## Which one, for what

### Coda (Superhuman Docs) (B)

Good for: Teams whose working data already sits in Coda docs and who want an agent to read and upsert table rows or build docs.

Watch for: Row writes return 202 and take a few seconds to apply, and reads come from a snapshot that can be stale

### Google Sheets API (BB)

Good for: Agents reading and writing cells, formulas and formatting in spreadsheets people already keep in Google Sheets.

Ahead on:
- Reliability, 90 against 81
- Schema & documentation, 83 against 76
- Agent ergonomics, 74 against 61
- Security & auth, 80 against 71
- Payments & pricing, 35 against 30
- Maintenance & community, 85 against 72

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Coda (Superhuman Docs) loses 3 points for them

Watch for: Quotas are 300 reads and 300 writes a minute per project and 60 each per user per project

## Verdicts

**Coda (Superhuman Docs).** API tokens can be limited to one doc or one table and to read or write, and the OpenAPI description covers 125 operations with 429 on almost all. Writes are queued and answered with 202, so each needs a status check. The REST API has no idempotency keys or official client libraries, and the MCP server is in beta.

**Google Sheets API.** Batch updates apply atomically and count as one request, and the drive.file scope limits an app to files the user picks. Quotas are 300 reads and 300 writes a minute per project, reads are by range with no row filter or paging, and a person must complete OAuth consent first.

## Before you call either

### Coda (Superhuman Docs)

1. Poll `/mutationStatus/{requestId}` after every row write. A 202 means queued, and the edit can still fail
2. Send `X-Coda-Doc-Version: latest` when a read must reflect recent edits, and handle the 400 it returns when the snapshot is behind
3. Use `keyColumns` on `POST .../rows` so a retried insert updates the same row instead of adding a duplicate
4. Ask for a token restricted to the one doc or table and to read access where the task allows. An unrestricted token can do anything its owner can
5. Read MCP tool names from the tool list at run time. The vendor says names and parameters can change during the beta

### Google Sheets API

1. Ask for drive.file where the user picks the files. spreadsheets and spreadsheets.readonly are sensitive scopes and need extra verification for a public app
2. Send valueInputOption=USER_ENTERED to write formulas. With RAW the string =1+2 is stored as text
3. Put related changes in one spreadsheets.batchUpdate. It counts as one write request and none of it applies if any request is invalid
4. Pass ranges and a fields mask on spreadsheets.get and leave includeGridData off for large files
5. Back off exponentially on 429 and 503, and keep to one request a second per spreadsheet. After a timeout on values.append, read the range before retrying
