Valid, matches Crypto Asset

Every required field is present and each value matches its type. Extra fields are allowed. A field the page does not carry is not guaranteed to come back as null, so check values rather than only checking for null.

  • ✓One call, no parsing code and no second LLM pass
  • ✓The same field names on every request, even when the page layout changes
crypto-asset.ts
// curl -sfLO https://raw.githubusercontent.com/Mozilla-Ocho/tabstack-schemas/main/finance/crypto-asset.json
import Tabstack from '@tabstack/sdk'
import schema from './crypto-asset.json' with { type: 'json' }

const client = new Tabstack() // reads TABSTACK_API_KEY from the environment

try {
  const data = await client.extract.json({
    url: 'https://example.com/investor-relations',
    json_schema: schema,
    effort: 'standard', // 'min' | 'standard' | 'max'
