Alchemy API
Blockchain infrastructure platform providing enhanced Ethereum/EVM node RPC access, NFT APIs, token APIs, and real-time event webhooks with best-in-class reliability and developer experience.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API key embedded in URL path is a security concern - keys can appear in server access logs. Dashboard-level domain restrictions help. SOC2 certified. No granular scopes.
⚡ Reliability
Best When
You're building on Ethereum/EVM chains and need reliable node infrastructure plus enhanced NFT/token APIs beyond raw RPC.
Avoid When
You're working on Solana, Cosmos, or other non-EVM chains not supported by Alchemy.
Use Cases
- • Querying on-chain data with enhanced APIs beyond standard JSON-RPC
- • Monitoring wallet activity and smart contract events via webhooks
- • Fetching NFT metadata and ownership data for collections
- • Building blockchain agents that read token balances and transfer history
- • Simulating transactions before sending to detect failures
Not For
- • Non-EVM blockchains outside Alchemy's supported networks
- • Private blockchain or permissioned network access
- • Very high-frequency trading requiring sub-millisecond RPC latency
Interface
Authentication
API key embedded in the RPC URL endpoint. Alchemy Dashboard allows restricting keys by domain and allowed methods.
Pricing
Agent Metadata
Known Gotchas
- ⚠ Compute Unit costs vary by method - getNFTs costs 10x more CUs than eth_blockNumber
- ⚠ Different endpoint URLs needed per network (mainnet, testnet, L2s)
- ⚠ WebSocket connections require separate WSS URLs and reconnection logic
- ⚠ Transaction simulation is not 100% accurate for all smart contract interactions
- ⚠ NFT API responses include spam/suspicious NFTs by default - use excludeFilters
