Connect PacificCoastAgent ONE closing-cost data to your CRM, transaction desk and reporting stack

PacificCoastAgent ONE (package palmagent.PacificCoastAgent.Two, by PalmAgent) is a city/county-specific closing-cost calculator preloaded with 20+ real-estate calculations. Agents use it to produce seller net sheets, buyer estimates, refinance scenarios and branded reports from a phone or tablet, and it ships a content library for buyer/seller conversations and social marketing. We turn those screens into structured, queryable interfaces using authorized access and documented endpoints.

Seller net sheet API — Programmatic access to net-proceeds line items (sale price, mortgage payoff, commission, title premium, escrow fee, recording fees, transfer taxes, HOA dues, prorations) so a brokerage CRM can attach a fresh net sheet to every listing record.
Buyer estimate API — Down-payment, monthly payment, prepaids and cash-to-close fields for FHA, VA and conventional scenarios; feed them into a loan-officer dashboard or a lead-nurture sequence.
County fee & rate-table export — The city/county rate sets that drive the app, exported as JSON for valuation models, marketing landing pages and analytics.
Report & content-library sync — Generated PDF net sheets and buyer estimates plus the marketing content library, mirrored into a document store or DAM with consistent agent branding.

Feature modules we build for PacificCoastAgent ONE

Each module below names the concrete data it moves and one operational use. We scope only what you ask for, so a first engagement can be a single endpoint rather than the full set.

Account & agent-profile API

Mirrors the app's sign-in and the agent's branding record (name, photo, brokerage, phone, license/NMLS where present, default county). Lets a back office provision teams in bulk and keep report headers consistent across hundreds of saved net sheets.

Net-sheet calculation engine API

Wraps the 20+ calculations — seller net sheet, buyer estimate, refinance, buydown (now with HOA inputs), loan comparison — behind a request/response endpoint. Use it for reconciliation: re-run a stored deal against current county rates and flag drift before the file goes to escrow.

Saved-estimates statement API

Lists a user's saved buyer estimates and seller net sheets with paging, date ranges and status filters, returning the full line-item payload per record. Feeds a pipeline report so a managing broker sees every estimate produced this month and which ones converted to listings.

County rate-table sync

Exports the city/county fee sets (title premium tiers, escrow splits, recording fees, county/city transfer taxes) as versioned JSON. Powers an internal "what does closing cost in this county" widget and keeps a data warehouse table current without re-keying.

Report rendering & delivery API

Generates the branded PDF net sheet or buyer estimate the app already emails, then posts it to a document store or e-mails it through your domain. Use it to auto-attach a net sheet to a CRM opportunity the moment an agent saves one on their phone.

Content-library & compliance feed

Surfaces the marketing content library (buyer/seller talking points, social posts) and the in-app FinCEN alert items as structured entries, so a marketing team can schedule posts and a compliance officer can log when an alert was shown.

Data available for integration (OpenData perspective)

The table below maps the data PacificCoastAgent ONE works with to the screen it comes from, its granularity, and a typical downstream use. Exact field availability depends on whether we work through an official partner API or documented endpoints, and on the customer's authorization scope.

Typical integration scenarios

Five end-to-end examples. Each names the business context, the data or API involved, and how it maps to OpenData / OpenFinance patterns familiar from banking integrations.

1 — Auto-attach a net sheet to every listing

Context: a brokerage wants a current seller net sheet on each listing record in its CRM. Data/API: the Saved-estimates statement API plus the Report rendering API push the line-item payload and PDF when an agent saves an estimate. OpenData mapping: a consented "account information" pull (the agent's saved records) feeding a third-party system — the same shape as an OpenBanking account-transactions feed, applied to closing-cost data.

2 — Loan-officer pre-approval comparison

Context: a mortgage team compares FHA, VA and conventional buyer estimates side by side for a borrower. Data/API: the Buyer estimate API returns cash_to_close, monthly_pi, prepaids and down_payment for each program. OpenData mapping: a "product comparison" call — analogous to OpenFinance product-reference endpoints — that normalises figures across programs for one screen.

3 — County rate warehouse & marketing pages

Context: a title marketing team publishes "closing costs in your county" landing pages and keeps an internal reference table fresh. Data/API: the County rate-table sync emits versioned JSON with effective_date per jurisdiction. OpenData mapping: a reference-data / open-dataset export, polled on a schedule and diffed — the rate-card equivalent of a bank's published fee schedule.

4 — Pipeline & conversion analytics

Context: a managing broker wants to know how many estimates each agent produced and which became listings. Data/API: the Saved-estimates statement API with date-range paging, joined to the CRM on property address and client label. OpenData mapping: periodic batch extraction into a warehouse — an ETL pattern straight out of OpenBanking analytics, here measuring agent activity instead of spend.

5 — Compliance evidence & FinCEN alert log

Context: a compliance officer must show that fee disclosures and FinCEN residential-real-estate notices were surfaced to agents. Data/API: the Content-library & compliance feed returns alert items with acknowledgement timestamps; the Report API archives each net sheet's fee breakdown. OpenData mapping: an immutable event log with consent/acknowledgement records — the audit-trail discipline OpenBanking requires, reused for real-estate settlement.

Technical implementation

We deliver runnable source (Python / Node.js), an OpenAPI specification, a protocol-and-auth flow report, automated tests and operator docs. Below are representative request/response shapes; field names are illustrative and finalised against the live behaviour during analysis.

1) Authenticate & bind an agent session

POST /api/v1/pca-one/auth/token
Content-Type: application/json

{
  "username": "agent@brokerage.com",

  "purchase_price": 720000,
  "down_payment_pct": 10,
  "interest_rate": 6.625,
  "include_hoa": true, "hoa_monthly": 285
}

200 OK
{
  "loan_amount": 648000,
  "monthly_pi": 4149.12,
  "monthly_taxes": 750.00,
  "monthly_insurance": 92.00,
  "prepaids": 3120.40,
  "cash_to_close": 84210.40,
  "rate_table_version": "2026.04.18-CA-San-Diego"
}

4) Webhook: new estimate saved on a device

POST https://yourapp.example/hooks/pca-one
X-PCA-Signature: sha256=<hmac>
Content-Type: application/json

{
  "event": "estimate.created",
  "estimate_id": "be_9920",
  "type": "buyer_estimate",
  "agent_id": "ag_8842",
  "occurred_at": "2026-05-11T15:21:08Z"
}

# Verify HMAC with shared secret, then call
# GET /estimates/be_9920 to pull the full payload.
# Respond 2xx within 5s or the event is retried.

Auth uses short-lived bearer tokens with refresh; list endpoints are paged and rate-limited (honour Retry-After); webhooks are HMAC-signed and retried with backoff; every call is logged with caller, scope and record IDs for the audit trail described under Compliance.

Compliance & privacy

Closing-cost figures sit close to regulated mortgage disclosure. We design integrations to respect that: authorized or documented public access only, data minimization (pull only the fields a use case needs), consent and access logging, and configurable retention. We do not bypass paywalls or authentication, and we label the work as independent of PalmAgent and PacificCoastAgent.

  • RESPA — the Real Estate Settlement Procedures Act governs settlement-cost disclosure and prohibits certain referral arrangements; report exports keep the fee itemisation intact rather than rolling figures into opaque totals. See RESPA on Wikipedia.
  • TRID / TILA-RESPA Integrated Disclosure — the CFPB "Know Before You Owe" rule defines how title and settlement fees appear on the Loan Estimate and Closing Disclosure; we keep owner's and lender's title premiums separable in our payloads. Reference: CFPB TILA-RESPA Integrated Disclosures.
  • FinCEN residential real estate reporting — the app's built-in FinCEN alerts reflect new reporting obligations for certain non-financed residential transfers; our compliance feed captures alert text and acknowledgement so a firm can evidence that staff were notified.
  • State data & consumer-privacy law — for a West Coast / California user base, the CCPA/CPRA framework shapes how client names and property data are stored, shared and deleted; we ship deletion hooks and a data-flow inventory to support those requests.

Data flow / architecture

A typical pipeline has four nodes: (1) PacificCoastAgent ONE client / authorized endpoint(2) Ingestion API & normaliser (auth, paging, schema mapping, HMAC webhook receiver) → (3) Storage (an estimates table, a county rate-table reference set, a document store for PDFs, plus an append-only audit log) → (4) Outputs (your CRM/LOS, a BI dashboard, marketing pages, or a downstream REST API). Sync can be scheduled batch pulls, webhook-driven near-real-time, or both; the normaliser is the single place where field names, currency units and county codes are reconciled.

Market positioning & user profile

PacificCoastAgent ONE is a branded edition of PalmAgent's closing-cost platform — the same family as PalmAgent ONE, FidelityAgent ONE, TicorAgent ONE and ChicagoAgent ONE, typically distributed through a title underwriter to the real-estate agents and loan officers it works with. Primary users are licensed residential real-estate agents, mortgage loan originators and title/escrow marketing representatives, mostly in California and the broader US West Coast, working on iOS and Android phones and tablets in the field. The product is a paid utility — a free 30-day trial, then a low-cost ONE Premium subscription (about $0.99/month or $9.99/year) — and recent releases have leaned into compliance (built-in FinCEN alerts), more accurate scenarios (HOA inputs in the Buydown calculator) and faster, better-organised saved estimates. That mix — fielded mobile use, per-deal calculations, county-specific rate data and a marketing content library — is exactly what makes an OpenData/OpenFinance-style integration layer worthwhile for brokerages and title shops that want this data inside their own systems.

Similar apps & the closing-cost integration landscape

Teams that use PacificCoastAgent ONE often touch other net-sheet and title-tech tools, so a unified closing-cost export usually has to reach beyond a single app. The names below are part of that broader ecosystem; we list them for context, not ranking.

  • PalmAgent ONE — the generic flagship from the same developer; holds the same per-deal net sheets and buyer estimates, so a multi-brand brokerage often wants one schema across PalmAgent and PacificCoastAgent records.
  • FidelityAgent ONE — Fidelity National Title's branded edition with city/county closing-cost data; agents who switch underwriters frequently end up with estimates spread across both apps.
  • TicorAgent ONE — Ticor Title's branded version of the same platform; relevant when consolidating West Coast county rate tables.
  • ChicagoAgent ONE — Chicago Title's calculator; similar net-sheet line items, useful as a cross-check on transfer-tax and recording-fee figures.
  • CTOAgent ONE — another PalmAgent-family branded app; same data model, common in mixed portfolios.
  • TitleCapture — a web platform for title agencies with net-sheet calculators, lead-capture widgets and SSO; integrations often need to merge its estimates with mobile-app records.
  • CostsFirst (First American Title) — desktop and mobile net-sheet/closing-cost tool; firms that use it alongside an agent app want a single reconciled view of fees.
  • Net Sheet Calc — an off-the-shelf branded title-quote app for agents and marketing reps; comparable seller net sheet and buyer cost outputs.
  • TitleTap net sheet calculator — a website-embedded net-sheet widget for title agents; a natural source to sync into the same warehouse table.
  • Qualia — a cloud title/escrow and closing platform (which has absorbed ResWare, RamQuest and E-Closing); downstream of the agent estimate, it's where many of these numbers land for the actual closing.

FAQ

What information do you need to start a PacificCoastAgent ONE integration?

The target app name (provided), the specific data or workflows you need — for example saved seller net sheets, buyer estimates, county fee tables or branded report PDFs — and any account, sandbox or partner credentials you already hold.

How long does delivery take?

A first API drop with documentation typically takes 5 to 15 business days. Real-time webhook pipelines, multi-state rate-table coverage or third-party approvals can extend that timeline.

Is this an official PalmAgent or PacificCoastAgent API?

No. We build integrations through authorized access or documented public endpoints and clearly label the work as independent. Where an official partner API exists we use it; otherwise we deliver protocol analysis and a compatible client you own.

How do you handle compliance and client data?

We follow data minimization, keep consent and access logs, and align with RESPA, the TILA-RESPA Integrated Disclosure rule (TRID) and FinCEN residential real estate reporting. NDAs and on-premise deployment are available on request.
