Tools of Criptonlabs Agent APIs
	Description		Read-only	Idempotent	Open world
`solana_latest_slot`Latest finalized Solana slot and its block time. When to use: To check how fresh the finalized view of Solana is, or to anchor a read to a slot. Prefer another tool: Not a tip-of-chain feed: it is finalized, not processed or confirmed, and it is cached for 2 seconds. Example: solana_latest_slot {}	Latest finalized Solana slot and its block time. When to use: To check how fresh the finalized view of Solana is, or to anchor a read to a slot. Prefer another tool: Not a tip-of-chain feed: it is finalized, not processed or confirmed, and it is cached for 2 seconds. Example: solana_latest_slot {}	No	Yes	Yes	Yes
`solana_network_health`Whether Solana data is currently being served: latest probe status and finalized slot. When to use: Before relying on the Solana verdict endpoints, or to explain a 503 from them. Prefer another tool: Not a measure of the Solana network itself, only of this service's access to it; use the latest-slot endpoint to see chain progress. Example: solana_network_health {}	Whether Solana data is currently being served: latest probe status and finalized slot. When to use: Before relying on the Solana verdict endpoints, or to explain a 503 from them. Prefer another tool: Not a measure of the Solana network itself, only of this service's access to it; use the latest-slot endpoint to see chain progress. Example: solana_network_health {}	No	Yes	Yes	Yes
`solana_token`Is this Solana token safe to hold or receive? A SAFE, WARN or DANGER verdict. When to use: Before accepting or swapping into an unfamiliar token, to see whether its mint can freeze, mint more, move or tax balances. Prefer another tool: Not a price, liquidity or holder lookup and not an audit of the token's project; it reads only the mint account. Example: solana_token {"mint":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"}	Is this Solana token safe to hold or receive? A SAFE, WARN or DANGER verdict. When to use: Before accepting or swapping into an unfamiliar token, to see whether its mint can freeze, mint more, move or tax balances. Prefer another tool: Not a price, liquidity or holder lookup and not an audit of the token's project; it reads only the mint account. Example: solana_token {"mint":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"}	No	Yes	Yes	Yes
`solana_transfer_readiness`Will this Solana transfer succeed? A verdict for SOL or an SPL or Token-2022 token. When to use: Before building or signing a Solana transfer, to learn whether it will fail and what it will cost in rent and fees. Prefer another tool: Not a simulation of the exact transaction (no priority fee, no program logic), not a token price or holder lookup, and not a way to read raw accounts. Example: solana_transfer_readiness {"source":"83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri","destination":"A1TMhSGzQxMr1TboBKtgixKz1sS6REASMxPo1qsyTSJd","mint":"SOL","amount":"0.5"}	Will this Solana transfer succeed?

Prefer another tool: Not a simulation of the exact transaction (no priority fee, no program logic), not a token price or holder lookup, and not a way to read raw accounts. Example: solana_transfer_readiness {"source":"83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri","destination":"A1TMhSGzQxMr1TboBKtgixKz1sS6REASMxPo1qsyTSJd","mint":"SOL","amount":"0.5"}	No	Yes	Yes	Yes
`xrpl_account_lines`One page of an account's trust lines, with an opaque cursor for the next page. When to use: To list every trust line of an account (balances, limits, freeze and authorization flags), page by page. Prefer another tool: For a quick capped overview with the XRP balance, use `/v1/xrpl/account/{address}/summary`; for issued totals of a token, use the token endpoint. Example: xrpl_account_lines {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	One page of an account's trust lines, with an opaque cursor for the next page. When to use: To list every trust line of an account (balances, limits, freeze and authorization flags), page by page. Prefer another tool: For a quick capped overview with the XRP balance, use `/v1/xrpl/account/{address}/summary`; for issued totals of a token, use the token endpoint. Example: xrpl_account_lines {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	No	Yes	Yes	Yes
`xrpl_account_summary`XRP balance, sequence, owner count, transfer rate and trust lines (capped) for an account. When to use: To inspect an account before building a transaction for it. Prefer another tool: Not for transaction history, reserves or account flags; it is a summary, not a full account dump. Example: xrpl_account_summary {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	XRP balance, sequence, owner count, transfer rate and trust lines (capped) for an account. When to use: To inspect an account before building a transaction for it. Prefer another tool: Not for transaction history, reserves or account flags; it is a summary, not a full account dump. Example: xrpl_account_summary {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	No	Yes	Yes	Yes
`xrpl_account_transactions`One page of an account's most recent validated transactions, newest first. When to use: To check what an account did recently (payments sent or received, offers, trust line changes) and whether each transaction succeeded. Prefer another tool: For balances and trust lines, use `/v1/xrpl/account/{address}/summary` or `/v1/xrpl/account/{address}/lines`; for full archival history, use a full-history node or indexer: history depth depends on the serving node and older pages may be slower. Example: xrpl_account_transactions {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	One page of an account's most recent validated transactions, newest first. When to use: To check what an account did recently (payments sent or received, offers, trust line changes) and whether each transaction succeeded. Prefer another tool: For balances and trust lines, use `/v1/xrpl/account/{address}/summary` or `/v1/xrpl/account/{address}/lines`; for full archival history, use a full-history node or indexer: history depth depends on the serving node and older pages may be slower. Example: xrpl_account_transactions {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	No	Yes	Yes	Yes
`xrpl_amm`AMM pool reserves and trading fee for an asset pair. When to use: To read AMM pool depth and fee for a pair. Prefer another tool: It does not estimate slippage or compare venues (use the slippage page for the CLOB vs AMM comparison); a pair without a pool returns 404. Example: xrpl_amm {"a":"XRP","b":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	AMM pool reserves and trading fee for an asset pair. When to use: To read AMM pool depth and fee for a pair. Prefer another tool: It does not estimate slippage or compare venues (use the slippage page for the CLOB vs AMM comparison); a pair without a pool returns 404. Example: xrpl_amm {"a":"XRP","b":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	No	Yes	Yes	Yes
`xrpl_fee`Current XRPL fee tiers in drops with a congestion score. When to use: Before submitting a transaction, to choose a `Fee` and to decide whether the network is congested. Prefer another tool: Not a price feed and not a historical series; it describes the latest validated ledger only. Example: xrpl_fee {}	Current XRPL fee tiers in drops with a congestion score. When to use: Before submitting a transaction, to choose a `Fee` and to decide whether the network is congested. Prefer another tool: Not a price feed and not a historical series; it describes the latest validated ledger only. Example: xrpl_fee {}	No	Yes	Yes	Yes
`xrpl_latest_ledger`Latest validated ledger index, hash and close time. When to use: To anchor other readings to a ledger or to check how current the network view is. Prefer another tool: Not for transaction data or account state; use the account endpoint for those. Example: xrpl_latest_ledger {}	Latest validated ledger index, hash and close time. When to use: To anchor other readings to a ledger or to check how current the network view is. Prefer another tool: Not for transaction data or account state; use the account endpoint for those. Example: xrpl_latest_ledger {}	No	Yes	Yes	Yes
`xrpl_network_health`Overall and per-node health of the upstream XRPL nodes. When to use: To decide whether to trust or retry data, or to explain a 503 from another endpoint. Prefer another tool: Not a probe of your own connectivity; it reports the service's upstream nodes. Example: xrpl_network_health {}	Overall and per-node health of the upstream XRPL nodes. When to use: To decide whether to trust or retry data, or to explain a 503 from another endpoint. Prefer another tool: Not a probe of your own connectivity; it reports the service's upstream nodes. Example: xrpl_network_health {}	No	Yes	Yes	Yes
`xrpl_orderbook`CLOB order book for a currency pair with unfunded offers removed. When to use: To read executable liquidity for a pair on the XRPL central limit order book (CLOB). Prefer another tool: Not for AMM liquidity (use the amm page) and not for a cost estimate (use the slippage page). Example: xrpl_orderbook {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}	CLOB order book for a currency pair with unfunded offers removed. When to use: To read executable liquidity for a pair on the XRPL central limit order book (CLOB).

`xrpl_paths`Multi-hop payment paths and their source cost. When to use: Before a cross-currency or multi-hop payment: to see whether a route exists and how much the source would spend to deliver the amount. A call can take up to about 20 seconds and paths may be non-optimal. Prefer another tool: To check whether a direct payment can succeed (use `/v1/xrpl/payment-readiness`), or for the single-hop cost of a trade on one pair (use `/v1/xrpl/slippage`, which compares the order book and the AMM). Example: xrpl_paths {"source":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","destination":"rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B","asset":"XRP","amount":"1"}	Multi-hop payment paths and their source cost. When to use: Before a cross-currency or multi-hop payment: to see whether a route exists and how much the source would spend to deliver the amount. A call can take up to about 20 seconds and paths may be non-optimal.

`xrpl_payment_readiness`Pre-payment check: can this payment from source to destination succeed now? When to use: Right before sending a payment: to catch a missing or unfunded destination, a required destination tag, deposit authorization, missing or frozen trust lines, insufficient balance and issuer freezes, in one call. Prefer another tool: To find a multi-hop route or the source amount needed for a cross-currency payment (use the paths endpoint), or to list balances (use `/v1/xrpl/account/{address}/summary`). Example: xrpl_payment_readiness {"source":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","destination":"rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B"}	Pre-payment check: can this payment from source to destination succeed now?

`xrpl_slippage`Slippage and average price for buying an amount of base currency. When to use: Before placing a market-style trade, to size it against available depth and to see whether the CLOB or the AMM pool is the cheaper venue. Prefer another tool: It is an estimate, not a quote, and it does not split an amount across venues or route through other pairs. To read pool reserves, use the amm page. Example: xrpl_slippage {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","amount":"1000"}	Slippage and average price for buying an amount of base currency.

Example: xrpl_slippage {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","amount":"1000"}	No	Yes	Yes	Yes
`xrpl_token`Issuer data for an issued asset: flags, domain, transfer fee and total issued. When to use: Before accepting or sending an issued token: check that the issuer exists, is not frozen, whether holders need authorization, and the transfer fee charged on every transfer between non-issuer accounts. Prefer another tool: For XRP (not an issued asset; 400), for one account's own balances use `/v1/xrpl/account/{address}/lines`, and for prices use `/v1/xrpl/orderbook` or `/v1/xrpl/amm/{a}/{b}`.
