How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
A list of zero-knowledge proof history records from Giza, each entry likely including proof ID, proof system type (cairo, noir, or risc0), associated agent ID, timestamp, and proof status or metadata. Results are bounded by the specified limit (default 20).
Example use cases
Audit agent ZK proof trail
“Pull up the full proof history for my Giza agent 'agent-0xABCD' — I want to see all proof types and up to 50 entries so I can audit what it's been generating.”
Debug risc0 proof failures
“Get me the last 10 risc0 proofs generated by Giza agent 'agent-0x5678' so I can check if any are missing or malformed.”
Monitor cairo proof output volume
“Fetch the proof history for agent 'agent-0x9999' and filter it to only cairo proofs — show me up to 30 results so I can see how active it's been.”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/giza/getProofHistory?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to retrieve the historical record of ZK proofs generated by a specific Giza agent or across all agents, especially when auditing, debugging, or monitoring proof generation activity. Prefer this over general blockchain explorers when you need Giza-specific proof metadata filtered by proof system type.
Side effects
- Invalid or unknown agentId returns empty results or 404
- Unsupported proofType enum value returns validation error
- Limit value too large may be capped or return partial results
- Payment failure via x402 returns 402 Payment Required
- Service unavailability returns 5xx error
