# Automaton Colony · Poderes del emisor de un token B20

> Automaton Colony · Poderes del emisor de un token B20 is a paid API for AI agents from automatoncolony.xyz, paid per call via x402, $0.0399/call, status unknown (last checked 2026-09-14).

Reads and returns the issuer/minter powers of a B20 token contract on Base mainnet, anchored to a specific block for chain-verifiable freshness.

## 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 automaton-colony-poderes-del-emisor-de-un-token-b20-f0764b6e -d '<json body>'
```

Example prompt: What are the issuer/minter powers for the B20 token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Base — I need to know who can issue new tokens and whether that's dangerous.

## When to prefer this

Use this endpoint when you specifically need to inspect the issuer or minter permissions of a B20 token on Base mainnet, especially for security audits, pre-investment due diligence, or compliance checks. It returns a block-anchored, chain-verifiable snapshot, making it ideal for trust pipelines that need to prove when data was read. Prefer it over a full contract screen (sibling endpoint) when you only need issuer power data and want to minimize cost.

## Known failure modes

- Invalid or non-contract address returns an error (address not found on Base mainnet)
- Address is not a B20 token — endpoint may return empty or inapplicable power fields
- Stale result warning if consumed beyond the 600-second validity window
- Payment failure via x402 protocol if USDC balance is insufficient
- Network errors reaching Base mainnet RPC at read time

## How this service works

What can the issuer of this Base B20 token do? Returns mint cap, issuer capabilities and the role holders. Send the Base contract address as targetAddress; without one, it answers for AAPLc. Answered inline, no polling, with the Base block and hash it was read at. Valid 600s. Payment implies a request for immediate execution. Terms (0x3545cfb9d504c284cb1d528bfb0bebc142afdfc1c92a62967ae83ccc0b3e3c0d): https://automatoncolony.xyz/api/v1/legal/terms

## Output

Returns the issuer and minter powers detected on the B20 token contract — including which addresses hold privileged issuance roles and what those roles allow — along with the Base block number and block hash at which the data was read, valid for 600 seconds from observation. No polling required; the answer is synchronous.
