# Fia Signals ACP Token Safety Check (x402)

> Fia Signals ACP Token Safety Check (x402) is a paid API for AI agents from x402.fiasignals.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns ACP job-create coordinates for pre-swap token safety analysis on a Base/EVM contract, enabling agents to screen for rugpull, honeypot, liquidity, and contract risk before executing a swap or bonding buy.

## 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 x402-fiasignals-com-f54ab7b0 -d '<json body>'
```

Example prompt: Before I swap into 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base, run a Fia Signals token safety check on it and tell me if it's safe, risky, or blocked — I want to see any rugpull, honeypot, or liquidity warnings before I commit.

## When to prefer this

Use this endpoint when an AI agent or trading bot needs to perform a pre-swap token safety check on a Base/EVM contract address and wants ACP-compatible job coordinates as output — particularly before executing a token_swap, bonding buy, or guarded swap. Prefer this over batch endpoints when checking a single token and needing ACP orchestration compatibility. Ideal for agent-to-agent (A2A) commerce pipelines that require structured ACP job metadata downstream.

## Known failure modes

- Invalid or malformed contract address returns a 400-level error
- Contract address not found on Base/EVM returns no-data or unknown verdict
- Payment failure via x402 protocol returns 402 Payment Required
- Rate limiting or quota exhaustion returns 429 Too Many Requests
- Upstream GoPlus or DexScreener data unavailable returns partial or degraded response
- Network timeout on ACP job creation returns 503 or timeout error

## How this service works

Paid x402 bridge to the Fia Signals Virtuals ACP token_safety_check direct-buy packet. Returns ACP job-create coordinates for pre-swap token safety before token_swap, bonding buy, or guarded swap.

## Output

Returns ACP job-create coordinates (job ID, endpoint, and metadata) that the agent can use to retrieve a token safety verdict. The verdict includes a safe/risky/blocked classification, a risk score, contract risk flags, rugpull and honeypot indicators, liquidity and market risk signals, and supporting evidence from GoPlus and DexScreener for the queried Base/EVM token contract.
