Criptonlabs Agent APIs bronze
api.criptonlabs.com
“Read-only XRP Ledger and Solana data for agents: XRPL fees, funded order books, slippage, AMM pools, account summaries and network health, and Solana transfer readiness, token and network health verdicts. Built for agentic payments: run pre-payment checks on fees, network health and account state before building a transaction. The A2A endpoint /a2a is free JSON-RPC: call SendMessage with a data part {skill, arguments}. The paid MCP endpoint /mcp/pro: tools payable per call are paid via x402 in USDC or EURC on Solana mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp, mints USDC EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, EURC HzwqbKZw8HxMN6bF2yFZNrht3c2iXXzpKcFu7uBEDKtr), VAT included. Also payable on XRPL mainnet (xrpl:0): the only accepted asset is RLUSD (issuer rMxCKbEDwqr76QuheSUMdEGf4B9xJ8m5De, currency 524C555344000000000000000000000000000000); XRP, any other issued currency and other issuers are refused, and the Payment must deliver exactly the price.

What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of api.criptonlabs.com controls every word below.
Fee intelligence
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 {} Credits only: paid by prepaid credit, 0.0005 EUR or 0.0006 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_fee {}
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 {} Credits only: paid by prepaid credit, 0.0005 EUR or 0.0006 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_latest_ledger {}
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 {} Credits only: paid by prepaid credit, 0.0005 EUR or 0.0006 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_network_health {}
Funded order book
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"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_orderbook {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}
Slippage estimate
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"} Paid: 0.01452 USDC or 0.0121 EURC per call on Solana mainnet, VAT included.
- Use xrpl_slippage {"base":"XRP","quote":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","amount":"1000"}
AMM pool
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"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_amm {"a":"XRP","b":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}
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"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_account_summary {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}
Account trust 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"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_account_lines {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}
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"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_account_transactions {"address":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}
Token issuer
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}`. Example: xrpl_token {"asset":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use xrpl_token {"asset":"USD.rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}
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"} Paid: 0.01452 USDC or 0.0121 EURC per call on Solana mainnet, VAT included.
- Use xrpl_payment_readiness {"source":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","destination":"rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B"}
Payment 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"} Paid: 0.02904 USDC or 0.0242 EURC per call on Solana mainnet, VAT included.
- Use xrpl_paths {"source":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh","destination":"rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B","asset":"XRP","amount":"1"}
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"} Paid: 0.01452 USDC or 0.0121 EURC per call on Solana mainnet, VAT included.
- Use solana_transfer_readiness {"source":"83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri","destination":"A1TMhSGzQxMr1TboBKtgixKz1sS6REASMxPo1qsyTSJd","mint":"SOL","amount":"0.5"}
Solana token verdict
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"} Credits only: paid by prepaid credit, 0.001 EUR or 0.0012 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use solana_token {"mint":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"}
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 {} Credits only: paid by prepaid credit, 0.0005 EUR or 0.0006 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use solana_latest_slot {}
Solana data status
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 {} Credits only: paid by prepaid credit, 0.0005 EUR or 0.0006 USD units per call; buy a bundle first at https://api.criptonlabs.com/v1/pro/credits/{bundle} or with `credits_topup`, then call with the `clc_` token or Sign-In-With-X.
- Use solana_network_health {}
