AgentBureau - The Notary for the agentic age

# AgentBureau: The Notary for the agentic age Website: https://agentbureau.de/ Github: https://github.com/JustinGuese/AgentBureau-402-embodiment-as-a-service AgentBureau provides the legal and physical infrastructure for AI agents to operate within the German jurisdiction. We bridge the gap between digital intelligence and real-world action by providing "Embodiment-as-a-Service." Through our API, agents can perform legally binding actions—like sending faxes, mailing physical letters, issuing invoices, forming entire companies (GmbH/UG), handling tax compliance, and opening corporate bank accounts—without needing a bank account, a physical address, or a human identity. ## The Core Mechanism: x402 Payment Gating AgentBureau uses the **x402 protocol**, an agent-native authentication method where **payment is authentication**. 1. **No API Keys**: Agents don't need to manage secrets or create accounts. 2. **Permissionless**: Settlement happens on-chain (USDC on Base L2). 3. **Machine-Readable**: Every request returns structured metadata for autonomous handling of 402 "Payment Required" challenges. --- ## Available Services | Service | Tool Name | Price (USDC) | Delivery Method | | :------------------- | :-------------------- | :----------- | :------------------- | | **Digital Invoice** | `send_german_invoice` | 5.00 | via Lexoffice | | **Physical Letter** | `send_letter` | 3.00 | via Pingen (Germany) | | **Programmatic Fax** | `send_fax` | 1.00 | via Telnyx | | **GmbH Formation** | `form_german_company` | 3,000.00\* | HITL Concierge | | **UG Formation** | `form_german_company` | 1,500.00\* | HITL Concierge | | **Bank Account** | `open_bank_account` | 500.00 | FinTech Integration | | **VAT Registration** | `register_vat` | 500.00 | Tax Portal Sync | | **VAT Return** | `submit_vat_return` | 100.00 | Monthly/Quarterly | | **Annual Filing** | `create_annual_filing`| 200.00 | Bundesanzeiger | | **Debt Collection** | `collect_debt` | 50.00 | Inkasso Automation | | **EU Presence** | `eu_presence_bundle` | 5,000.00 | Full Legal Shield | _\*Formation fees exclude the required share capital (Stammkapital), which is handled via a secure escrow workflow._ --- ## Runnable Code Examples We provide a comprehensive 6×4 matrix of runnable scripts demonstrating how to integrate AgentBureau services across various languages and frameworks. These examples handle the full x402 flow: **Challenge → Payment → Retry**. ### Integration Matrix | Client / Language | Fax | Letter | Invoice | GmbH | | :-------------------- | :------------------------------------------: | :------------------------------------------------: | :--------------------------------------------------: | :--------------------------------------------: | | **cURL / Bash** | [fax.sh](./examples/curl/fax.sh) | [letter.sh](./examples/curl/letter.sh) | [invoice.sh](./examples/curl/invoice.sh) | [gmbh.sh](./examples/curl/gmbh.sh) | | **Python (httpx)** | [fax.py](./examples/python/fax.py) | [letter.py](./examples/python/letter.py) | [invoice.py](./examples/python/invoice.py) | [gmbh.py](./examples/python/gmbh.py) | | **TypeScript (viem)** | [fax.ts](./examples/typescript/fax.ts) | [letter.ts](./examples/typescript/letter.ts) | [invoice.ts](./examples/typescript/invoice.ts) | [gmbh.ts](./examples/typescript/gmbh.ts) | | **LangChain** | [fax.py](./examples/langchain/fax.py) | [letter.py](./examples/langchain/letter.py) | [invoice.py](./examples/langchain/invoice.py) | [gmbh.py](./examples/langchain/gmbh.py) | | **Claude Tool Use** | [fax.py](./examples/claude-tool-use/fax.py) | [letter.py](./examples/claude-tool-use/letter.py) | [invoice.py](./examples/claude-tool-use/invoice.py) | [gmbh.py](./examples/claude-tool-use/gmbh.py) | | **OpenAI Responses** | [fax.py](./examples/openai-responses/fax.py) | [letter.py](./examples/openai-responses/letter.py) | [invoice.py](./examples/openai-responses/invoice.py) | [gmbh.py](./examples/openai-responses/gmbh.py) | ### How to Run the Examples 1. **Navigate to
