Carbon & Cashmere Bittensor Subnet Snapshot API
x402
Carbon & Cashmere Bittensor Subnet Snapshot API is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).
Returns a per-subnet snapshot for any Bittensor mainnet subnet, combining static metadata (modality, owner, burn, kappa, rho) with the latest Tier-A metrics and current alpha-token price.

How this service works
Per-subnet Bittensor snapshot: static metadata (modality/owner/burn/kappa/rho) + latest Tier-A metrics + current alpha-token price. Covers all 129 mainnet subnets.
Output
A JSON snapshot for the requested subnet containing: static metadata fields (modality, owner address, burn rate, kappa, rho), the latest Tier-A performance metrics, and the current alpha-token price. Covers all 129 active mainnet subnets (netuid 0–511 range).
Example use cases
Track alpha-token price for subnet
“What's the current alpha-token price for Bittensor subnet 18? I'm watching it for a potential trade.”
Due diligence on subnet registration
“I'm thinking about registering on Bittensor subnet 21 — can you pull the burn cost, owner, modality, kappa, and rho so I can evaluate it?”
Monitor Tier-A metrics for top subnets
“Grab the latest Tier-A performance metrics for Bittensor subnet 3 so I can compare it against other subnets I'm tracking.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/bittensor-derivatives/subnet/:netuidWhen to prefer
Use this endpoint when you need a complete, single-call snapshot of a specific Bittensor subnet including both its immutable registration parameters and live market data (alpha-token price and Tier-A metrics). Prefer this over general crypto price APIs when the subject is Bittensor subnet-level intelligence rather than top-level TAO price, and over blockchain explorers when you need pre-aggregated Tier-A metrics without raw chain parsing.
Side effects
- Invalid netuid format (non-numeric or out of range) returns a 400 or validation error
- Netuid corresponds to an inactive or non-existent subnet, returning empty or 404 response
- Payment failure via x402 protocol results in 402 Payment Required
- Temporary upstream data unavailability may return stale or partial metrics
- Rate limiting if too many calls are made in quick succession
