Insured ETH/USD Price Feed Subscription
x402
Insured ETH/USD Price Feed Subscription is a paid API for AI agents from lab.paidapis.net, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Creates a price-insurance subscription that snapshots the ETH/USD oracle price and pays out from an escrow to a subscriber wallet if the price deviates beyond a set tolerance at a future checkpoint.

How this service works
Insured data feed: pay a premium for an ETH/USD price snapshot (?premiumUsdc=, ?maxDeviationPct=, ?checkDelaySeconds=). If the real price has drifted more than your insured tolerance by the checkpoint, claim a 2x refund — a real payout for genuinely stale data, not a fabricated failure.
Output
Returns a subscription record including a unique subscriptionId, the ETH/USD price snapshotted at subscription time, the scheduled checkpoint timestamp, the subscriber wallet address, the premium paid, and the configured deviation tolerance. After the checkpoint, status updates to 'claim-eligible' (deviation exceeded) or 'held'/'refunded', and includes the live ETH/USD price and actual deviation percentage observed.
Example use cases
Short-term ETH price spike protection
“I'm about to execute a large ETH trade and want insurance in case ETH moves more than 1.5% in the next 10 minutes — subscribe me with a 1 USDC premium and use my wallet 0xDEF456... as the payout address.”
Overnight price deviation hedge
“Set up an ETH price insurance for my wallet 0x789GHI... with a 5 USDC premium, a 3% deviation tolerance, and a checkpoint 3600 seconds from now so I'm covered while I sleep.”
x402 escrow pattern experiment
“I'm learning how x402 payment-gated insured feeds work — subscribe with a 0.5 USDC premium, default 1% deviation, 30-second delay, and payout address 0xJKL012....”
Technical details
Endpoint
POSThttps://lab.paidapis.net/api/insured-feed/subscribeWhen to prefer
Choose this endpoint when you want to demonstrate or use an on-chain insurance pattern gated by the x402 micropayment protocol — specifically when the goal is to receive a USDC payout if the ETH/USD price deviates beyond a configurable tolerance at a future checkpoint. Prefer it over generic oracle feeds when you need the escrow-and-payout insurance mechanic, not just price data. Best for DeFi experiments, x402 protocol learning, or lightweight hedging on Base mainnet.
Side effects
- Missing required fields (premiumUsdc or subscriberAddress) returns a 400 validation error
- premiumUsdc exceeding 5 USDC is rejected
- checkDelaySeconds exceeding 3600 is rejected
- Invalid subscriber wallet address format causes rejection
- Payment not included or insufficient USDC via x402 returns HTTP 402
- Oracle price unavailable at snapshot time may cause internal error
