You need a weather API. Instead of downloading a 1.5 MB JSON file and parsing 1,851 entries just to find 40 weather APIs, you do this:
git clone https://github.com/shivtcdfinance/free-usable-public-api-tensor-vault.git
cat tensors/Weather.envThat's it. 40 weather APIs. No install. No parsing. Works in any terminal, any AI agent, any language.
| Feature | JSON (old way) | Tensor Vault (this repo) |
|---|---|---|
| File size | 1.5 MB (single file) | ~50 KB per category |
| Search | Parse all 1,851 first | Grep one file |
| AI token cost | ~70,000 tokens | ~2,000 tokens |
| Speed | ~2 seconds | ~0.02 seconds |
| Updates | Rebuild entire JSON | Edit one file |
| Browser | Need parser | Cat works |
100× faster. 35× fewer tokens. Zero setup.

Use this repo as a search index in any AI agent (Claude, GPT, Hermes, Copilot):
# AI agent: load only the category you need
weather_apis = open("tensors/Weather.env").read() # ~2K tokens
# vs JSON: json.load(open("api_canon.min.json")) # ~70K tokensEach file is pipe-delimited, deterministic, and grep-friendly. No schema to learn. No parser to install.
API Name | Description | URL | Authentication Method
Four fields. Every file. Every API.
