## API endpoints

| Service         | Base URL                                                   |
| --------------- | ---------------------------------------------------------- |
| Orchestrator    | `https://v1.orchestrator.rhinestone.dev`                   |
| Deposit Service | `https://v1.orchestrator.rhinestone.dev/deposit-processor` |

Authentication: pass your API key in the `x-api-key` header. [Request a key](https://tally.so/r/wg22x4). Pin a version with `x-api-version: 2026-04.blanc` — see [API versioning](/intents/guides/api-versioning).

## Key endpoints

| Endpoint                        | Method | Purpose                                 |
| ------------------------------- | ------ | --------------------------------------- |
| `/quotes`                       | POST   | Get a quote for an intent               |
| `/intents`                      | POST   | Submit a signed intent                  |
| `/intents/{id}`                 | GET    | Track intent status                     |
| `/accounts/{address}/portfolio` | GET    | Fetch user token balances across chains |

## Supported chains

See [Supported chains](/home/resources/supported-chains) for the full list with token addresses.

## Account types

| Type                    | Description                                    | SDK config                                       |
| ----------------------- | ---------------------------------------------- | ------------------------------------------------ |
| Smart Account (default) | ERC-7579 modular account (Safe, Kernel, Nexus) | `accountType: 'safe'` (or `'kernel'`, `'nexus'`) |
| Plain EOA               | Standard externally owned account              | `accountType: 'eoa'`                             |
| Smart EOA (EIP-7702)    | EOA with smart account capabilities            | `accountType: 'eip7702'`                         |

## Transaction path

The default transaction path is **Warp** (native relay). ERC-4337 userops are opt-in.

| Scenario                            | Path                                                 |
| ----------------------------------- | ---------------------------------------------------- |
| Crosschain, built-in swap, bridging | Warp (default)                                       |
| Same-chain, ERC-4337 bundler needed | Use `sendUserOperation` instead of `sendTransaction` |

## Common error codes

All non-2xx responses share the envelope `{ code, message, traceId, details? }`. Switch on `code`.

| Code                     | HTTP | Meaning                                                                                 | Fix                                                         |
| ------------------------ | ---- | --------------------------------------------------------------------------------------- | ----------------------------------------------------------- |
| `VALIDATION_ERROR`       | 400  | Request didn't validate (bad chain id, missing version header, unsupported token, etc.) | Inspect `details[]` and correct the payload                 |
| `UNAUTHORIZED`           | 401  | API key missing or invalid                                                              | Pass your key in `x-api-key`                                |

| `INSUFFICIENT_LIQUIDITY` | 422  | Account can't cover the intent given gas and fees                                       | Check balance; see `details.availableIntents` for fallbacks |
| `TOO_MANY_REQUESTS`      | 429  | Rate limited                                                                            | Honour `Retry-After`                                        |
