16 tools

• 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…

• 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_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)…

• 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…

• 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_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…

• 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…

• 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…

• 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…

• 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…

• 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…

• 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 {}

• 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…

• 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…

• 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_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…
