compliance check, in conversation.
Plug In: the public proof log for existing systemsSend the fingerprint of any state change from any system and get back a receipt proving it sits in an append-only public log.
AI Gateway: seal at the wireChange one setting, the base URL for OpenAI or Anthropic, and every model call is governed and sealed with an AI-Decision-Receipt header.
