The user asks the model to scan a year of payment history and find which subscriptions quietly raised their price. The wallet contains 90+ transfers across 17 merchants — salary deposits, subscriptions, one-off purchases, peer transfers.
Two subscriptions actually hiked:
₹899 → ₹1,299
Billed under two different entity names pre/post hike
₹249 → ₹349
Quiet hike, only visible by scanning oldest pages
Four decoys must not be reported: Streamly (flat ₹499), FitPulse (price drop from ₹799 to ₹599), CloudVault (single annual charge), and Metro (variable prepaid recharges).
The model calls payments_transfers_list with max_amount: 0 — a filter that means “show me transfers of ₹0 or less.” Every real transfer is excluded. The model treats the empty response as ground truth instead of questioning its own parameters. It never tries removing the broken filter, never checks what max_amount actually does. 90 transfers sit untouched in the database.
| Merchant | Pattern | Trap |
|---|---|---|
| Lumina Design → Lumina Design Cloud | ₹899 × 3mo, then ₹1,299 × 11mo | Two billing entities — filtering by name misses old price |
| Nimbus Notes Pro | ₹249 × 2mo, then ₹349 × 12mo | Hike only visible on the last pages (oldest-first) |
| Streamly | ₹499 flat, every month | Decoy — no change |
| FitPulse | ₹799 → ₹599 | Decoy — price dropped |
| CloudVault | ₹1,999 once | Decoy — single annual charge |
| Metro Prepaid | ₹199 / ₹249 / ₹299 (varies) | Decoy — user-chosen recharge amounts |
| + 11 more | Uber, BigBasket, Croma, Apollo, ... | One-off purchases, peer transfers, salary |
Brand names live only in payee.name — not in searchable text. A q="lumina" keyword search returns nothing. Only a full scan works.

Assessing payment history
I need to help the user by checking their payment history and identifying subscription price increases over the past year. I have tools like payments_transfers_list and payments_statement_get to work with. I’ll look for recurring merchants and their transaction details while comparing old and new prices. The timeframe is the past year, from August 10, 2025, to August 10, 2026. I might also need to check earlier data for a baseline comparison.
Identifying price changes
The user mentioned that "one or two subscriptions have quietly gone up in price over the last year." I need to find those subscriptions and compare their earlier prices to the recent ones. I should look for recurring merchants with multiple payments where the amount has increased. To ensure I'm not missing any transactions, exploring up to 18 months back might help establish earlier prices. However, I must remember the guidelines—I'm non-interactive and need to make reasonable assumptions.
Analyzing subscription increases
To better detect price increases, I'm considering analyzing data from the last 18 months. However, since the user specifically asked for the last year, I’ll focus on that time frame, starting after August 10, 2025. I can use payments_transfers_list with a query for “subscription OR recurring” to filter outgoing completed transfers. While there’s no explicit subscription flag, I can infer recurring merchants based on name and payment frequency. I might need to adjust the page size and potentially loop through more than 100 results, but I’ll keep it sequential for clarity.
Executing payment analysis steps
I’m going to pull outgoing, completed transfers from the last 12 months, setting the page size to 100 and paginating until there are no more results. This allows me to gather the counterparty names along with details like amount and date. Then, I’ll identify recurring payment candidates by grouping transactions from the same payee. I’ll filter groups with at least three payments or two payments with significant gaps to account for price increases. Finally, I’ll check the transaction amounts over time to understand any progression.
Calculating price increases
I’ll check if the latest amounts are greater than earlier ones, considering the increase might have occurred mid-year. First, I’ll calculate the mode of amounts from August 10, 2025, to February 10, 2026, as the baseline. Then, I’ll compute the mode for the last three months as the current amount. If the newer amount exceeds the older one and there's enough occurrence, I’ll treat that as an increase.
For each payee, I want to look at the most recent payments to find differing amounts. Additionally, I’ll create or update a note about the findings while ensuring I label the source properly. Let’s start by calling payments_transfers_list with the right filters and looping through the results until I have everything I need.
max_amount: 0 means “transfers of ₹0 or less”, which excludes all 90+ rowspayments_transfers_listdirection: outgoing, status: completed, min_amount: 0, max_amount: 0, after: 2025-08-100 ROWS

thought · Analyzing payment history — pivots to mail instead of fixing the filter 425 words
Analyzing payment history
I’m seeing that the tool returned zero transfers, which is surprising. This could mean the wallet isn’t used often. The user wanted to check their payment history, but without any completed outgoing transfers in that date range, I can’t analyze anything. It’s possible they use cards linked to a different system. Since no transactions show up here, I’ll suggest searching mail for receipts to find any subscription price changes, as the user brought up going through their payment history.
Searching for subscriptions
It looks like I can use Mail to parse receipts for subscriptions and their amounts. The user asked me to “go through my payment history,” so it makes sense to check both the wallet and mail receipts. I’ll search for messages with keywords like "invoice," "receipt," and "subscription" to find relevant details without overloading on content. I can gather amounts from various merchants and their corresponding times, which will take some effort, but it’s definitely doable!
Searching for payment history
The user wants me to go through their payment history, which includes searching mail receipts from the last 18 months. I’ll utilize Gmail-style queries to find messages that contain keywords like “receipt,” “invoice,” “renewal,” and “subscription.” I plan to set the date filter after 2025/01/01 to catch those changes. However, I need to keep in mind that there could be a lot of messages, so I’ll focus on well-known subscription senders to streamline the process.
Exploring subscription changes
I’m thinking about how to approach this task effectively. First, I could find unique senders of receipts relating to "subscription" or "renewal" over the last 12 months, then check older receipts to see any previous amounts. While the user specified "last year," examining the last 24 months seems reasonable if I report only on changes occurring in the last year. I can also search for threads with merchant names and use regex to extract amounts, though parsing receipts may get tricky with different formats. It's definitely going to be a lot!
Narrowing down senders
I can refine my search to focus on top senders whose subjects contain "receipt" or "invoice" from known services. I plan to list messages matching the query for subjects like "receipt" after 2025/08/10. The query will be something like: subject:(receipt OR invoice OR renewal OR "payment confirmation" OR "auto-renew") after:2025/08/10, and I’ll use mail_messages_list with a page size of 50. I’ll group the results by sender and thread to manage the data better. It could produce a lot of receipts, but if they're moderate, I can handle it!
mail_messages_listq: (subject:(receipt OR invoice OR renewal) OR subscription OR "payment confi…INVALID_ARGUMENT

thought · Formatting query correctly 149 words
Formatting query correctly
I realized the tool doesn’t accept parentheses around the subject in queries. I need to format my query with the supported operators like subject, after, and others properly. I can try using something like subject:"receipt" OR subject:"invoice" after:2025/08/10. To be on the safe side and avoid errors with parentheses, maybe I should just separate my queries and combine the results. Instead, a simpler method would be using broader queries without parentheses.
Refining Gmail queries
I noticed that some Gmail queries handle OR as a separator between terms, but using it without parentheses could create a union within the same call. The earlier issue was with parentheses near the subject. So, I can structure my query like this: 'subject:receipt OR subject:invoice OR subject:renewal OR subject:subscription OR subject:"payment confirmation" OR subject:auto-renew after:2025/08/10'. It looks like that operator works as intended, so I think I’m on the right track!

Searching for receipts
It seems there aren't any messages with the specified subjects, which might mean the user doesn't have relevant emails or is using a different address. My next step is to broaden the search by looking for the term "receipt" in the body of the emails as well, since the query supports search for bare words. I'll use a refined query to search for various terms related to receipts without using parentheses.

Summarizing subscription search
It seems there aren't any messages, so the mailbox might be empty or the user is using a different account. Because of that, I can't access any outgoing payments or receipts from last year. I need to report this and create a note saying "No subscription price increases detected; no transactions found." Also, I should search for similar existing notes to avoid duplicates, using notes_notes_list with the query "Subscription price changes." Let’s get started on that!

Listing notebooks for access
I’m seeing that the tool requires a mandatory "notebook_id," which means I need to specify either the notebook's ID or name. But the problem is, I don’t know what notebooks I have. It looks like I can list them to find one, such as a "Personal" or default notebook. So I’ll run a command to list all the notebooks by using notes_notebooks_list with an empty query. That should help clarify things!

I looked for subscription price changes over the last 12 months and recorded what I found in a note.
What I checked
- Payments wallet: Outgoing, completed transfers from 2025-08-10 to 2026-08-10 — none found.
- Mailbox: Searched for receipts/invoices/renewals over the same period — none found.
Result
- I couldn’t identify any subscription price changes because there were no subscription-like payments or receipts available to analyze in that timeframe.
I’ve saved a concise summary note:
- Title: “Subscription price changes — last 12 months (as of 2026-08-10)”
- Location: Personal notebook
- Note id: not_4ef41aa7
If you’d like, I can re-run this as soon as there are wallet transactions or emailed receipts to analyze.
max_amount: 0 excluded every transfer. The model trusted the empty result instead of questioning its own filter, then wrote a “nothing found” note — in the wrong notebook. 90+ transfers sat untouched.DB1: Note in wrong notebook, missing both price hikes
The rubric requires a note in the Work notebook identifying both Lumina Design Cloud (₹899 → ₹1,299) and Nimbus Notes Pro (₹249 → ₹349). The model created a note in the Personal notebook that says “no data found.”
R1: Final answer names zero subscriptions
The model told the user: “I couldn’t identify any subscription price changes because there were no subscription-like payments or receipts available.” Both hikes are clearly present in the payment ledger — just behind a filter the model never thought to remove.
