It returns native and ERC20 token balances, transfers, approvals, and prices for a wallet, the full decoded transaction history and net worth of an address, and NFT holdings, metadata, owners, trades, and sale prices by wallet, contract, or token. Block and transaction lookups and multi-token price queries let an agent assemble a portfolio or trace activity without running its own node. ## For AI agents Read EVM on-chain data: wallet token balances, transfers, net worth, decoded transaction history, NFT holdings and metadata, and token prices across chains. ## Scope Does not send transactions, custody funds, or deploy contracts. Use for reading EVM wallet, token, and NFT on-chain data only. ## Capabilities - Get native and ERC20 token balances for a wallet address - Retrieve the decoded transaction history and net worth of a wallet - List NFTs held by a wallet and their metadata and trades - Look up NFT owners, traits, and sale prices by contract or token - Fetch ERC20 token prices, metadata, holders, and swaps - Resolve transactions and blocks by hash or number ## Use cases ### AI agent portfolio lookup via Jentic An AI agent connected through Jentic reads a wallet's holdings without running a node or browsing Moralis docs. It searches by intent such as getting token balances, Jentic returns the matching Moralis operation with its input schema, and the agent fetches balances, net worth, and NFTs for an address. The developer's own Jentic One instance injects the API key at call time. Example prompt: Call GET `/wallets/{address}/tokens` for token balances, then GET `/wallets/{address}/net-worth` for the wallet's value ### Wallet activity and history Analytics tools reconstruct what a wallet did. Moralis returns the complete decoded transaction history, native and ERC20 transfers, and approvals for an address, so an agent can trace activity, flag outstanding approvals, and summarize movements without decoding raw logs itself. Example prompt: Call GET `/wallets/{address}/history` for decoded transactions, then GET `/wallets/{address}/approvals` to list ERC20 approvals ### NFT holdings and valuation NFT apps show what a collector owns and what it is worth. Moralis lists NFTs by wallet, returns collection and token metadata, owners, and traits, and reports sale prices by collection or token, so an agent can build a gallery and estimate floor-relative value. Example prompt: Call GET /{address}/nft to list a wallet's NFTs, then GET `/nft/{address}/price` for collection sale prices ### Token price and holder data Dashboards track token prices and distribution. Moralis fetches ERC20 token prices individually or in bulk, returns token metadata by contract or symbol, and reports a holders summary and historical holders, so an agent can price a position and gauge how concentrated a token's ownership is. Example prompt: Call GET `/erc20/{address}/price` for a token price, then GET `/erc20/{tokenAddress}/holders` for its holder summary ## Key endpoints | Method | Path | Description | | --- | --- | --- | | GET | `/wallets/{address}/tokens` | Get token balances with prices by wallet | | GET | `/wallets/{address}/net-worth` | Get wallet net worth | | GET | `/wallets/{address}/history` | Get decoded transaction history of a wallet | | GET | `/{address}/nft` | Get NFTs by wallet address | | GET | `/nft/{address}/price` | Get NFT sale prices by collection | | GET | `/erc20/{address}/price` | Get ERC20 token price | | GET | `/erc20/{tokenAddress}/holders` | Get a holders summary by token address | | GET | `/transaction/{transaction_hash}` | Get transaction by hash | ## Key resources - **Wallets** — Token balances, transfers, approvals, decoded history, and net worth by address - **NFTs** — NFT holdings, metadata, owners, traits, trades, and sale prices - **ERC20 Tokens** — Token prices, metadata, holders, swaps, and owners - **Transactions and Blocks** — Decoded transaction and block lookups by hash or number ## AI readiness This API is usable in Jentic One now. Its AI-readiness score against Jentic's framework shows where it stands today and where improvements would make it even easier for agents to use. - **Score:** 58 / 100 - **Maturity:** Foundational - **Dimensions:** - Foundational Compliance: 45 / 100 - Developer Experience & Jentic Compatibility: 66 / 100 - AI-Readiness & Agent Experience: 51 / 100 - Agent Usability: 80 / 100 - Security: 50 / 100 - AI Discoverability: 78 / 100 - **View full report:** https://jentic.com/apis/moralis.io/moralis/scorecard - **How the score is calculated:** https://docs.jentic.com/reference/api-readiness-framework/overview/ - **More about the dimensions:** https://docs.jentic.com/reference/api-readiness-framework/specification/#dimensional-model-overview ### Score it yourself Every API in the directory is allowlisted, so you can re-score it with no key required. - **Score your own API:** https://jentic.com/scorecard.md - **Scoring CLI agent skill:** https://github.com/jentic/jentic-api-scorecard/blob/main/skills/jentic-api-scorecard/SKILL.md ```sh npx @jentic/api-scorecard-cli score ``` ## Why Jentic - **Setup:** Wiring the Moralis EVM API by hand means learning its X-API-Key header, choosing among more than a hundred read operations across wallets, NFTs, and tokens, and handling chain selection yourself. Through Jentic you install once, import Moralis from the API Directory, store the key once, and your agent calls the data operations it needs. - **Permission scoping:** Moralis puts the wallet or contract address in the URL path (`/wallets/{address}/tokens`), so a rule can pin your agent to read operations on one address. The surface is read-oriented, and you choose which operations it may call, so anything outside the balances and history reads you pick is not reachable unless you add it. - **Credential handling:** Your Moralis API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context. - **Discovery method:** Agents search Jentic by intent such as 'get wallet token balances' or 'list NFTs for a wallet', and Jentic returns the matching Moralis operation with its input schema so the agent calls the right endpoint without browsing the reference docs. ## Related APIs - **Alchemy API** — Alchemy offers node access and enhanced EVM data APIs similar to Moralis's wallet and token endpoints. - **GoldRush Multichain Data API** — GoldRush returns multichain balances, transactions, and NFT data much like the Moralis EVM API. - **CoinGecko API** — CoinGecko provides market-wide token prices and rankings that complement Moralis's on-chain wallet data. - **Tatum Blockchain Data API** — Tatum adds broader multichain operations and transaction building beside Moralis's EVM data reads. ## FAQ ### What authentication does the Moralis EVM API use? The Moralis EVM API authenticates with an API key sent in the X-API-Key header, per its OpenAPI spec. Through Jentic, your key is stored encrypted by your own Jentic One instance and injected into the X-API-Key header at execution time, so it never enters the agent's prompt or logs. ### Can I read a wallet's token balances with the Moralis EVM API? Yes. The wallet operations return native and ERC20 token balances with prices, the complete decoded transaction history, outstanding approvals, and the net worth of an address, so an agent can assemble a portfolio view from a single address. ### What are the rate limits for the Moralis EVM API? The OpenAPI spec does not state numeric rate limits, and usage is typically metered in compute units per plan. Check the Moralis documentation at https://docs.moralis.io for current throughput and compute-unit costs. ### How do I look up NFTs for a wallet through Jentic? Search Jentic by intent such as listing a wallet's NFTs, and it returns the Moralis operation with its input schema. Pass the address, read the holdings, and pull metadata or sale prices, with your key injected at call time. To run it on your own infrastructure, install Jentic One from its GitHub repo. ### Can I limit what my agent is allowed to do with the Moralis EVM API? Yes. Moralis puts the wallet or contract address in the URL path, such as `/wallets/{address}/tokens`, so a rule can pin your agent to read operations on one address so it fetches balances and history and nothing else. The API is read-oriented, and you choose which operations it may call, with every call logged by your self-hosted instance. ### Is there a Moralis EVM API MCP server? You do not need an MCP server to give your agent the Moralis EVM API. Jentic connects it directly from the API Directory: import it, store your key once, and your agent calls the wallet, NFT, and token operations on demand without loading another server's tool definitions into its context.
