## Tools (25)

- `solmachina_batch_token_risk`: Batch heuristic risk scan for up to 10 SPL token mints in ONE call (mint + freeze authority, Token-2022 dangerous extensions, top-10 holder concentration per token). A portfolio/watchlist bundle over the token-risk engine; each mint returns its own result or an explicit error. Transparent, conservative ('unknown' over guessing). NOT financial advice. Requires ?mints=<comma-separated mint addresses>.
- `solmachina_catalog`: Discover the x402 catalog (endpoints, USDC prices, category, network, payTo). FREE.
- `solmachina_decision`: SolMachina Decision — the decision layer for autonomous agents: composes on-chain risk signals into ONE answer — EXECUTE / REVIEW / REJECT + SMRI (SolMachina Machine Risk Index 0-100) + confidence + full evidence. A transparent RISK GATE against stated thresholds — NOT financial advice, NOT a profit prediction; returns REVIEW/unknown instead of guessing. Requires ?mint=<token mint address>; optional ?action=, ?amountUsd=, and a named firewall ?policy= (conservative|bluechip|anti-rug|degen).
- `solmachina_dex_quote`: Live aggregated Solana swap quote from the Jupiter aggregator: best-route output, price impact with stated thresholds (minimal/low/moderate/high), min-received after slippage, transparent route path, USD value and a freshness slot. A quote, NOT an execution guarantee (impact/liquidity move block to block). NOT financial advice. Requires ?inputMint=&outputMint=&amount= (amount in the input token's base units).
- `solmachina_epoch`: Live epoch info + ETA to epoch end (dual measured slot-rates labeled). Optional ?rate= selects which measured rate drives the ETA.
- `solmachina_how_to_pay`: Explain the x402 402->sign->retry flow so an agent can pay a paid endpoint with its own wallet. FREE.
- `solmachina_kamino_markets`: Kamino mainnet market list (trimmed JSON). Optional ?limit caps how many markets are returned.
- `solmachina_new_pairs`: Newest Solana liquidity pools (GeckoTerminal): name, base mint, creation time, age in minutes, liquidity, 24h volume and price change. New pools are UNVETTED and structurally high-risk — pair each mint with /v1/token-risk before acting. Factual observation only, NOT a recommendation. NOT financial advice. Optional ?limit (1-20, default 15).
- `solmachina_nft_collection`: Solana NFT collection snapshot from Magic Eden: floor price (SOL + lamports), listed count, 24h average price and 7-day volume. The floor is the lowest CURRENT ask (not a guaranteed sale price) and moves continuously. Factual snapshot, NOT a recommendation. NOT financial advice. Requires ?symbol=<Magic Eden collection symbol>.
- `solmachina_pretrade`: One-call PRE-TRADE SWEEP for a token: the full token-intel bundle (risk + executive digest + factual holder classification) PLUS a wallet-activity profile of the largest remaining holder PLUS observed priority-fee landing bands, distilled into a factual, threshold-stated checklist. Verdict-free (never 'buy'/'avoid'); partial sub-analyses are explicit errors, never silence. NOT financial advice. Requires ?mint=<token mint address>.
- `solmachina_priority_fee`: Solana priority-fee intelligence: the observed distribution (percentiles + suggested economy/normal/fast/aggressive bands) of prioritization fees actually paid in recent slots, in micro-lamports per compute unit. Optional ?accounts= narrows to txs write-locking specific markets. Observed history, NOT a prediction or inclusion guarantee.
- `solmachina_sample`: FREE preview of any endpoint: response shape/example, inputs and price — inspect before paying.
- `solmachina_sgp_checkpoint`: SolMachina's own Solana epoch-transition checkpoint series: the live epoch/slot reading (getEpochInfo via multi-RPC) measured against our accumulating on-disk series to yield a MEASURED slot-rate + ETA (not a model) and last epoch-transition detection. Optional ?n sets how many recent series points to return.
- `solmachina_simulate`: Pre-flight transaction simulation for agents: dry-run a serialized Solana transaction (simulateTransaction) BEFORE executing — will it succeed, compute units consumed, program logs, and the error if any. NEVER signs or sends; simulation only, NOT a guarantee of the real on-chain outcome. NOT financial advice. Requires ?tx=<base64 serialized transaction>.
- `solmachina_slippage_map`: Solana swap slippage / price-impact curve by trade SIZE: quotes the same pair at decade multiples of your base amount (via the Jupiter aggregator) and returns the impact per size plus a factual depth summary (largest tested size that stays under 1% / 5% impact). Execution intelligence beyond a single /v1/dex-quote. A quote, NOT an execution guarantee. NOT financial advice. Requires ?inputMint=&outputMint=&amount= (input base units).
- `solmachina_smri`: SolMachina Machine Risk Index (SMRI) for an SPL token: a 0-100 risk index (higher = lower assessed risk) with transparent components (contract authorities, top-10 concentration), a risk band, and confidence (= data completeness). The cheap, high-frequency score behind /v1/decision — for agents that just want the number. Verdict-free, returns 'unknown' over guessing. NOT financial advice. Requires ?mint=<token mint address>.
- `solmachina_status`: Trust/health snapshot: version, uptime, WAL entry count + SHA-256 chain head. FREE.
- `solmachina_tipfloor`: Jito bundle tip-floor snapshot + rolling history (p50/p95/p99/EMA). Optional ?fresh=true bypasses the ~60s cache for a live snapshot.
- `solmachina_token_holders`: Solana SPL token holder distribution / whale map: the largest token accounts (up to 20) each with its share of supply, plus top-1/5/10/20 concentration and simple buckets. More detailed than /v1/token-risk's single top-10 signal. Owners are NOT resolved and an account is not necessarily a distinct wallet; concentration is a structural signal, NOT a verdict. NOT financial advice. Requires ?mint=<token mint address>.
- `solmachina_token_intel`: One-call Solana token intelligence bundle: the full token-risk analysis PLUS a decision-ready executive digest and factual top-holder classification (burn/system labels; unknowns left unresolved with owner exposed). Verdict-free, transparent, conservative ('unknown' over guessing). NOT financial advice. Requires ?mint=<token mint address>.
- `solmachina_token_risk`: Heuristic Solana SPL token risk/signal scan: mint + freeze authority, Token-2022 dangerous extensions, top-10 holder concentration, plus best-effort holder-count/age context. Transparent methodology, conservative (reports 'unknown' over guessing). NOT financial advice. Requires ?mint=<token mint address>.
- `solmachina_trending_tokens`: Observed trending Solana tokens/pools (GeckoTerminal ranking of recent volume + activity): name, base mint, price + 1h/6h/24h change, 24h volume, liquidity, FDV, market cap, tx counts and pool age. Market-activity facts, NOT a recommendation, prediction or 'pump' signal — high volume does not imply safety. NOT financial advice. Optional ?limit (1-20, default 15).
- `solmachina_tx_inspect`: Decode a Solana transaction into a structured summary: success/fee/compute-units, the programs it invoked (named for well-known ones), SOL balance deltas and SPL token balance deltas. Reports on-chain effects only, never intent. Requires ?sig=<transaction signature>.
- `solmachina_verify_receipt`: How to verify a paid answer's Ed25519 SIR receipt OFFLINE (proof of what you paid for). FREE.
- `solmachina_wallet_scan`: Solana wallet activity profile: age, transaction activity, SOL balance, SPL token holdings, and a factual footprint band (fresh/active/heavy/empty). Transparent, conservative ('unknown' over guessing), never a trust/scam judgement. NOT financial advice. Requires ?address=<wallet address>.
