# Arysphere Base Token Facts Preview

> Arysphere Base Token Facts Preview is a paid API for AI agents from api.arysphere.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Reads raw on-chain facts (name, symbol, decimals, total supply, owner, code size, proxy slots) from a single Base network token contract without producing a grade or safety verdict.

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 arysphere-base-token-facts-preview-0a674580
```

Example prompt: Can you pull the basic on-chain facts for the Base token contract at 0xABC123... — I want to see the name, symbol, total supply, owner address, code size, and whether it uses a proxy slot?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.002 USDC) snapshot of raw on-chain facts for a Base token contract without requiring a full AI-graded verdict. Ideal for pre-screening tokens, verifying metadata, checking proxy patterns, or feeding contract facts into a downstream analysis pipeline. Use it over a full verdict endpoint when you only need objective chain-read data and want to minimize cost and latency.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Contract address is not on Base network (wrong chain)
- Contract does not implement standard ERC-20 functions (no name/symbol/decimals), resulting in missing fields
- Network/RPC timeout causing delayed or failed response
- Rate limiting if called excessively within a short period

## How this service works

Token Quick Check: Base contract facts -- name, supply, owner, code. Not financial advice. A token verdict preview of one Base token contract. Returns: a token verdict preview on one token contract: the contract facts the full verdict reads -- code size, name, symbol, decimals, total supply, owner(), proxy slots -- read from the chain. No grade, no model, no pool price, no holders, no safety or legitimacy call.

## Output

Returns raw on-chain data fields read directly from the Base blockchain for the specified token contract: contract name, symbol, decimals, total supply, owner() address, bytecode/code size, and proxy slot values. No safety grade, no price data, no holder counts, and no AI-generated verdict are included — this is a facts-only preview.
