# Delx Base ERC-20 Metadata

> Delx Base ERC-20 Metadata is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Fetches ERC-20 token name, symbol, and decimals for a given token contract on the Base blockchain via eth_call for $0.001 USDC per call.

## 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 delx-base-erc-20-metadata-4fe16580 -d '<json body>'
```

Example prompt: What are the name, symbol, and decimals for the ERC-20 token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Choose this endpoint when you need to resolve ERC-20 token metadata (name, symbol, decimals) specifically on the Base L2 network with a simple pay-per-call model via x402 and no API key setup. Prefer it for lightweight, one-off contract lookups in agentic workflows where you want predictable $0.001 per-call pricing without rate-limit management.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty fields
- Contract address not deployed on Base (wrong network) causes eth_call failure
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Network or RPC timeout causes slow or failed response

## How this service works

ERC-20 name/symbol/decimals on Base for $0.001 USDC via eth_call. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

## Output

Returns the ERC-20 token's human-readable name (e.g. 'USD Coin'), ticker symbol (e.g. 'USDC'), and decimal precision (e.g. 6) for the specified contract address on the Base blockchain, sourced via eth_call.
