A contemporaneous record to defend an AI decision.
When an AI or autonomous system is blamed for a loss, the contested question is what data it was given, and exactly when that data was measured. Dynamic Feed delivers each datapoint as an Ed25519-signed, timestamped record, so the data your system consumed from us can be produced and verified later — evidence, not legal advice.
The call
Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.
# REST (free key)
curl -H "X-API-Key: $KEY" "https://dynamicfeed.ai"
# MCP (keyless) — point any client at https://dynamicfeed.ai/mcp, then call:
Sample response
{ "value": "...", "provenance": { "source": "...", "measured_at": "...Z", "age_seconds": 42 },
"signature": { "alg": "Ed25519", "key_id": "df-ed25519-4cb32e72f333" } }Why live data
Some liability frameworks — notably the EU's revised Product Liability Directive — now let courts presume a defect and causation in complex AI cases where proof is excessively difficult; the presumption is rebuttable. What can help rebut one is a contemporaneous, independent record of the data a system was given at the moment it acted. Dynamic Feed signs every datapoint it serves over its exact bytes, stamps it with source and time, and can anchor the fingerprint to Bitcoin — so the data your system consumed from us can be produced and re-checked, and anyone can verify it hasn't been altered since it was served. This is evidence you can verify; it is not legal advice, and it does not prove a decision was correct.
Use it for
- A signed record of the Dynamic Feed data behind an automated decision
- Defence material if an AI or robot decision is later disputed
- Incident review — show which Dynamic Feed inputs were available, and when
- Pairs with the signed go/caution/no-go verdict trail for embodied AI
FAQ
Does this prove my AI was right?
No. A signature proves the data existed unchanged at a specific time and came from Dynamic Feed — authenticity and integrity. It does not prove the value was objectively true or that acting on it was correct. It is evidence of the inputs, not a verdict on the decision.
Is this legal advice?
No. Dynamic Feed is a data-evidence layer, not a law firm. We provide verifiable records you and your counsel can use; we don't advise on liability.
How is the record kept tamper-evident?
Every datapoint is Ed25519-signed over its exact canonical bytes and written to an append-only archive; change one byte and verification fails. Records can also be anchored to Bitcoin as independent proof they existed by a certain time.
