How this service works
Before an AI agent executes on Solana, it asks SolMachina: risk + a decision (EXECUTE/REVIEW/REJECT) + an SMRI score + a signed receipt, paid per call over x402 in USDC. Trust-first — cites every source, says 'unknown' over guessing. No account, no API key.
Output
Returns a structured slippage map with a 'pair' object identifying inputMint and outputMint, a 'depth' object showing the maximum USD tradeable under 1% and 5% price impact thresholds, a 'points' array with per-size-band entries (multiplier, swap USD value, size in base units, price impact percentage, and band label), and the baseAmount used as reference. This gives the agent a full picture of market depth and cost of liquidity at multiple trade sizes.
Example use cases
Pre-trade slippage check for large swap
“I'm about to swap 5,000,000,000 lamports of SOL into USDC on Solana — can you get the slippage map for that pair at multipliers 0.1, 1, 10, and 100 so I can see if the market depth is good enough to avoid more than 1% price impact?”
Liquidity depth scan for a memecoin exit
“I hold a large bag of this Solana token (mint: DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263) and want to sell into USDC — pull the SolMachina slippage map using a base amount of 1000000 with multipliers 1, 10, 100 so I can see how much I can offload before slippage blows past 5%.”
Automated agent trade-size optimizer
“My trading agent is deciding how much BONK to sell for USDC right now — fetch the slippage map for BONK (DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263) to USDC with a base amount of 1000000 lamports and slippage tolerance of 100 bps, so it can pick the largest size that still falls under 1% price impact.”
Technical details
Endpoint
GEThttps://api.solmachina.com/v1/slippage-mapWhen to prefer
Use SolMachina Slippage Map when an AI agent or trader needs to assess Solana DEX liquidity depth before committing to a trade — especially for large or multi-size swaps where price impact risk is material. Prefer this over a simple quote endpoint when you need to understand the full slippage curve across trade sizes, not just a single quote. Ideal for pre-trade risk gating, position sizing, and automated agent decision-making on Solana.
Side effects
- Unknown or illiquid mint address returns empty depth or error
- Amount specified in wrong units (e.g. whole SOL instead of lamports) causes misleading results
- Unsupported token pair with no on-chain DEX routes returns no data
- Stale or low-liquidity pool data may cause inaccurate price impact estimates
- Payment failure over x402 (insufficient USDC balance) blocks the request
- Invalid Base58 mint address returns a 400 validation error
- Too many multipliers (>8) causes request rejection
