How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a paginated list of Celo transactions matching the specified filters, including transaction hashes, block numbers, sender/receiver addresses, asset types, transfer values, and optional metadata. A pageKey is returned when more results are available for subsequent pagination calls.
Example use cases
Wallet audit for compliance review
“Get me all incoming and outgoing transactions for the Celo wallet 0xDEF...456 from block 10000000 to 12000000, sorted ascending, including metadata, so I can audit its on-chain activity.”
DeFi portfolio transaction tracker
“Fetch the last 100 ERC-20 token transfers sent from my Celo address 0x789...ABC, sorted newest first, and exclude any zero-value transfers.”
On-chain activity monitoring for a dApp
“Retrieve all transactions to the Celo smart contract address 0x111...222 starting from block 15000000, with a max of 25 results, in ascending order, so I can monitor recent user interactions.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/celo/tx/historyWhen to prefer
Choose this endpoint when you need fast, paginated, filterable transaction history specifically on the Celo network, particularly when you need to filter by sender/receiver address, block range, or asset category. Prefer this over generic block explorers when you need structured JSON output suitable for programmatic processing or agent workflows, and when pay-per-call pricing ($0.01 USDC) is preferable to a subscription.
Side effects
- Invalid address format returns an error or empty result
- fromBlock/toBlock values out of range or malformed cause query failure
- Exceeding maxCount limits may truncate results without warning
- Invalid category strings silently ignored or return error
- pageKey from a different query context causes unexpected results
- Network unavailability returns 5xx error
- Payment failure via x402 returns 402 Payment Required
