# Agent402 Coins List

> Agent402 Coins List is a paid API for AI agents from agent402.tools, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a paginated, filterable list of cryptocurrency coins with IDs, symbols, names, and optional contract addresses per blockchain platform

## 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 agent402-coins-list-0cca6c6c
```

Example prompt: Can you get me the coin list filtered to just USDC, including contract addresses across all platforms?

## When to prefer this

Use this endpoint when you need a structured, filterable index of cryptocurrency coins with CoinGecko IDs and optional multi-chain contract addresses, especially when operating in a pay-per-call agent context without API keys. Prefer it over direct CoinGecko API calls when your agent uses x402/MPP payment rails and needs no signup. Best suited for resolving token symbols to IDs or finding on-chain contract addresses across platforms.

## Known failure modes

- Invalid or unknown platform ID returns an empty coins array rather than an error
- Symbol filter is case-insensitive but must be an exact match — partial ticker matches return no results
- perPage values outside 1–500 may be rejected or clamped
- Stale cache may return slightly outdated coin data (fetchedAt timestamp indicates age)
- Payment of 0.005 USDC required per call — insufficient wallet balance results in 402 response

## How this service works

The complete list of tracked coins (~18k) as {id, symbol, name}, paged: `page` + `perPage` (1-500, default 250). `includePlatforms: true` adds each coin's contract address per platform; `platform` (e.g. base, solana, ethereum) keeps only coins with a contract there; `symbol` keeps one ticker (exact, case-insensitive) across all its namesakes. For bulk id resolution, building a local symbol map, or enumerating every token on one chain; for a single lookup use coin-search.

## Output

A JSON object containing a paginated array of coin objects (each with id, name, symbol, and optionally a platforms map of blockchain IDs to contract addresses), plus metadata: total count, current page, total pages, results per page, applied filters, data source (CoinGecko), cache status, and fetch timestamp.
