@sperax/tool-moralis

Cross-chain wallet analytics via Moralis — net worth across seven chains, token balances with prices, realised PnL, and ERC-20 contract metadata.

Moralis is an agent tool from SperaxOS, packaged headless so you can call it from any agent framework. It ships two things: the manifest — a JSON-Schema function definition a model can call — and the executor that runs the call against the real API.

There is no UI layer and no framework lock-in. It works anywhere TypeScript runs.

Install

npm install @sperax/tool-moralis

Usage

Call it directly

import { moralisExecutor } from '@sperax/tool-moralis';

const result = await moralisExecutor.invoke('getWalletNetWorth', {"address":"<address>"}, {
  messageId: 'msg-1',
});

console.log(result.content); // prose summary written for the model to read
console.log(result.state);   // typed data payload for your own UI

Give it to a model

import Anthropic from '@anthropic-ai/sdk';
import { MoralisManifest, moralisExecutor } from '@sperax/tool-moralis';

const client = new Anthropic();

const response = await client.messages.create({
  model: 'claude-opus-4-8',
  max_tokens: 1024,
  messages: [{ role: 'user', content: 'Ask something this tool can answer' }],
  tools: MoralisManifest.api.map((api) => ({
    name: api.name,
    description: api.description,
    input_schema: api.parameters,
  })),
});

for (const block of response.content) {
  if (block.type !== 'tool_use') continue;
  const result = await moralisExecutor.invoke(block.name, block.input, { messageId: response.id });
  console.log(result.content);
}

MoralisManifest.api is already in JSON-Schema form, so it maps onto any tool-calling API — Anthropic, OpenAI, the Vercel AI SDK, or an MCP server — without translation.

Every executor returns a BuiltinToolResult — { success, content, state }. content is prose written for the model to read; state is the typed data payload for your own code. Executors never throw: a failed call comes back as { success: false, content: '<reason>' }, so a network blip degrades the answer instead of crashing the agent loop.

Configuration — required

This tool needs a backend you control. It will not work on a bare npm install alone.

The upstream API requires a secret key. That key is deliberately not bundled here — shipping it in an npm package would leak it to every consumer. Instead the executor calls a SperaxOS /webapi/* route, which holds the key server-side and injects it. That route is session-authenticated, so the public deployment at https://chat.sperax.io (the default origin) answers 401 to anonymous callers.

To use this tool you need one of:

• a SperaxOS deployment of your own, or
• any HTTP endpoint that implements the same request shape and supplies the key.

Point the package at it before importing the tool — the URL is resolved once, when the module first loads:

SPERAX_API_BASE_URL=https://my-speraxos.example.com

or in code:

import { configureSperaxApi } from '@sperax/agent-tools-core';

configureSperaxApi({ baseUrl: 'https://my-speraxos.example.com' });

// import the tool only after configuring, so the path resolves against your origin
const { moralisExecutor } = await import('@sperax/tool-moralis');

Inside a browser that already serves those routes at its own origin, requests stay same-origin and no configuration is needed.

If you want a tool that runs with zero setup, use one of the standalone tools — those call public APIs directly and need no key, no origin, and no backend.

API reference

getWalletNetWorth

Get the total USD net worth of an EVM wallet across every supported chain in one call, with a per-chain breakdown. Spam and unverified contracts are excluded, so this is the most trustworthy single number for "what is this wallet worth". Use this before drilling into a specific chain.

| Parameter | Type | Required | Description | | --- | --- | --- | --- | | address | string | yes | EVM wallet address (0x + 40 hex). |

getWalletTokens

Get token balances for an EVM wallet on one chain, with USD price, USD value and 24h price change per holding, sorted by value. Spam tokens are filtered. Holdings with no available price are counted separately and excluded from the total.

| Parameter | Type | Required | Description | | --- | --- | --- | --- | | address | string | yes | EVM wallet address (0x + 40 hex). | | chain | string | no | Chain to query: ethereum, bsc, polygon, arbitrum, base, optimism or avalanche. Defaults to ethereum. |

getWalletPnL

Get REALISED profit and loss for an EVM wallet on one chain — per-token and aggregate, with average buy/sell prices and trade counts. Realised PnL covers only positions that were sold; it excludes unrealised gains on current holdings and excludes gas costs. Always state that limitation when reporting the result.

| Parameter | Type | Required | Description | | --- | --- | --- | --- | | address | string | yes | EVM wallet address (0x + 40 hex). | | chain | string | no | Chain to query: ethereum, bsc, polygon, arbitrum, base, optimism or avalanche. Defaults to ethereum. |

getTokenMetadata

Get ERC-20 token metadata for a contract address: name, symbol, decimals, total supply, fully diluted valuation, circulating supply, logo, project links, contract verification status, and whether Moralis flags it as possible spam.

| Parameter | Type | Required | Description | | --- | --- | --- | --- | | address | string | yes | ERC-20 token contract address (0x + 40 hex). | | chain | string | no | Chain to query: ethereum, bsc, polygon, arbitrum, base, optimism or avalanche. Defaults to ethereum. |

Types

Shared types come from @sperax/agent-tools-core: BuiltinToolManifest, BuiltinToolResult, BuiltinToolContext, and the BaseExecutor class every tool executor extends.
