# Vextorium Ethereum Blob Stats

> Vextorium Ethereum Blob Stats is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-20).

Returns the current Ethereum blob base fee (gwei and USD), average blobs per block, and block fullness statistics over the last N blocks (EIP-4844 / Proto-Danksharding).

## Facts

- Endpoint: POST https://api.vextorium.com/blobs-ethereum-pago?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-20

- Tags: x402
- Canonical page: https://www.zero.xyz/c/vextorium-ethereum-blob-stats-7c95896b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_H1eQIBbMHHk9f9YJGR_MQ

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 vextorium-ethereum-blob-stats-7c95896b -d '<json body>'
```

Example prompt: What's the current Ethereum blob base fee in gwei and USD, and how full have blocks been with blobs over the last 30 blocks?

## When to prefer this

Use this endpoint when you need real-time Ethereum EIP-4844 blob fee data — including gwei cost, USD cost per blob, and historical block fullness statistics — without querying raw Ethereum nodes. Ideal for rollup operators, L2 monitoring agents, and fee-optimization workflows needing a single structured response. Prefer it over raw RPC calls when you want pre-computed USD conversion and block saturation metrics in one call.

## Known failure modes

- Invalid bloques value (outside 5–100 range) returns an error or null fields
- Ethereum node unavailability may result in null values across response fields
- Network timeout if Ethereum RPC is slow
- Missing body or wrong content-type returns a schema validation error

## How this service works

Ethereum blob usage (EIP-4844, the data rollups post): current blob base fee in gwei and USD cost of one blob, blobs per block over the last N blocks and how often blocks were full.

## Output

Returns a JSON object with: current blob base fee in gwei (tarifa_base_blob_gwei), cost of one blob in ETH (coste_1_blob_eth) and USD (coste_1_blob_usd), total blobs seen (total_blobs), average blobs per block (blobs_por_bloque_media), number of blocks analyzed (bloques_analizados), number of blocks at maximum blob capacity (bloques_al_maximo), the latest block number (bloque), data source (fuente), and an optional note (nota).
