DAO Proposal State Change Checker
x402
DAO Proposal State Change Checker is a paid API for AI agents from api402x.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Cheaply polls whether a DAO governance proposal's on-chain state has changed since the last check, and tells you when it's safe to stop polling.

How this service works
Cheap poll: has this proposal's state changed since you last looked? You pass the state this route or GET /proposal-status gave you last time; it reads the Governor's current state and compares. Call it with no state to get a baseline. One contract read, which is why it is cheap; when it reports changed, buy GET /proposal-status for the new state, its execution_eta and what that means on this contract family. Terminal states (executed, defeated, canceled, expired) never change again -- the response says so explicitly and tells you to stop polling, because charging for a poll that can only ever answer 'unchanged' would be selling nothing. Required: dao and proposal_id. Optional: state.
Output
Returns a JSON object with: dao name, proposal_id, a status field (baseline, unchanged, or changed), the current on-chain state string, a terminal boolean indicating whether this state can ever change again (and if true, advice to stop polling), a checked_at ISO timestamp, an optional next field with recommended action, and an optional detail message with human-readable context.
Example use cases
Automated governance vote watcher
“Keep an eye on Uniswap DAO proposal 456 for me — last time I checked it was in 'Active' state. Let me know the moment it changes, and stop polling once it hits a terminal state like executed or defeated.”
Baseline tracking for new proposal
“I just found out about Aave DAO proposal 789 and want to start tracking it. Can you get a baseline state for it so we know where to compare from going forward?”
Pre-execution transition detection
“Is Compound DAO proposal 55 still in 'Queued' state, or has it moved? I need to know if it's been executed so I can trigger the next step in my workflow.”
Technical details
Endpoint
GEThttps://api402x.com/proposal-state-checkWhen to prefer
Use this endpoint when you need to efficiently monitor a DAO proposal over time without paying for full proposal detail reads on every poll cycle. It costs a single contract read ($0.002 USDC) versus the heavier GET /proposal-status, making it ideal for high-frequency polling loops. Once this endpoint reports terminal=true, it explicitly tells you to stop polling, preventing unnecessary spend. Switch to GET /proposal-status only when this endpoint reports a change and you need the full state details, execution_eta, and contextual interpretation.
Side effects
- Unknown or unsupported DAO name returns an error
- Invalid or non-existent proposal_id returns an error
- Network/RPC issues reading the Governor contract may cause transient failures
- Passing a malformed state string may cause unexpected comparison results
- Payment failure (x402) blocks the request before any chain read occurs
