# SiloRail Network Index

This host is the canonical SiloRail network index. It is not an OpenAI-compatible
gateway and it does not process chat, pricing, model, payment, or settlement
requests.

Agents must choose exactly one network and use that network's api_base.

## Selection Rules For Agents

- Use testnet for integration tests, examples, demos, and automated dry runs.
- Use mainnet only when the payer intentionally wants to spend real USDC.
- Never infer the desired network from this apex host.
- Never rewrite https://silorail.com/v1/... into an API call. This host is an
  index only.
- Read the selected network's /llms.txt before signing or requesting payment.
