Airdrop Eligibility Verifier
x402
Airdrop Eligibility Verifier is a paid API for AI agents from dao.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).
Analyses caller-supplied evidence signals to classify whether a subject (address, protocol, proposal, etc.) meets airdrop eligibility criteria, returning confidence scores and explicit threshold details.

How this service works
Airdrop Eligibility Verifier 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 an eligibility classification (eligible/ineligible/uncertain) with an explicit confidence score, the exact threshold values used in the assessment, a list of any missing or low-confidence signals, and the original context labels for correlation.
Example use cases
DAO token drop eligibility audit
“I need to verify whether wallet 0x1234...abcd is eligible for our DAO's upcoming token airdrop — I have evidence: failed_criteria=1, snapshot_mismatch=false (source: snapshot.org, observed 2024-10-15T08:00:00Z), and claim_window_gap_days=0 (source: claim-tracker, observed 2024-10-16T10:00:00Z). Don't use strict mode since I might be missing some signals.”
Disqualification check for snapshot mismatch
“Check if subject 'Protocol-Alpha-Airdrop' should be disqualified due to a snapshot mismatch — evidence: snapshot_mismatch=true (source: subgraph-query-01, observed 2024-12-01T00:00:00Z) and failed_criteria=3 (source: eligibility-checker, observed 2024-12-01T01:00:00Z). Run it in strict mode and list any missing signals.”
Claim window gap impact assessment
“Assess the airdrop eligibility for address 0xDeAd...BeeF given that the claim window gap was 14 days (source: claim-api, observed 2025-01-10T15:30:00Z) and there were 0 failed criteria (source: rules-engine, observed 2025-01-10T14:00:00Z) — tell me the confidence score and exactly which thresholds were used.”
Technical details
Endpoint
POSThttps://dao.halowerk.com/v1/airdrop-eligibility-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, evidence-based eligibility classification for airdrops using caller-supplied signals rather than live chain queries. It is ideal when you already have extracted eligibility metrics (failed_criteria, snapshot_mismatch, claim_window_gap_days) and need an auditable classification with explicit thresholds and confidence scores. Prefer it over on-chain query tools when you want reproducible, documented assessments that enumerate missing signals rather than silently assuming defaults.
Side effects
- Missing required 'evidence' array or empty array returns 400 validation error
- Strict mode enabled but not all documented metrics supplied — request rejected with list of missing metrics
- Invalid metric enum value in evidence items causes schema validation failure
- Malformed ISO-8601 timestamp on evidence items causes parsing error
- Subject string exceeds 256 character limit returns 400
- More than 50 evidence items supplied exceeds maxItems constraint
- Payment not provided or insufficient — x402 payment required response
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. |
