# Bittensor WeightsSet & Timelocked Weights Activity per Hour

> Bittensor WeightsSet & Timelocked Weights Activity per Hour is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Returns hourly per-validator analytics on Bittensor weight-setting cadence and the post-2025 timelocked commit/reveal anti-frontrun mechanism activity.

## Facts

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 api-carbon-cashmere-de-492e2a33
```

Example prompt: Pull the hourly Bittensor weights-activity data for subnet 1 — I want to see how often validators are setting weights and how much commit/reveal timelocked activity there is under the post-2025 anti-frontrun mechanism.

## When to prefer this

Use this endpoint when you need validator-behavior intelligence specifically around Bittensor weight-setting cadence and the post-2025 timelocked commit/reveal anti-frontrun mechanism. It is the right choice for subnet analysts, validator-performance researchers, and anyone monitoring compliance with the new weight-commit protocol — not for general token prices, staking yields, or metagraph snapshots.

## Known failure modes

- Invalid or unknown netuid returns 400 or empty result
- Out-of-range time window may return no data
- Payment not attached or insufficient USDC results in 402
- Subtensor lite node lag may cause slightly stale data
- Rate limiting if called too frequently without payment

## How this service works

Bittensor WeightsSet + TimelockedWeightsCommitted/Revealed activity per hour. Tracks validator weight-setting cadence and the post-2025 anti-frontrun mechanism. AI agent API for validator-behavior analysts. Informational research data — not investment advice.

## Output

Returns hourly bucketed counts of WeightsSet, TimelockedWeightsCommitted, and TimelockedWeightsRevealed blockchain events, along with per-validator cadence metrics that reveal how actively each validator is participating in weight-setting and the new commit/reveal anti-frontrunning protocol on Bittensor.
