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
A paginated list of on-chain transactions matching the specified filters, including transaction hashes, block numbers, sender/receiver addresses, values, categories, and optional metadata. Returns a pageKey for subsequent pagination if more results are available.
Example use cases
Wallet activity audit for compliance
“I need to audit all transactions from wallet 0xDEAD...BEEF on Pharos between block 1000000 and 2000000 — get up to 200 records in ascending order so I can review the full history chronologically.”
Monitoring inbound transfers to a contract
“Fetch all incoming transactions to smart contract address 0x1234...5678 on Pharos, most recent first, up to 50 results, excluding any zero-value transfers.”
Paginating through large transaction history
“I was querying transaction history for address 0xAAAA...BBBB and got a pageKey back — can you fetch the next page of results using that key, keeping the same descending order and metadata included?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/pharos/tx/historyWhen to prefer
Use this endpoint when you need historical transaction data for specific wallet or contract addresses on the Pharos network, especially when filtering by block range, transaction category, or direction. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access without API key setup and want fast, structured JSON output suitable for agent pipelines.
Side effects
- Invalid address format returns a 400 error
- Block range too large may result in timeout or truncated results
- Unknown or unsupported category type returns an error
- Missing required address fields may return an empty result set
- Payment failure (x402) blocks the request before execution
- Invalid pageKey causes pagination to fail or restart
