# Base URL

> The Nito API host and SDK base URLs.

All endpoints use `https://app.trynito.ai`.

| Surface | Path |
| - | - |
| Chat Completions, Responses, Messages, and models | `/v1/...` |
| Fusion | `/api/v1/chat/fusion` |
| Web retrieval | `/api/v1/web/search`, `/api/v1/web/fetch` |
| Document parsing | `/api/v1/attachments/parse` |
| API-key management | `/api/v1/api-keys`, `/api/v1/api-keys/{key_id}` |
| Billing balance | `/api/v1/billing/balance` |
| Rate-limit snapshots | `/api/v1/rate-limits` |
| Attestation | `/api/v1/attestation` |
| MCP | `/mcp` |

OpenAI-style SDKs append `/chat/completions` themselves, so set their base URL to `https://app.trynito.ai/v1`. The Anthropic SDK appends `/v1/messages`, so set its base URL to `https://app.trynito.ai`.
