Avoid depending on it in production, and [reach out](mailto:support@getpalm.com) before building on it. Estimate the fees for a formation before submitting — useful for showing cost upfront or for billing reconciliation. Fees are broken down by component (`base`, `dynamic`, `late`, `credit_card`, `ach`); only the components that apply to the jurisdiction are returned. `fee.total` is the all-in grand total assuming credit-card payment (`base + dynamic + late + credit_card`), so you do not have to sum the components yourself. It is always an estimate. **Extra inputs.** Some states price the filing on share count, par value, authorized capital, or member count and need extra query parameters — for LLCs as well as corporations: - `authorized_shares` — required by CT/DE/KY/MA/MI/NM/RI/VA corporations - `par_value` and `par_value_type` — required by DE corporations; `par_value_type` is `par` or `no_par`, and `par_value` is the per-share par value in USD (ignored when `no_par`) - `authorized_capital` — total authorized capital in USD, required by DC/MO corporations - `pages` — document page count, required by DE corporations - `paid_in_capital` — required by IL corporations - `aggregate_par_value` — aggregate par value of all authorized stock (par value × authorized shares) in USD, required by MD corporations - `member_count` — number of LLC members, required by TN LLCs - `startup_for_soldiers` — `true` when the filer qualifies for Missouri’s Startup for Soldiers fee waiver (active-duty military in Missouri forming a new business), required by MO corporations - `expedited_tier` — optional; adds the expedited surcharge for that speed where the state offers expedited processing (tiers seen today: `expedited`, `24_hour`, `same_day`, `3_hour`, `2_hour`, `1_hour`) Any other query parameter is also forwarded to the fee calculation as an extra input, so if a `400` lists a required input not documented here, supply it as a query parameter with that name. Numeric values and `true`/`false` are coerced from the query string automatically. Omit `expedited_tier` and, where the state offers expedited processing, the response includes `expedited_tiers`: a menu of `{ tier, fee }` where `fee` is the added surcharge as an `{ amount, currency }` pair (total cost = the standard fee components + `fee.amount`). Submit your chosen tier on the create endpoint via `expedited_tier`. If required inputs are missing, the endpoint returns `400` listing them. ## OpenAPI ````yaml /api-reference/v1/openapi.json get /v1/filing/formation/fee openapi: 3.0.0 info: title: Palm Partner API description: >- The Palm API is identity verification and compliance infrastructure for US businesses: onboard businesses, verify businesses and people (KYB/KYC) against authoritative sources, monitor them for changes in real time, and act on their behalf through filings, formation, and registered agent services. version: '1.0' contact: name: Palm Support url: https://getpalm.com email: support@getpalm.com termsOfService: https://getpalm.com/terms license: name: Proprietary url: https://getpalm.com/license servers: - url: https://api.getpalm.com description: Production security: [] tags: - name: Registry description: Search business registries - name: Business description: Manage the businesses in your portfolio - name: User description: Manage the people in your portfolio - name: Verification description: Identity and business verification - name: Monitor description: Continuous monitoring of businesses paths: /v1/filing/formation/fee: get: tags: - Filing summary: Get formation fee estimate description: >- > **⚠️ Early access** — This endpoint is in preview and may change in backwards-incompatible ways before it is marked stable.
