## Projects

- [Flare AI Skills](https://kristaps.me/projects/flare-ai-skills/): Agent skills that give AI coding assistants like Cursor, Claude Code, Codex and other coding agents structured domain knowledge of Flare.
- [x402 Weather Insurance Agent](https://kristaps.me/projects/x402-agent/): Parametric rainfall insurance on Flare. An AI agent pays per weather API call with x402. The TEE verifies on-chain FeeCollected before calling OpenWeatherMap.

## Writing

- [What is x402? How I charged a weather API in stablecoins so an AI agent could pay](https://kristaps.me/blog/x402-ai-agent-stablecoin-payments/): x402 turns HTTP 402 into a payment handshake. I used it on Flare so an AI agent could pay per weather API call in an ERC-20, with the API key locked inside a TEE.
