# NodeFlare Onchain Answer Engine

> NodeFlare Onchain Answer Engine is a paid API for AI agents from rpc.nodeflare.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Answers natural-language questions about any EVM wallet or token across 23 chains, returning a cited verdict synthesized from live on-chain data

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 nodeflare-onchain-answer-engine-e322f455 -d '<json body>'
```

Example prompt: Is the token at 0xabc123... on Zircuit a scam? Check if it's a honeypot, who owns the contract, and whether this wallet 0xdef456... is holding anything suspicious across all supported chains.

## When to prefer this

Choose this endpoint when you need a single, synthesized natural-language answer about wallet or token safety across multiple EVM chains — especially chains omitted by major indexers like Zircuit, Robinhood chain, or Plasma. Prefer it over raw RPC calls or manual contract inspection when you want a cited, human-readable risk verdict without assembling multiple data sources yourself.

## Known failure modes

- Unsupported chain or contract address returns an error or inconclusive verdict
- Ambiguous or malformed natural language question may yield a low-confidence or irrelevant answer
- Very new tokens with minimal on-chain history may produce incomplete analysis
- Network timeouts on newly added or low-traffic chains
- Rate limiting or payment failure (x402) if USDC payment is not properly attached

## How this service works

Onchain Answer Engine: ask a natural-language question about any wallet or token across 23 EVM chains (incl. young chains like Zircuit, Robinhood, Plasma that big indexers omit) and get a cited verdict - 'is this token a scam?', 'what does this wallet hold?' - synthesized from live on-chain data in one call. Built for AI agents.

## Output

A natural-language cited verdict answering the posed question, synthesized from live on-chain data. Includes supporting evidence such as contract ownership details, holder concentration, transfer simulation results, and risk signals — all sourced from the relevant EVM chain(s) in real time.
