Bespoke endpoints
One call that answers your question, instead of ten RPC round trips your backend has to stitch together. We design the response shape around your product, not around the node.
Custom APIs on blockchain data
Our public RPC and APIs cover what most teams need. When they do not, we build the endpoint that does: decoded, indexed, aggregated across chains, and served from the same infrastructure we already run for you.
Today
await rpc.getLogs(…)
await rpc.getBlock(…)
await rpc.call(…) // × 200 contracts
// then decode, join, cache, repeat
Your API
const positions = await spectrum.get("/v1/positions");
DecodedIndexedMulti-chainSLA
What we build
Every one of these sits on nodes we own and operate, so the custom layer is not a wrapper around someone else's provider.
Indexed datasets
Contract events, transfers, positions and balances decoded and indexed into a queryable dataset, backfilled from genesis and kept current as new blocks land.
Streams and webhooks
Push instead of poll. We watch the chains for the events you care about and deliver them to your endpoint or queue, with retries and replay when your side is down.
Aggregation across chains
One surface over the 200+ networks we already run, so a multi-chain question stays a single request rather than a fan-out you maintain.
Private deployments
The API can run on dedicated nodes, in your region or in your own environment, when data residency or isolation is a requirement rather than a preference.
Run and owned, or handed over
We operate it under an SLA with monitoring and on-call, or we build it, document it and hand the keys to your team. Both are normal.
How it works
Scope the question
We start from the query your product needs to answer, and work backwards to the data and the endpoint that answers it.
Design the API
Response shape, latency budget, freshness guarantees and failure behaviour, agreed before anyone writes a pipeline.
Build on our nodes
We build against infrastructure we already own and operate, so there is no third-party provider between you and the chain.
Operate it
Monitoring, alerting and an SLA, with the option to hand the whole thing over to your team whenever you want it.
Engineering
Tell us the query you cannot answer
Bring the question your product needs answered. We will tell you what it takes to serve it, and what it would cost to run.
