The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_gstin_compliance ~126
The return filing history summarised per return type: filed count, last period filed, months since it, and average filing lag from period end. Facts only — no on-time percentage or defaulter flag is computed; apply your own thresholds, keeping in mind a quarterly (QRMP) filer legitimately shows multi-month gaps.
| Name | Type | Req | Description |
|---|---|---|---|
| financial_year | string | yes | Financial year as YYYY-YY, e.g. 2025-26 |
| gstin | string | yes | 15-character GSTIN, e.g. 27AAPFU0939F1ZV |
No output schema declared.
No examples provided.
get_gstin_filing_preference ~84
Whether the taxpayer files Monthly or Quarterly (QRMP), quarter by quarter, for the given financial year.
| Name | Type | Req | Description |
|---|---|---|---|
| financial_year | string | yes | Financial year as YYYY-YY, e.g. 2025-26 |
| gstin | string | yes | 15-character GSTIN, e.g. 27AAPFU0939F1ZV |
No output schema declared.
No examples provided.
get_gstin_returns ~98
Every GSTR-1 / GSTR-3B (and other type) return a GSTIN filed in the given financial year, with period, filing date, status, and ARN.
| Name | Type | Req | Description |
|---|---|---|---|
| financial_year | string | yes | Financial year as YYYY-YY, e.g. 2025-26 |

get_usage_stats ~27
How many calls this API key has made today. Free — does not consume a credit.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
lookup_hsn_code ~86
The official description for a 2-8 digit HSN (goods) or SAC (services) code, plus the chapter/heading/subheading it sits under. No GST rate is returned — the government's own master publishes no rate column, and a rate depends on more than the code alone.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | 2-8 digit HSN or SAC code |
No output schema declared.
No examples provided.
search_hsn_codes ~90
Find HSN/SAC codes from a free-text description. Exact code matches rank first, then descriptions starting with the term, then descriptions containing it.
| Name | Type | Req | Description |
|---|---|---|---|
| kind | string | – | Restrict to goods (hsn) or services (sac) |
| limit | integer | – | – |
| query | string | yes | Search text, e.g. 'cotton' — at least 2 characters |
No output schema declared.
No examples provided.
verify_gstin ~121
Look up the live GST registration for a GSTIN: legal name, trade name, status, taxpayer type, constitution of business, registration date, and registered address. Every call queries the GST network in real time — nothing is served from a cache. Set include_profile for jurisdiction codes, e-invoicing status, nature of business, and additional places of business at no extra cost.
| Name | Type | Req | Description |
|---|---|---|---|
| gstin | string | yes | 15-character GSTIN, e.g. 27AAPFU0939F1ZV |
