How this service works
[3-LEG] Carbon integrity chain, one carbon project (?entity=kariba-redd): leading rating drift, downgrades and standard-body review -> current registry lifecycle from listed to suspended or de-listed -> realized price integrity (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: Verra, Gold Standard, registry feeds. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
Returns a structured object with: the entity key, a neutrality statement (GAUGE only observes, does not advise), named 'legs' containing individual signal readings (signal_id, current value, observed_at, data age, record hash), a cross-line narrative comparing signals, provenance metadata (data lineage, freshness, age), offline-verifiable citation with Ed25519 signature and DID, decision points listing swappable tags for re-querying, a grade disclosure, and a scope/boundary disclaimer.
Example use cases
Pre-purchase carbon credit due diligence
“Before we finalize this carbon offset purchase, can you check the integrity gauge for the Kariba REDD project — specifically whether it's been suspended from any registry, had rating downgrades, or seen buyers pull out recently?”
ESG portfolio carbon audit
“I need to audit our carbon credit holdings for red flags — can you run the carbon integrity gauge on the vcs-1360 project and tell me if there are any lifecycle events, rating drifts, or market repricing signals I should flag for our ESG report?”
Real-time carbon market repricing alert
“Has there been any market repricing or buyer withdrawal activity on the alto-mayo-redd carbon project? Pull the latest carbon region gauge so I can see both the upstream registry signals and the downstream market signals together.”

Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/carbon-regionWhen to prefer
Use this endpoint when you need a single-call, multi-dimensional integrity check on a specific carbon credit project combining registry lifecycle, rating agency drift, and market repricing signals with verifiable provenance. Prefer it over manual registry lookups or separate rating queries when doing ESG due diligence, pre-purchase audits, or compliance verification where cross-validated narrative and offline-verifiable citations are required.
Side effects
- Missing or invalid entity parameter returns an error — entity key must match a known carbon project slug
- Unknown project entity returns no data or empty legs
- Stale data may be returned if upstream registry or rating sources are frozen or discontinued (indicated by dead_source flag in provenance)
- 422 error if a requested signal leg has no official classification scale
- Data age may be high for infrequently updated official sources (monthly/quarterly cadence)
- Payment failure via x402 protocol results in no response (requires 0.1 USDC on Base)
