What alerts were in force at your address? Signed.
Whether a hurricane or windstorm deductible applies, and whether damage counts as storm damage at all, often turns on whether an official warning was in force for the area at the time. After the event, both sides argue from screenshots. This page returns a signed, independently re-verifiable receipt of the official alerts currently in force for a US state area, plus the live conditions, and every reading Dynamic Feed serves is archived, so what the record said at time T stays re-checkable. A neutral, timestamped record for the claim file.
The alerts in force for your area, right now.
Enter a US state code and, optionally, a city for the local conditions. Dynamic Feed records the official alerts currently in force for that state area and the live weather, and returns one Ed25519-signed Decision Receipt produced by /v1/answer. Nothing is mocked and nothing is stored about you.

Storm claims are decided on records.
When a claim reaches dispute, the question is rarely whether the roof is damaged; it is whether an official warning covered the area when the damage occurred, because that is what triggers storm deductibles and event definitions in many policies. Screenshots of a weather app do not survive scrutiny. A contemporaneous record from an independent witness, signed at the moment, carrying its source and observation time, and verifiable years later against a published key, is the kind of corroboration both sides can check. Our records work for policyholders and insurers alike: anyone can re-verify them, including the other side.
Evidence, not a coverage determination.
Dynamic Feed is a neutral witness, not an insurer, regulator or adviser. Alerts here are US National Weather Service alerts for a state area, so coverage outside the US and street-level precision are out of scope. This is a live-now receipt: it records the alerts in force at the moment you request it, not a reconstruction of a past date. It does not determine coverage, does not interpret a policy, and policy terms vary by insurer, product and state. Advisory evidence for a claim file, tamper-evident not tamper-proof, zero personal data, and not legal advice.
One API call per claim file.
Claims platforms can mint a signed alerts-in-force receipt the moment a loss is reported, keyless to try, self-serve to scale.
