Moralis API
Multi-chain Web3 data platform providing NFT, token, DeFi, and wallet APIs across 20+ blockchains, abstracting away node infrastructure complexity.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Web3/blockchain data API. API key auth. Read-only blockchain data — low write risk. Wallet addresses are pseudonymous PII. HTTPS required. Key rotation recommended.
⚡ Reliability
Best When
You need cross-chain NFT, token, and DeFi data without managing multiple blockchain node providers.
Avoid When
You need to broadcast transactions, require very low-latency data, or need raw RPC control.
Use Cases
- • Fetching NFT ownership and metadata across multiple blockchains
- • Getting DeFi portfolio data including liquidity positions
- • Cross-chain wallet balance and token price lookups
- • Building blockchain data dashboards without running nodes
- • Real-time price feeds for tokens across DEXes
Not For
- • Applications needing raw RPC access to submit transactions
- • Chains not in Moralis's supported network list
- • Very high frequency trading with microsecond data needs
Interface
Authentication
API key in X-API-Key header. Single key per account. Streams (webhooks) use separate authentication with HMAC signature verification.
Pricing
Compute units model similar to Alchemy. Different endpoints cost different CU amounts. Free tier is limited but enough to test integrations.
Agent Metadata
Known Gotchas
- ⚠ Compute unit costs are not always clearly documented per endpoint - agents can exhaust quota faster than expected
- ⚠ NFT metadata is sometimes cached and may be stale for recently minted or updated tokens
- ⚠ Streams (webhooks) require a publicly accessible HTTPS endpoint and HMAC verification
- ⚠ Price data comes from DEX liquidity pools which can be manipulated or have thin liquidity for small tokens
- ⚠ Cross-chain queries require specifying the chain parameter precisely - default is Ethereum mainnet
