# Foundry GLEIF Record Baseline Change Detector

> Foundry GLEIF Record Baseline Change Detector is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-14).

Compares a caller-supplied baseline snapshot of GLEIF LEI record fields against the current live GLEIF data and reports which fields match, mismatch, or are unknown.

## Facts

- Endpoint: POST https://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/gleif-record-baseline-change
- Price: $0.006/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/foundry-gleif-record-baseline-change-detector-3e04750b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_cLu0SnGzLrh2262XuNN_F

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability foundry-gleif-record-baseline-change-detector-3e04750b -d '<json body>'
```

Example prompt: Check whether the GLEIF record for LEI 5493001KJTIIGC8Y1R12 still shows registrationStatus as ISSUED and legalName as 'Acme Holdings GmbH' — flag any fields that have changed or are unknown.

## When to prefer this

Use this endpoint when you need to detect drift between a previously recorded GLEIF LEI snapshot and the current live GLEIF data — ideal for compliance workflows, KYC/KYB refresh, pre-trade checks, and audit trails. Prefer this over the simple LEI lookup endpoint when you already have a baseline and need a structured diff rather than just the raw current record. Not suitable for medical, safety, ownership guarantees, or high-frequency monitoring.

## Known failure modes

- Invalid LEI format (must match ^[A-Z0-9]{18}\d{2}$) returns a validation error
- LEI not found in GLEIF registry returns null current values and UNKNOWN status for all fields
- baseline_fields array empty or exceeds 6 items causes schema rejection
- Field values longer than 200 characters are rejected
- GLEIF upstream API unavailable causes retrieval failure
- Stale cache may return data up to 60 seconds old

## How this service works

Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.

## Output

A JSON object containing per-field comparison results (status: MATCHED, MISMATCHED, or UNKNOWN), the current normalised GLEIF record values, source provenance (GLEIF LEI reference data, CC0 1.0 license), freshness metadata including retrieval timestamp and cache age, and lists of mismatched and unknown fields.
