OnchainPulse Exit-Depth / Sell-Impact Estimator is a paid API for AI agents from onchainpulse.theaslangroupllc.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).
Estimates how many tokens can be sold at 1/2/5/10/25% price impact thresholds for any Uniswap-v3-compatible pool across 11 chains, using live on-chain liquidity math and DexScreener cross-validation.

How this service works
Exit-depth / sell-impact estimator for Uniswap-v3-compatible AND v2-style (x·y=k) pools on 11 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, Avalanche, Monad, World Chain, HyperEVM, Robinhood Chain): live pool state read from the contract (v3 sqrtPrice + in-range liquidity, or v2 reserves); tokens sellable at 1/2/5/10/25% price impact in tokens, quote and USD, %-of-supply framing, manipulated-liquidity cross-check vs DexScreener. Deterministic pool math, no LLM — the "can I actually g
Output
Returns live sqrtPrice and in-range liquidity read directly from the pool contract, plus token amounts sellable at each price impact tier (1/2/5/10/25%) expressed in base tokens, quote tokens, and USD. Also includes a percent-of-supply framing and a manipulated-liquidity cross-check comparing on-chain data against DexScreener, giving a definitive 'can I actually get out?' answer.
Example use cases
Pre-trade slippage check for large position
“I'm about to sell 500,000 tokens of this Arbitrum memecoin — can you tell me how much I can unload at 5% and 10% price impact on Uniswap v3 before I crater the price?”
Rug-pull liquidity authenticity check
“Before I buy into this new Base token, can you check whether the Uniswap pool liquidity is real or if it looks manipulated — run the exit depth estimator and compare it against DexScreener.”
Portfolio exit planning across chains
“I hold a big bag of an Optimism token and need to plan my exit — show me how much I can sell at 1%, 2%, 5%, and 25% price impact tiers and what percentage of the total supply that represents.”
Technical details
Endpoint
GEThttps://onchainpulse.theaslangroupllc.com/api/exit-depth?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, math-based on-chain liquidity depth analysis for Uniswap v3-compatible pools — especially when evaluating whether a large position can be exited without excessive slippage, or when verifying that reported liquidity is not manipulated. Prefer this over general DeFi data APIs when you need the specific 'tokens sellable at X% price impact' framing with USD values and supply-percent context across multiple chains. Ideal for pre-trade due diligence, risk management, and rug-pull detection workflows.
Side effects
- Invalid or non-existent pool address returns an error or empty liquidity data
- Unsupported chain identifier returns a chain-not-supported error
- Pool with zero in-range liquidity returns zero sellable amounts at all impact tiers
- DexScreener data unavailable causes cross-check to be skipped or flagged as incomplete
- Network RPC timeout on target chain results in stale or missing sqrtPrice data
- Extremely thin liquidity pools may return very small USD values that appear nonsensical
