How this service works
Returns aggregate EIP-4844 blob economics from Blobscan: average blob fee, blob gas price, blob-as-calldata fee comparison, average blob usage size and totals. Powers autonomous rollup and L2 data-availability agents plus agent-to-agent cost planners deciding when to post blobs versus calldata. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object with ok:true, the niche identifier, and a result object containing: updated_at timestamp, total_blobs count, avg_blob_fee (string), total_blob_fee (string), and total_blob_size (string) — plus provenance showing the upstream Blobscan API source.
Example use cases
Rollup cost optimization decision
“My L2 rollup needs to decide whether to post this batch as blob data or calldata — can you pull the current EIP-4844 blob fee stats and tell me which is cheaper right now?”
Blob gas price monitoring dashboard
“Pull the latest aggregate blob economics from Blobscan — I want the average blob fee, blob gas price, and total blob count so I can update my L2 cost dashboard.”
Agent-to-agent DA cost planning
“Before my autonomous agent posts the next data availability batch, check the current blob fee stats including average blob fee, total fees spent, and blob size averages so it can decide the optimal posting strategy.”
Technical details
Endpoint
POSThttps://eip4844-blob-fee-stats.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when an agent needs aggregate EIP-4844 blob economics in a single call — especially for rollup cost planning, L2 data-availability decision-making, or comparing blob vs calldata costs. Prefer over building custom Blobscan integrations when you need pre-aggregated stats (avg fee, total blobs, total size) rather than per-blob transaction details. Ideal for autonomous agents making real-time posting decisions.
Side effects
- Blobscan API unavailable upstream — may return stale or empty result fields
- updated_at may be empty string if stats have not yet been populated
- Numeric fields returned as strings (e.g. avg_blob_fee:'0') may indicate no data ingested yet
- Payment failure (402) if USDC payment is not properly attached to the x402 request
- Malformed payload may result in error response
