API-03 · Developer interface family

Geocoding and reverse geocoding

Resolve text or structured addresses to coordinates, and coordinates to address, place and road context.

Know the authority before writing the adapter.

Exact base URLs, authentication, parameters, response fields, quotas, regions and release support are governed by current official Mappls documentation and the entitled OEM program contract.

Synchronous geocoding API

Source authority

Versioned address, place and road index

Degraded behavior

Return unresolved or low-confidence state for ambiguous input; do not promote a guessed address into incident or dispatch authority.

Make every assumption visible at the boundary.

These responsibilities apply before product-specific endpoint and schema details.

Producer responsibilities

  1. Bind the exact application, service, tenant, environment and entitlement before the first call.
  2. Declare region, territory, coordinate order, units, profile and optional feature flags explicitly.
  3. Use bounded timeout, retry and concurrency policy appropriate to read, write or command semantics.
  4. Carry a correlation identifier and idempotency key wherever replay could create duplicate work.
  5. Minimize personal or vehicle data and keep server credentials out of applications, logs and support artifacts.

Consumer responsibilities

  1. Treat missing, unknown, stale, invalid and unavailable as distinct states.
  2. Preserve source, observation time, content or policy version and confidence where the contract supplies them.
  3. Validate schema, entitlement and semantic compatibility before projecting a response into product state.
  4. Do not convert a service response, plan or receipt into a physical, partner or human outcome claim.
  5. Retain only privacy-safe traces needed to reproduce a contracted support or quality issue.

Composes into real product journeys.

The OEM program allocates UI ownership, data rights, service levels and target acceptance for each selected use.

Evidence expected beyond the happy path.

Thresholds and exact tools are program-specific; the evidence categories are not optional.

01

Contract and schema compatibility across supported client and model-year branches

02

Nominal, empty, partial, invalid, stale, throttled, timeout and dependency-failure paths

03

Latency, throughput, burst, quota, backpressure and long-duration behavior

04

Authentication, authorization, tenant isolation, key rotation and revocation

05

Territory, content, profile, entitlement and offline or cache behavior

06

Observability, replay, incident, migration, deprecation and rollback evidence

Documentation, entitlement and release must agree.

The developer guide explains the integration discipline. The current official Mappls documentation and the signed OEM contract remain authoritative for endpoint and product availability.

No universal endpoint promise

Exact base URLs, authentication, parameters, response fields, quotas, regions and release support are governed by current official Mappls documentation and the entitled OEM program contract.
