NEAR Intents Integration

Cross-chain token swaps via 1Click REST API. Get a quote, API provides deposit addresses, you build the deposit transaction and receive the resulting token automatically.

Quick Start - Pick Your Path

Integration Flow

GET /v0/tokens → POST /v0/quote (dry) → POST /v0/quote (wet) → Deposit TX → POST /v0/deposit/submit → GET /v0/status

Rule Categories

Critical Knowledge

1. Use assetId from /v0/tokens - never construct manually
2. dry: true = preview only, dry: false = get deposit address (valid ~10 min)
3. Poll status until terminal: SUCCESS, FAILED, REFUNDED, INCOMPLETE_DEPOSIT
4. Chain-to-chain is default - depositType and recipientType default to chain endpoints
