How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response body from Alchemy's Celo Mainnet API is passed through verbatim, along with the original content type header. The agent receives whatever JSON-RPC result, REST response, or error Alchemy returns for the forwarded request.
Example use cases
Check Celo account balance on-chain
“Look up the CELO token balance for wallet address 0xAbC...123 on Celo Mainnet using Alchemy — call eth_getBalance for that address at the latest block.”
Fetch recent Celo transaction history
“Pull the last 10 transactions sent from 0xDef...456 on Celo Mainnet via Alchemy's alchemy_getAssetTransfers endpoint so I can see recent activity.”
Read Celo smart contract state
“Call the Celo Mainnet contract at 0x789...abc using eth_call to read its totalSupply function — I need the current value from Alchemy's RPC.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-celo-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to Alchemy's Celo Mainnet APIs without managing a subscription or API key separately, and when your agent is equipped to handle x402 micropayments in USDC. It is ideal for low-frequency or bursty Celo blockchain queries where a flat subscription is wasteful.
Side effects
- Insufficient USDC balance for x402 payment — gateway returns 402 Payment Required
- Invalid or missing path parameter — upstream returns 400 Bad Request
- Alchemy rate limit exceeded — upstream returns 429 Too Many Requests
- Malformed JSON body — upstream or gateway returns 400 error
- Celo Mainnet node unavailable — upstream returns 503 Service Unavailable
- Invalid Alchemy API key embedded in path — returns 401 Unauthorized
