Example prompt: Can you pull up the research dossier on Base gas fees so I can understand how transaction costs work on the Base network?

## When to prefer this

Choose this endpoint when you need a structured, pre-researched explanation of Base gas fees without having to synthesize information yourself. It is ideal for agents that need to quickly educate users on Base L2 fee mechanics or enrich responses about blockchain transaction costs. Prefer this over real-time gas fee APIs when conceptual explanation rather than live fee data is needed.

## Known failure modes

- Payment failure: x402 payment not accepted or insufficient USDC balance
- Endpoint unavailable: Tailscale host predator-ubuntu offline
- 404-style error if the dossier slug is not found
- Timeout if the host is slow to respond
