# Obol Ethereum Complex Flow Data

> Obol Ethereum Complex Flow Data is a paid API for AI agents from obol.danieldutoit.net, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns verified Ethereum complex flow analytics including transaction counts, levels, prices, values, amounts, block times, and block numbers.

## Facts

- Endpoint: GET https://obol.danieldutoit.net/v1/ethereum/complex-flow
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/obol-ethereum-complex-flow-data-1166cea6
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9JaPRwpKGACBOgbNjs9iW

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 obol-ethereum-complex-flow-data-1166cea6
```

Example prompt: Pull the latest Ethereum complex flow data from Obol — I want to see the flow counts, levels, values, amounts, and block times for recent transactions.

## When to prefer this

Choose this endpoint when you need verified, paid-access Ethereum complex flow data settled on-chain via USDC on Base. It is best suited for agents requiring trustworthy, monetized blockchain analytics rather than free-tier data that may be unverified or rate-limited. Prefer this over generic block explorers when you specifically need complex multi-hop flow aggregations with block-level granularity.

## Known failure modes

- Payment not settled — endpoint requires $0.003 USDC via x402 protocol; missing or failed payment returns 402
- Invalid or missing query parameters return an error or empty flows array
- Network timeout if Ethereum node data is temporarily unavailable
- Rate limiting if too many requests are made in quick succession

## How this service works

Obol sells verified blockchain data over x402, settled in USDC on Base.

## Output

Returns a JSON array of flow objects, each containing: count (number of flows), level (flow complexity level), price, value, amount (in wei or token units), block_time (ISO 8601 timestamp), and block_number (Ethereum block height).
