MEV Builder Inclusion Analyzer
x402
MEV Builder Inclusion Analyzer 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 (inclusion delay, builder concentration, censorship gap) to classify MEV-related builder inclusion risk for a given blockchain address, transaction, or protocol.

How this service works
Builder Inclusion Analyzer 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 risk classification for the subject (e.g. high/medium/low inclusion risk), the confidence level of the classification, the exact thresholds applied to each metric, a list of any missing signals that lowered confidence, and the correlated context labels passed in by the caller.
Example use cases
Transaction censorship investigation
“I need to check if my transaction 0xdef456 was likely censored by block builders — I observed an inclusion delay of 6 blocks, a builder concentration of 85%, and a censorship gap of 22%. Can you run a builder inclusion analysis on it?”
Protocol MEV risk assessment
“Assess builder inclusion risk for the Uniswap v3 USDC/ETH pool — I have evidence showing builder concentration at 63% and an inclusion delay of 2 blocks observed yesterday at 14:30 UTC. Don't use strict mode since I'm missing the censorship gap metric.”
Wallet address compliance monitoring
“Run a builder inclusion analysis on wallet address 0x789abc — my latest data shows inclusion_delay_blocks of 8, censorship_gap_pct of 30%, and builder_concentration_pct of 91% as of 2024-06-01T10:00:00Z. Flag any missing signals explicitly.”
Technical details
Endpoint
POSThttps://mev.halowerk.com/v1/builder-inclusion-analyzer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, evidence-based classification of MEV builder inclusion risk using caller-supplied on-chain signals — particularly when you have inclusion delay, builder concentration, or censorship gap data and need explicit threshold disclosure, confidence scoring, and missing-signal reporting rather than a black-box result. Prefer it over general blockchain analytics APIs when the specific focus is block builder censorship behavior and MEV inclusion patterns.
Side effects
- Insufficient evidence items (fewer than 1 evidence object) returns a validation error
- strict mode rejects requests missing any of the three documented metrics
- Malformed timestamps or metric values outside expected ranges cause schema validation errors
- Ambiguous or repeated metric observations without timestamps may reduce confidence without error
- Subject string exceeding 256 characters is rejected
- More than 50 evidence items triggers a payload size error
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. |
