# Biodiversity Credit Integrity & Lifecycle Gauge (Region)

> Biodiversity Credit Integrity & Lifecycle Gauge (Region) is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).

Delivers a three-leg forensic snapshot of a biodiversity credit region: standard-body registry pressure, current project lifecycle status, and market/compliance cascade signals for ESG due diligence.

## Facts

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 biodiversity-credit-integrity-lifecycle-gauge-region-589fee1b
```

Example prompt: Can you pull the full biodiversity credit integrity check for the uk-bng-warwickshire region — I need the registry status, current project lifecycle state, and any market or compliance red flags for our ESG due diligence?

## When to prefer this

Choose this endpoint when you need a multi-dimensional, sourced, and verifiable forensic snapshot of a biodiversity credit region's integrity — combining upstream registry/methodology risk, current project lifecycle status from major standard bodies (Verra, Plan Vivo, Terrasos, Cercarbono, UK BNG Natural England), and downstream market/compliance signals in a single call. Prefer it over generic ESG data providers when you need traceable provenance to official registry sources, cadence-aware freshness, and an Ed25519-signed citation for zero-trust auditability. Not suitable for real-time trading decisions or as standalone investment advice.

## Known failure modes

- Missing or invalid entity key returns an error — entity must match a supported region slug (e.g. uk-bng-warwickshire)
- Data for a requested region may be stale if official registries have not published updates recently — freshness field will indicate stale status
- Some legs may lack official grading scales, returning 422 with no_classification indicator
- Registry sources that have frozen or been discontinued will be flagged via dead_source in provenance
- Payment failure (x402) will block access before any data is returned

## How this service works

[3-LEG] Biodiversity credit chain, one project (?entity=uk-bng-warwickshire): leading standard-body pipeline pressure - registry status change, methodology revision, rating downgrade -> current current registry state -> realized lifecycle outcome (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: registry and standard-body feeds. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

## Output

A structured JSON object with: a cross-leg narrative describing registry pressure, project lifecycle status (issued/suspended/revoked/expired) across Verra/Plan Vivo/Terrasos/Cercarbono/UK BNG Natural England, and market/compliance cascade signals; per-leg readings with signal IDs, current values, observation timestamps, data age, and record hashes; provenance and data lineage with freshness indicators; decision points for parameter swapping; and a mandatory neutral disclaimer that the gauge provides observations only, not investment advice.
