Sample 3: Quickstart docs, "Tally API" on-chain transfers (fictional)

Overview

Tally API returns ERC-20 transfer history for any address on Base as clean JSON. There are no nodes to run and no log decoding to write.

Quickstart

1. Get a key. Create one in the dashboard. Keys are free for 10,000 requests a month.
2. Make a request.

curl "https://api.tally.example/v1/transfers?address=0xabc...&token=USDC" \
  -H "Authorization: Bearer $TALLY_KEY"

3. Read the response.

{"transfers":[{"hash":"0x...","from":"0x...","to":"0xabc...","amount":"12.50","token":"USDC","block":1234567,"time":"2026-10-21T07:00:00Z"}],"next_cursor":"c_2"}

Concepts

• Amounts are decimal strings already adjusted for token decimals.
• Pagination uses next_cursor. Pass it back as cursor until it is null.
• Finality: transfers appear after 3 confirmations.
