## 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 kairos-signal-depin-developer-velocity-intelligence-5a537ea7
```

Example prompt: Pull the developer velocity data from Kairos Signal for DePIN projects so I can assess how actively these networks are being built and whether development momentum is accelerating or slowing down.

## When to prefer this

Choose this endpoint when you need quantitative developer activity and velocity signals specifically for DePIN (Decentralized Physical Infrastructure Network) projects, particularly for investment due diligence, competitive benchmarking, or research reports. It is especially valuable when you need source-linked data combining developer metrics with economic and capacity context in one call. Prefer this over generic blockchain analytics when the focus is specifically on physical infrastructure decentralization projects.

## Known failure modes

- Missing or invalid payment (x402 payment required at $4.99 USDC per call)
- Malformed properties parameter returns 400-level error
- No data available for queried DePIN project
- Rate limiting or upstream data source unavailability
- Response may be incomplete if source data feeds are delayed

## How this service works
