How this service works
Cybersecurity micropayments API for AI agents — pay-per-call USDC on Base and Solana (x402 v2). Free utility services under /v1/free/* and gateway select under /v1/gateway/* (Public). Paid cybersecurity analysis, CVE/security news feeds, Base blockchain intelligence, network intel utilities, composite domain/URL reports, research, conversion, verification, and feeds. Failed security analyses are not billed (HTTP 503).
Output
Returns a JSON object indicating success status, a tool/resource identifier, an 'ok' status flag, and a human-readable summary of the transaction. May include transaction details such as status, parties involved, amounts, and other on-chain intelligence about the Base blockchain transaction.
Example use cases
Verify a crypto payment on Base
“I just received a payment on Base — can you look up transaction hash 0xabc123def456... and confirm it went through successfully and tell me the amount and status?”
Investigate suspicious on-chain activity
“We flagged a suspicious transaction on Base with hash 0x7f9e2a1b3c4d5e6f... — can you pull the blockchain intelligence on it and summarize what occurred?”
Audit a smart contract interaction
“Can you retrieve the details for Base transaction 0x1d2e3f4a5b6c7d8e... and tell me which contract was called and whether the transaction completed without errors?”

Endpoint
GEThttps://api.speercyberdefense.com/v1/blockchain/tx/%7Bhash%7DWhen to prefer
Choose this endpoint when you need on-chain intelligence about a specific Base blockchain transaction and want cybersecurity-aware analysis alongside standard transaction details. Prefer it over generic block explorers when you need structured JSON output consumable by an AI agent, or when investigating potentially suspicious transactions that may warrant security context. Pay-per-call micropayment model makes it cost-effective for occasional lookups without subscription overhead.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Base network returns not-found error
- Network or RPC connectivity issues may return 503 (not billed)
- Transactions on other chains (not Base) may not be found
