Machine-first control surface

CertifiedData for AI Agents

The complete execution surface for AI agents: generate certified datasets, log signed decisions, run policy-governed transactions, and verify proof artifacts — all over authenticated HTTP, with Ed25519 on every output.

Quickstart — no auth required

Generate + certify (sandbox)

curl -X POST https://certifieddata.io/api/synth/public/generate \
  -H "Content-Type: application/json" \
  -d '{"templateId":"fraud_detection","rows":100,"engine":"light"}'

Verify any certificate

curl https://certifieddata.io/api/verify \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"cert_id":"scert_xxxx"}'

Sandbox certs carry a scert_ prefix, 7-day TTL, not listed in production registry. Trust boundaries →

Three pillars

Datasets

Generate certified synthetic datasets with Ed25519-signed certificates. Template, prompt, schema, manifest, and upload input modes. Five engine levels from sandbox to DP-CTGAN.

→Template-based generation
→Prompt → spec pipeline
→Schema-controlled output
→Manifest certification
→Notary / attestation

POST /api/synth/public/generate

Decision Ledger

Log tamper-evident AI decisions with Ed25519 signatures and SHA-256 chain links. Public sterilized feed available without auth. EU AI Act Article 12-aligned.

→Create signed decision record
→Chain-linked append-only log
→Public sterilized feed
→Checkpoint verification
→Artifact provenance linking

→Quote a transaction
→Policy evaluation
→Authorization gate
→Signed receipt issuance
→Receipt verification
