## 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 agentprovisions-model-provider-delta-d94f5ff0
```

Example prompt: What changes have happened recently in the AI model provider landscape — any new models added, removed, or repriced? Pull the latest provider delta from AgentProvisions so I can update my routing logic.

## When to prefer this

Choose this endpoint when you need a structured, curated diff of what has changed across AI model providers — specifically additions, removals, or updates to model availability. It is distinct from a pricing lookup (use model-pricing-lookup for cost data) and is best suited for agents that need to keep their provider routing or model registry up to date. The x402 micropayment model means you only pay per query, making it suitable for periodic polling without subscription overhead.

## Known failure modes

- Missing or invalid required query parameters return a free 400 error before any payment is charged
- Payment validation failure via x402 returns an appropriate 402 response
- If no changes are detected in the window, the changes array is empty but the call still succeeds and charges
- Stale or unavailable upstream source data may result in incomplete delta coverage

## How this service works

Two x402-paid SKUs (model-provider-delta, model-pricing-lookup) plus free previews, health, and receipt redelivery. Paid routes validate query parameters before the payment gate — invalid/missing required parameters return a free 400, never a charge.

## Output

A JSON object containing the SKU name ('model-provider-delta'), an array of change records describing what shifted across AI model providers (additions, removals, or updates), and a coverage object indicating the honesty/curation scope of the source universe used to compute the delta.
