How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
Returns a JSON object containing either a newly issued intent checksum (in 'issue' mode) or a verification result indicating whether the proposedAction matches the original intent and complies with the stated policy and authorization (in 'verify' mode). Includes status, checksum string, and any policy violations detected.
Example use cases
Pre-execution agent intent locking
“I'm about to have my agent execute a DeFi swap — can you issue an intent checksum for its stated intent to swap ETH for USDC at market rate, so I can verify the proposed action hasn't drifted before it fires?”
Post-action authorization audit
“My agent just proposed an on-chain action — verify that its proposedAction matches the original intent checksum I issued earlier and confirm the authorization is still valid.”
Policy-bound agent workflow guard
“Issue an intent checksum for my agent's intent to move funds, using a policy that restricts amounts under $500, so I can check later whether its proposed transaction stayed within those bounds.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/devagentpal/human-intent-checksumWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call cryptographic guard for AI agent intent integrity on blockchain workflows — especially when you want to lock in an agent's declared intent before execution and independently verify it hasn't changed. Prefer this over general-purpose signing services when your workflow is specifically about agent authorization policies and blockchain action alignment.
Side effects
- Mismatched intent and proposedAction returns verification failure with mismatch details
- Invalid or malformed intent/policy/authorization object returns 400-level error
- Expired or tampered intentChecksum in verify mode returns invalid checksum error
- Missing required mode field causes request rejection
- Payment not received via x402 protocol returns 402 Payment Required
