EVIDIQ Cadence

The other sixteen services answer questions.

Cadence answers them again when tomorrow arrives.

Durable, attested future execution for agents. 18 tools (8 free, 10 paid) that schedule one-shot, recurring, retry-ladder, expiration, standing-monitor, and workflow jobs — and hand back an EIP-191 receipt for every firing, with 0G-anchored attestations. AI agents don't have a future; Cadence sells time as a service.

What Cadence is for

Durable Scheduling

One-shot, recurring (interval/cron), retry ladders, and expirations with lead time — jobs survive restarts in SQLite on a mounted volume.

Standing Monitors

Recurring call to any target MCP tool plus a condition; fires only when the condition trips.

Workflow Chains

Ordered steps, each with its own deadline; a missed deadline fires an escalation instead of stalling.

EIP-191 Receipts

Every firing carries a signed receipt over a closed field set plus an idempotency key — at-least-once, never exactly-once, never early.

Attestation

attest_execution bundles a job's whole firing history into a signed attestation anchored on 0G Storage.

Free Lifecycle

pause_job and cancel_job cost nothing; a cancelled or expired job is a terminal state with a receipt — silence is never an outcome.

Eighteen MCP tools

Eight free tools support discovery, validation, and the lifecycle. Ten paid tools put future work on the clock.
