# Arkham Exchange Tokens List

> Arkham Exchange Tokens List is a paid API for AI agents from api.arkm.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).

## 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 arkham-exchange-tokens-list-f6e606de -d '<json body>'
```

Example prompt: Can you pull up the full list of tokens available to trade on Arkham exchange — both spot and perpetual — so I can see which markets are currently supported?

## When to prefer this

Use this endpoint when you need to discover which tokens are tradable on Arkham exchange before placing orders, building a UI, or resolving a token name to its pricingID for use in other Arkham API calls. Prefer this over scraping the Arkham web interface or hardcoding token lists, as it reflects the live canonical set of supported markets.

## Known failure modes

- Payment failure: x402 USDC payment not included or insufficient — endpoint returns 402 Payment Required
- Authentication error: missing or invalid API key — returns 401 Unauthorized
- Service unavailable: Arkham API downtime — returns 5xx error
- Empty lists: exchange has no tokens listed at query time — returns empty arrays
- Network timeout: slow response if Arkham backend is under load

## How this service works

Get Arkham Exchange tokens. $0.20 per call.

## Output

A JSON object containing two arrays: 'perpTokens' (perpetual futures tokens) and 'spotTokens' (spot market tokens), each element including an 'identifier' object with a 'pricingID' string (e.g. 'bitcoin', 'ethereum', 'solana') used to reference the token in other Arkham API calls.
