Discover, then call

Three requests: read the index, resolve the schema for the surface you need, call the operation with your key.

  1. // Read the index — 2 schemas, 18 tags const index = await fetch("https://ai.tatum.io/api/openapi-index").then(r => r.json())
  2. // Resolve the schema for the surface you care about const schema = await fetch(index.schemas[0].source).then(r => r.json())
  3. // Call the operation — every route takes the same key fetch("https://api.tatum.io/v4/data/wallet/portfolio?chain=ethereum-mainnet", {   headers: { "x-api-key": process.env.TATUM_API_KEY } })

Two surfaces, one contract

Blockchain Data covers reads across chains. Notifications covers webhooks and alerts. Same auth, same base host.

Find the operation, not the docs

Filter by method, tag, or schema. Every row is a live route you can call with the key from the Authentication page.
