# Promise vs Delivery Reconciliation Gauge (AI/VC/Due-Diligence)

> Promise vs Delivery Reconciliation Gauge (AI/VC/Due-Diligence) 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).

Returns a structured three-leg audit for a named AI product, startup, or VC-backed project: lifecycle status, promise slippage signals, and a quantified promise-vs-actual-delivery gap with cross-validated narrative.

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 promise-vs-delivery-reconciliation-gauge-ai-vc-due-diligence-f4b46bf6
```

Example prompt: Can you pull the promise-vs-delivery reconciliation report for Humane AI Pin — I want to see their lifecycle status, how badly they slipped on timelines and specs, and the gap between what they officially promised and what actually shipped?

## When to prefer this

Choose this endpoint when you need a structured, verifiable audit of whether a specific AI company, hardware product, or VC-backed startup actually delivered on its public promises — especially for due diligence, investment research, or investigative journalism. It is uniquely suited for promise lifecycle tracking (including detecting deleted promise pages) and provides Ed25519-signed citations for offline verification, which generic web search or company databases cannot offer. Prefer this over raw search when you need a pre-reconciled gap metric rather than raw documents.

## Known failure modes

- Entity slug not recognized — returns error or empty legs if the entity key doesn't match a tracked subject
- Stale data — provenance may report 'stale' freshness if official sources haven't updated recently
- No official promise page found — some legs may be missing if the company never published formal commitments
- Data grade warning — response may include 'screening-level, not decision-grade' grade field indicating limited verifiability
- Network or payment failure — x402 payment rejection results in 402 response before data is returned

## How this service works

[3-LEG] Promise-reconciliation chain, one promisor (?entity=humane-ai-pin): leading promise slippage - schedule slipping, spec shrinking, promise page vanishing -> current current company or project status -> realized lifecycle to death or acquisition (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: official announcements and registries. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

## Output

A structured JSON object containing: the entity's lifecycle status (alive/dead/acquired), promise slippage signals (timeline delays, spec reductions, vanished promise pages), a quantified promise-vs-actual delivery gap percentage, a cross-line narrative reconciling official claims against verified delivery records, provenance metadata with data lineage and freshness indicators, and an Ed25519-signed verifiable citation for offline trust verification.
