AMM Invariant Monitor
x402
AMM Invariant Monitor is a paid API for AI agents from mev.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).
Analyzes caller-supplied evidence to detect AMM invariant deviations, reserve mismatches, and unexplained deltas, returning a confidence-weighted classification with explicit thresholds.

How this service works
AMM Invariant Monitor analyses only the evidence supplied by the caller. It does not claim to query a chain, identify a legal status or replace an independent audit. Missing signals lower confidence and are listed explicitly; every classification includes the exact thresholds used.
Output
Returns a classification of the AMM pool's invariant health with confidence score, the exact thresholds applied, a list of any missing signals that lowered confidence, and the assessed values for invariant_deviation_pct, reserve_mismatch_pct, and unexplained_delta_count based on the newest-timestamped evidence supplied.
Example use cases
Post-swap manipulation check
“I just saw a suspicious large swap on pool 0xDEAD...BEEF — can you assess it for invariant violations? Invariant deviation is 5.1%, reserve mismatch is 1.4%, and I recorded 7 unexplained deltas at 2024-06-20T09:15:00Z from my Dune query.”
Pre-trade AMM integrity verification
“Before I route a $500k trade through this Curve pool at address 0x1234...5678, check its integrity — I've got reserve mismatch at 0.2%, invariant deviation at 0.05%, and zero unexplained deltas as of 2024-06-21T08:00:00Z from my own RPC node.”
Real-time MEV alert triage
“We're seeing weird activity on pool 0xCAFE...BABE — run an AMM invariant monitor assessment with strict mode off; invariant deviation is 12.7%, reserve mismatch is 3.2%, and 15 unexplained deltas from our block explorer feed at 2024-06-21T11:45:00Z.”
Technical details
Endpoint
POSThttps://mev.halowerk.com/v1/amm-invariant-monitor?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have caller-supplied AMM metric observations and need a fast, explainable invariant-health classification without requiring direct chain access — especially useful for MEV alerting pipelines, pre-trade risk checks, or audit workflows where you already have reserve and delta data extracted from subgraphs, RPC nodes, or block explorers.
Side effects
- Missing required evidence items cause reduced confidence or rejection in strict mode
- Malformed ISO-8601 timestamps result in evidence being ignored or errored
- Supplying no evidence or an empty array returns a validation error
- Strict mode enabled with incomplete metrics returns a rejection response
- Unrecognized metric names are rejected by schema validation
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| strict | boolean | Reject unless all documented metrics are supplied. |
| context | object | Optional non-secret labels returned unchanged for correlation. |
| subject | string | Address, transaction, protocol, asset, proposal or other subject being assessed. |
| evidence | array | Caller-supplied observations. Repeated metrics form a time series; the newest timestamp is assessed. |
