# SYNTHORA Token Verdict — Base Chain ERC-20 Risk Analyzer

> SYNTHORA Token Verdict — Base Chain ERC-20 Risk Analyzer is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-10-20).

Analyzes an ERC-20 token contract on Base chain and returns a safety verdict (SAFE/UNSAFE/etc.) with rug-pull and honeypot probability estimates and on-chain metrics.

## 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 synthora-token-verdict-base-chain-erc-20-risk-analyzer-b455d4d6 -d '<json body>'
```

Example prompt: Before I buy any of this token, can you run a safety check on Base chain contract 0x4d224452801ACEd8B2F0aebE155379bb5D594381 — I want to know if it's a rug pull or honeypot risk and what the liquidity looks like?

## When to prefer this

Use this endpoint when you need a fast, automated risk assessment of a specific ERC-20 token on the Base chain before trading, investing, or interacting with it. Prefer this over general blockchain explorers when you want a structured SAFE/UNSAFE verdict with probabilistic rug-pull and honeypot scores rather than raw on-chain data. Best suited for DeFi agents, trading bots, or portfolio tools that need a single API call to gate or flag token interactions.

## Known failure modes

- Invalid or non-existent contract address returns error or null result
- Only Base chain is supported — submitting other chains will fail or be ignored
- Probabilities are labeled as prior estimates and may not be well-calibrated for new or obscure tokens
- Tokens with insufficient on-chain history may return zero-values for metrics like age, liquidity, and volume
- Service may be unavailable or return degraded results for very new token contracts

## How this service works

Malla de agentes autónomos sobre infraestructura, modelos de lenguaje y APIs propias. Inteligencia y estudios de mercado operados por la red. Las Palmas de Gran Canaria, España.

## Output

Returns a JSON object with: a verdict string (e.g. SAFE), 30-day rug-pull and honeypot probability scores (0–1), a plain-language summary of the risk assessment, and on-chain metrics including token age in days, liquidity in USD, and 24h trading volume in USD. Probabilities are marked as priors with calibration in progress.
