The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
lighter_account Lighter account state ~129
Collateral, open positions, and account value for one Lighter sub-account. Defaults to the account in LIGHTER_ACCOUNT_INDEX. Pass a market selector to include the resting orders on that market. Order listing needs either a read-only token or a signing key, since Lighter authenticates that route.
| Name | Type | Req | Description |
|---|---|---|---|
| account_index | integer | – | Sub-account to read. Defaults to the configured account. |
| market_id | integer | – | Market id, for example 182 for H100. Use this or symbol. |
| symbol | string | – | Market ticker, for example H100. Use this or market_id. |
No output schema declared.
No examples provided.
lighter_cancel Cancel a Lighter order ~108
Cancel one resting order by market and order index. Read the order index from lighter_account with a market selector.
| Name | Type | Req | Description |
|---|---|---|---|
| market_id | integer | – | Market id, for example 182 for H100. Use this or symbol. |
| order_index | string | yes | Exchange-assigned order index, as a decimal string. It exceeds the safe integer range, so pass it exactly as lighter_account reported it. |
| symbol | string | – | Market ticker, for example H100. Use this or market_id. |
No output schema declared.
No examples provided.
lighter_cancel_all Cancel all Lighter orders ~44
Cancel every resting order on the configured sub-account, across all markets. Lighter cancels account-wide, so this cannot be scoped to one market. Open positions are untouched.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
lighter_funding Lighter funding rates ~168
Current funding rates and settled funding history. The current rate is a fraction charged over one 8 hour period, and settled history is an hourly percent, so each number carries its unit in the response. A positive rate means longs pay shorts. Omit both selectors to rank Lighter's own markets by the largest rate. Rates from the other venues Lighter tracks are reference data and are left out, since a position opened here collects Lighter's rate.
| Name | Type | Req | Description |
|---|---|---|---|
| history_limit | integer | – | Settled hourly funding payments to return for the selected market, 0 to 50. |
| market_id | integer | – | Market id, for example 182 for H100. Use this or symbol. |
| symbol | string | – | Market ticker, for example H100. Use this or market_id. |
No output schema declared.
No examples provided.
lighter_h100 H100 compute price ~116
Price, funding, and book depth for market 182 (H100), a perpetual on the rental cost of an NVIDIA H100. Use it to read the traded cost of compute and to see which side funding pays before hedging a GPU bill. The H100 book is thin: about $7,100 of 24 hour volume, open interest near $10,000, and 4.00 of size at the top of book on each side when measured on 2026-08-26. Size hedges accordingly.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
lighter_hedge_h100 Hedge H100 compute cost ~260
Size a hedge on market 182 (H100) for a number of GPU hours, price it against the live book, and report the funding it earns or pays. A short covers a renter against rising compute prices. This tool is a dry run and returns a plan. It signs and sends the order only when execute is true, and max_notional_usd is required either way. A Lighter API key is full write authority over the account it is bound to, so run this server against a dedicated sub-account funded with only what the agent may lose.
| Name | Type | Req | Description |
|---|---|---|---|
| execute | boolean | – | Set true to sign and send the hedge. Left false, the tool returns the plan and sends nothing. |
| gpu_hours | number | yes | H100 hours of rental cost to cover. One unit of base is one GPU hour. |
| max_notional_usd | number | yes | Required ceiling on order notional in USD. The order is refused when its worst-case notional exceeds this value. There is no default. |
| side | string | – | short covers a buyer of compute against rising prices. long covers a seller of compute against falling prices. |
| slippage_bps | number | – | Average execution bound in basis points from the touch. |
No output schema declared.
No examples provided.
lighter_market Lighter market detail ~96
Mark price, index price, funding rate, and top of book for one market. Select the market by market_id or by symbol.
| Name | Type | Req | Description |
|---|---|---|---|
| depth | integer | – | Order book levels per side, 1 to 20. |
| market_id | integer | – | Market id, for example 182 for H100. Use this or symbol. |
| symbol | string | – | Market ticker, for example H100. Use this or market_id. |
No output schema declared.
No examples provided.
lighter_markets List Lighter markets ~111
List or search the perpetual markets on a Lighter deployment. Mainnet lists id 182, H100, a perpetual on the rental cost of an NVIDIA H100, which the response always includes. Results are capped and the response reports the full count, so pass a query to narrow the list.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum markets to return, 1 to 100. |
| query | string | – | Case-insensitive substring match on the ticker, for example "H100" or "SOL". |
No output schema declared.
No examples provided.
lighter_place_order Place a Lighter order ~349
Sign and send one limit or market order. max_notional_usd is required and has no default. The order is priced against one book snapshot and refused above the ceiling before it is signed, so the order that goes out is the order that was checked. The server applies its own configured ceiling as well, and the lower of the two wins. A Lighter API key is full write authority over the account it is bound to, so run this server against a dedicated sub-account funded with only what the agent may lose.
| Name | Type | Req | Description |
|---|---|---|---|
| market_id | integer | – | Market id, for example 182 for H100. Use this or symbol. |
| max_notional_usd | number | yes | Required ceiling on order notional in USD. The order is refused when its worst-case notional exceeds this value. There is no default. |
| order_type | string | – | limit rests on the book. market is immediate-or-cancel with an average execution bound. |
| price | number | – | Limit price in quote units. Required for a limit order. |
| reduce_only | boolean | – | Refuse to open or increase a position. A reduce-only order can only shrink an existing position, so it is exempt from max_notional_usd and from the market size floor. |
| side | string | yes | Order side. |
| size | number | yes | Order size in base units, in human decimals. |
| slippage_bps | number | – | Average execution bound for a market order, in basis points. |
| symbol | string | – | Market ticker, for example H100. Use this or market_id. |
| time_in_force | string | – | Resting behaviour for a limit order. Defaults to gtt. |
