The API
queryable timechain.

Same data that drives the Grid and the Graph, exposed as a JSON API at api.timechaingrid.com. Free for everyone, with per-key rate limits to keep the service healthy. Sign in with Google or GitHub to mint a key. Heavy users can request lifted limits — no payment, just a stated use case.

Under development

landing in v0.4

The API ships after the Grid and Graph viewers reach parity. Initial endpoints will cover wallet lookup, block activity, lattice keyframes, halving metadata, and a sandboxed Prolog query endpoint.

GET/v1/wallet/{address}

Wallet metadata + lifetime stats.

GET/v1/block/{height}/activity

Coinbase, spenders, recipients, bonds.

GET/v1/lattice/keyframe/{height}

Pre-baked positions at a block height.

GET/v1/halvings

All halvings + projected dates.

POST/v1/query

Sandboxed Prolog queries against the fact base.

Live block height + snapshot age.
