# AgenticFi Transaction Summary

> AgenticFi Transaction Summary is a paid API for AI agents from defi-api.agenticfi.wtf, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Fetches a human-readable summary of an on-chain transaction given its hash, including decoded actions, token flows, and context.

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 agenticfi-transaction-summary-3b1817ea
```

Example prompt: Can you summarize what happened in this Ethereum transaction — 0x3a1b2c4d5e6f7890abcdef1234567890abcdef1234567890abcdef1234567890ab — on Base? I want to know what tokens moved and what actions were taken.

## When to prefer this

Use this endpoint when you need to explain or decode what a specific on-chain transaction did — especially for DeFi interactions like swaps, liquidity events, or token transfers — and you have a transaction hash. Prefer over generic block explorers when you need structured, agent-consumable output rather than raw blockchain data.

## Known failure modes

- Invalid or malformed transaction hash returns 400 error
- Transaction not found on the specified chain returns 404
- Chain parameter mismatch — hash exists on Ethereum but base was specified
- Rate limiting or payment failure via x402 returns 402
- Node RPC timeout for very recent or pending transactions

## How this service works

DeFi APIs for AI agents. 36 pay-per-call endpoints for token data, pricing, wallet analytics, swap routing, and on-chain workflows. Powered by x402 on Base.

## Output

A decoded, human-readable summary of the transaction including involved addresses, token flows, swap routes, protocol interactions, and any relevant on-chain events for the given tx hash and chain.
