## Which one, for what

### Brex (C)

Good for: A finance team already on Brex that wants an agent to read expenses and transactions, issue and lock cards, set spend limits, upload receipts and pay vendors.

Ahead on:
- Reliability, 60 against 30

Watch for: The Expenses API update endpoint accepts only `memo`, so an outside agent can't set a category or custom field on an expense through it

### Ramp (C)

Good for: A finance team already on Ramp that wants an agent to read transactions, upload receipts, code and split expenses, issue funds with limits, create bills and work with purchase orders and procurement requests.

Ahead on:
- Schema & documentation, 86 against 80
- Security & auth, 79 against 72
- Maintenance & community, 74 against 66

Watch for: No public status page was found. status.ramp.com doesn't resolve, and no status link appears in the docs, help centre or trust centre pages read

## Verdicts

**Brex.** User tokens carry per-resource scopes with read-only variants, every POST and PUT accepts an `Idempotency-Key`, and ten OpenAPI specs are public. The Expenses API changes only an expense's memo, there is no customer sandbox or official SDK, and the status page logs API errors lasting over four hours on 4 August 2026.

**Ramp.** OAuth 2.0 scopes split read from write across about 40 resources, a 260-operation OpenAPI spec is public, and an audit log endpoint records actions by user and agent. No public status page was found, 89 operations are marked beta, the API Agreement allows changes without notice, and idempotency keys cover only eight write operations.

## Before you call either

### Brex

1. Ask an account admin or card admin for a user token with only the scopes the task needs, and prefer the `.readonly` variants. A token unused for 90 days expires.
2. Send a stored `Idempotency-Key` on every POST and PUT. Create transfer and Create card reject requests without one.
3. Only settled transactions are returned. Poll card and cash transactions with `posted_at_start` and a lookback of at least one day.
4. Keep under 1,000 requests in 60 seconds per client and account, and back off exponentially with jitter on 429.
5. Send only ASCII in free-text fields, and quote the `X-Brex-Trace-Id` response header when reporting an error.

### Ramp

1. Send `scope` on the client credentials token request. Without it Ramp issues a token with no scopes and every resource call fails with 403
2. Follow the full URL in `next` to page. `page_size` defaults to 20 and stops at 100, and the cursor is opaque
3. Stay under 200 requests in any 10 seconds per source IP and back off 1, 2 then 4 seconds on 429. No Retry-After header is documented
4. Don't use `synced_after` or `from_created_at` to find changed records. Bills and transactions have no updated-at filter, so subscribe to webhooks
5. Send `X-Idempotency-Key` when creating funds or procurement requests. Elsewhere a retried POST can create a duplicate, so read back before retrying
