How this service works
Mempool Total Size of Transactions by Relative Fee (Sat / vByte) — The total size of transactions waiting in the mempool, denominated in virtual bytes and broken out by relative fee (sat/vByte) cohort. Data by Glassnode.
Output
An array of timestamped objects, each containing a breakdown of the total virtual byte size of unconfirmed Bitcoin transactions grouped by sat/vByte fee rate cohorts, representing a snapshot of mempool congestion levels across different fee tiers.
Example use cases
Example prompt
“Can you pull the latest Glassnode mempool transaction size distribution for BTC in JSON format so I can see how many virtual bytes are queued at each sat/vByte fee cohort?”
Technical details
Endpoint
GEThttps://x402.glassnode.com/v1/metrics/mempool/txs_size_distributionWhen to prefer
Use this endpoint when you need granular, fee-rate-segmented mempool size data from Glassnode specifically — ideal for fee estimation tooling, on-chain analysts, or dashboards that need to understand mempool congestion across multiple sat/vByte tiers rather than just aggregate mempool size. Prefer this over generic blockchain explorers when you need structured, time-series data with fee cohort breakdown.
Side effects
- Missing required 'a' (asset) parameter returns a 400 validation error
- Unsupported asset symbol (non-BTC) returns a 400 or 422 error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Invalid format parameter ('f') returns a 400 error
- Service unavailability or upstream Glassnode data delay causes a 503 or 504 error
