Perpetual Market Liquidity-Risk Profiler
x402
Perpetual Market Liquidity-Risk Profiler is a paid API for AI agents from x402.presenceoperations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).
Returns a full liquidity-risk profile for a named perpetual market: absorbable notional at four slippage tolerances on both sides, bid-ask spread, book imbalance, top-of-book concentration, open interest, and day volume — with explicit book-depth limits on every response.

How this service works
Pay-per-call analytics on live perpetual-futures microstructure: what it costs to execute a size, what it costs to hold a position, and how much liquidity a market really has. USDC via x402 on Base, no account and no API key. Each response states the limit of its own instrument rather than implying none.
Output
A JSON object containing: depth array with absorbable notional at four slippage tolerances on both bid and ask sides; spread in basis points; book imbalance in basis points; top-of-book concentration on both bid and ask sides in basis points; mid price; open interest; day notional volume; book observation timestamp; levels visible (explicit limits of the visible book); and caveat/detail fields noting any limitations or caveats on the data.
Example use cases
Pre-trade slippage check for large order
“Before I send a $500K buy on ETH-PERP, tell me how much the book can absorb at 5, 10, 25, and 50 bps slippage on the ask side, and what the current spread looks like.”
Automated liquidity monitoring for risk dashboard
“Pull the liquidity-risk profile for BTC-PERP right now — I need the spread, imbalance, open interest, and day volume to update my risk dashboard.”
Comparing market depth across perpetuals
“I want to compare how liquid SOL-PERP is versus AVAX-PERP — can you get the absorbable notional at each slippage tolerance and the top-of-book concentration for both?”
Technical details
Endpoint
GEThttps://x402.presenceoperations.com/services/liquidity-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, multi-dimensional liquidity-risk snapshot of a specific perpetual market — particularly when you need absorbable notional at multiple slippage tolerances simultaneously along with spread, imbalance, and concentration metrics in a single call. Prefer this over sibling endpoints when you need a broad risk profile rather than a point execution cost estimate (use the execution-cost sibling for that) or funding rate data. Ideal for pre-trade risk assessment, risk dashboards, and liquidity comparisons across markets.
Side effects
- Invalid market symbol format (must match ^[A-Z0-9]{1,16}-PERP$) returns a 400-level error
- Market not found or not supported returns an error or empty depth response
- Stale book data — timestamp in bookObservedAt may lag real market conditions
- Thin book — levelsVisible may be low, limiting slippage profile accuracy; caveat field will note this
- Payment failure (x402 protocol) — 402 response if payment not provided or insufficient
