Network Names

Use these normalized network names in all API calls:

Network	Value	Used For
Native chains	`Mainnet`	BTC, XMR, ETH (native), LTC, DOGE, XRP, BCH, ADA, XLM, SOL, BNB, TRX

KYC & Logging Ratings

Providers are rated on two axes. Use these to filter for your privacy needs:

KYC Rating (kyc param): How much identity verification is required.

Grade	Meaning
`A`	No KYC at all
`B`	Light KYC (email or IP-based limits)
`C`	Moderate KYC (may require ID for larger amounts)
`D`	Any (no filter)

Logging Policy (log param): How much transaction data the provider retains.

Grade	Meaning
`A`	No logs / fully private
`B`	Minimal logs
`C`	Any (no filter)

For maximum privacy, use kyc=A&log=A.

Common Workflows

Standard Swap (Estimate, Create, Poll)

Step 1: Get quotes
  GET /v2/exchange/estimate?from=btc&to=xmr&amount=0.5

Step 2: Pick the best route and create the trade
  POST /v2/exchange/create
  {
    "engine": "<route.engine>",
    "provider": "<route.provider>",
    "from_currency": "btc",
    "to_currency": "xmr",
    "amount_from": 0.5,
    "address_to": "<user_xmr_address>"
  }

Step 3: Send crypto to the depositAddress from the response

Step 4: Poll status until FINISHED
  GET /v2/exchange/status/<trade_id>?engine=<engine>

Privacy Bridge (Ghost Protocol)

Step 1: Get bridge quotes
  GET /v2/exchange/bridge/estimate?from=eth&to=btc&amount=2

Step 2: Create the bridge (picks a route)
  POST /v2/exchange/bridge/create
  {
    "engine": "<route.engine>",
    "from_currency": "eth",
    "to_currency": "btc",
    "amount_from": 2,
    "address_to": "<user_btc_address>",
    "refund_address": "<user_eth_address>"
  }

Step 3: Send crypto to the first leg's depositAddress

Step 4: Poll both trade legs
  GET /v2/exchange/status/<leg1_id>?engine=<engine>
  GET /v2/exchange/status/<leg2_id>?engine=<engine>

Rate Comparison

# Compare all providers for 1000 USDT (TRC20) -> BTC
GET /v2/exchange/estimate?from=usdt&from_net=TRC20&to=btc&to_net=Mainnet&amount=1000

# Compare only no-KYC providers
GET /v2/exchange/estimate?from=usdt&from_net=TRC20&to=btc&to_net=Mainnet&amount=1000&kyc=A&log=A

Error Handling

All errors return JSON with an error field:

{ "error": "Invalid amount" }

HTTP Code	Meaning
400	Bad request (missing/invalid params)
404	Trade or resource not found
500	Provider or server error

When the estimate endpoint has no available routes, it returns:

{ "routes": [], "amount_to": 0 }

Tips for AI Agents

Always estimate first. Do not hardcode provider names; they change. Use the estimate response to get the current best engine and provider.
Respect minimums. Check minimum from the currencies endpoint before attempting a swap.
Poll with backoff. When checking status, poll every 15-30 seconds. Most swaps complete in 5-30 minutes.
Handle memo coins. XRP, XLM, and some others require a depositMemo. Always check the create response for depositMemo and include it in the deposit transaction.
Validate addresses before creating trades. Use the /v2/exchange/validate endpoint to avoid failed trades.
Use the engine param on status checks for faster lookups when you know which engine handled the trade.
