OneMap Singapore
Add OneMap Singapore to your product for your customers, and give your AI agents governed access to it.
Embed a OneMap Singapore integration so your product can resolve Singapore addresses and locations against the authoritative national map instead of guessing from a general geocoder. OneMap is the Singapore Land Authority's mapping service, and the calls that matter are address and postal code search, reverse geocoding from a coordinate, conversion between the local SVY21 grid and WGS84 latitude and longitude, and routing between two points. Each customer registers and supplies their own OneMap credentials, so lookups run under their own token and allowance rather than a shared key you have to police. fastn owns the token refresh, retries, rate limits and API upkeep, and the same governed connection is what your AI agents use.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers search Singapore addresses and postal codes inside your product using their own OneMap credentials, with no per-customer code.
Reverse geocode a coordinate captured in the field so your product can store a real address rather than a raw point.
Convert between SVY21 and WGS84 coordinates so data captured in local survey terms lines up with the rest of your product.
Look up a route between two points so your product can show travel distance and time without embedding a second mapping service.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent resolves a partial or messy Singapore address before it writes the record, with each lookup logged.
An agent turns a set of coordinates into readable addresses to ground an answer about where something happened.
An agent checks the route between two sites within scoped permissions and reports the distance it returns.
Example prompt
Resolve these five Singapore addresses to postal codes and coordinates, and flag any that do not match a known address.
Set up OneMap Singapore in 4 steps
- 01Enable the OneMap Singapore connector in your fastn dashboard.
- 02Have each customer register for their own OneMap credentials so calls run under their token and allowance.
- 03Map the search, reverse geocode and routing responses to the fields your product stores, per customer.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the OneMap Singapore integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a OneMap Singapore integration without building it. Your customers connect their own OneMap Singapore account inside your product and work their lookups, results and reports there, with no per-customer code on your side.
- Handle the part that actually costs time: these are metered read sources, so an uncached lookup on every page view burns the customer's allowance. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a OneMap Singapore update is not your on-call problem.
- One integration serves your product and your agents. The same governed OneMap Singapore connection powers in-product features and gives AI agents scoped, audited access, so you answer questions from an authoritative outside source without holding that data yourself without wiring it twice.

BoxOneMap Singapore integration FAQ
How do I add a OneMap Singapore integration to my product?
Enable the OneMap Singapore connector in your fastn dashboard, then let each customer authenticate their own OneMap Singapore account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no OneMap Singapore client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own OneMap Singapore account?
Yes. Every connection is scoped to the individual customer, so each authorises their own OneMap Singapore account and only ever sees their own lookups, results and reports. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this OneMap Singapore integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent resolves a partial or messy Singapore address before it writes the record, with each lookup logged.
Who maintains the OneMap Singapore integration?
fastn does. When OneMap Singapore changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Whose credentials does a OneMap Singapore lookup run under?
Each customer's own. Quota and cost land on the customer that caused them rather than on a shared key you have to meter and re-bill, and one heavy customer cannot exhaust another's allowance.
How should OneMap Singapore results be cached?
Per tenant, with a window that matches how fast the underlying data actually moves. OneMap Singapore is a read source rather than a system of record, so the same query returns the same answer until the source changes, and caching is the difference between a sustainable integration and one that exhausts a customer's allowance on a busy page.
What can I build with the OneMap Singapore integration?
A common starting point: search Singapore addresses and postal codes inside your product using their own OneMap credentials, with no per-customer code. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the OneMap Singapore integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding OneMap Singapore does not change your per-connector cost. You can start free with 3 connected accounts.
