Your station measures. We witness it.
You already run the sensors: a weather station on a mine, a probe in a paddock, a gauge on a site, a meter on a line. Register a station with Dynamic Feed and every reading it reports comes back as an Ed25519-signed, independently time-stamped, archived station receipt that anyone can re-verify. You bring the coverage; we bring the witnessing and the standing. We do not measure the value, and we say so on every receipt.
Register once, witness every reading.
Register
POST /v1/station/register with a name, location and the quantities it reports. You get a station_id and a provenance descriptor. Your key is stored only as a non-reversible hash.
Report
Your sensor POSTs each reading to /v1/station/reading. Dynamic Feed signs a station-receipt/v1, timestamps it, and archives it append-only.
Verify
Anyone re-verifies the receipt against our published key, no account needed. The receipt states plainly that your station measured the value and Dynamic Feed only witnessed the report.

measured_by: the station operator, not Dynamic Feed
Coverage the world already has.
Dynamic Feed cannot run every sensor on Earth, and it should not try. The world is already covered in stations owned by mines, farms, sites, utilities and community networks. What those stations lack is not measurement, it is standing: a record an adverse party will accept. When your station's readings are witnessed by a neutral third party, signed at the moment and archived so alteration shows up, they stop being your own word and become evidence. You keep operating your sensor exactly as you do now.
A witness, not the measurer.
Dynamic Feed is a neutral witness. A station receipt attests that your station reported this value at a moment and that the signed record has not changed since. It does not claim Dynamic Feed measured the value, that the sensor is calibrated, or that the value is accurate: those remain the station operator's responsibility, and every receipt says so in words. Where an independent source exists, corroborate. We are never in the money path and we never make the decision. Advisory evidence, tamper-evident not tamper-proof, not a certification and not legal advice.
Your sensors. Our receipts.
One call registers a station; one call per reading witnesses it. Self-serve, hash-first on your key, honest on provenance.
