Sage Coins & Addresses

Coin queries and address management.

Endpoints

Coin Queries

Endpoint	Payload	Description
`get_coins`	See below	List coins with filters
`get_coins_by_ids`	`{"coin_ids": [...]}`	Get specific coins
`get_are_coins_spendable`	`{"coin_ids": [...]}`	Check spendability
`get_spendable_coin_count`	`{"asset_id": null}`	Count spendable

get_coins Payload

{
  "asset_id": null,
  "offset": 0,
  "limit": 50,
  "sort_mode": "created_height",
  "filter_mode": "selectable",
  "ascending": false
}

Sort modes: "coin_id", "amount", "created_height", "spent_height", "clawback_timestamp"

Filter modes: "all", "selectable", "owned", "spent", "clawback"

Address Operations

Endpoint	Payload	Description
`check_address`	`{"address": "xch1..."}`	Validate address
`get_derivations`	`{"hardened": false, "offset": 0, "limit": 50}`	Get derivations
`increase_derivation_index`	`{"index": 100, "hardened": true, "unhardened": true}`	Generate more

Asset Ownership

Endpoint	Payload	Description
`is_asset_owned`	`{"asset_id": "..."}`	Check if owned

Coin Record Structure

{
  "coin_id": "0x...",
  "parent_coin_info": "0x...",
  "puzzle_hash": "0x...",
  "amount": "1000000000000",
  "asset_id": null,
  "created_height": 1234567,
  "spent_height": null,
  "clawback_timestamp": null
}

Derivation Record Structure

{
  "index": 0,
  "hardened": false,
  "address": "xch1...",
  "puzzle_hash": "0x...",
  "public_key": "0x..."
}

Examples

# List XCH coins
sage_rpc get_coins '{"asset_id": null, "limit": 20}'

# List CAT coins
sage_rpc get_coins '{"asset_id": "a628c1c2...", "limit": 20}'

# Check address
sage_rpc check_address '{"address": "xch1abc..."}'

# Check if coins are spendable
sage_rpc get_are_coins_spendable '{"coin_ids": ["0xabc...", "0xdef..."]}'

# Get address derivations
sage_rpc get_derivations '{"hardened": false, "offset": 0, "limit": 10}'

# Generate more addresses
sage_rpc increase_derivation_index '{"index": 200, "hardened": true, "unhardened": true}'

Notes

asset_id: null queries XCH coins
filter_mode: "selectable" returns only spendable coins
Address validation checks format and wallet ownership
