zyfy

Official Python client library for the Zyfy UK data enrichment API.

Two products in one package:

• Vehicle Intelligence — DVLA + DVSA MOT history, ULEZ, tax status, odometer trend, buy recommendation
• Postcode Intelligence — broadband, flood risk, crime, property prices, deprivation, air quality, MP data, and more

Get your API key at zyfy.uk/signup. Full API docs at zyfy.uk/docs.

Installation

pip install zyfy

Requires Python 3.9 or later.

Quickstart

Synchronous

from zyfy import Zyfy

client = Zyfy(api_key="ea_live_...")

# Vehicle lookup
vehicle = client.vehicle.lookup("AB12CDE")
print(vehicle.summary.buy_recommendation)  # "good" | "consider" | "caution" | "avoid"
print(vehicle.signals.mot_expiry_date)
print(vehicle.quota.remaining)             # requests left this month

# Postcode lookup
postcode = client.postcode.lookup("SW1A 2AA")
print(postcode.summary.liveability_level)  # "low" | "medium" | "high"
print(postcode.signals.crime.rate_band)
print(postcode.quota.remaining)

Asynchronous

import asyncio
from zyfy import AsyncZyfy

async def main() -> None:
    async with AsyncZyfy(api_key="ea_live_...") as client:
        vehicle = await client.vehicle.lookup("AB12CDE")
        print(vehicle.summary.buy_recommendation)

        postcode = await client.postcode.lookup("SW1A 2AA")
        print(postcode.signals.crime.rate_band)

asyncio.run(main())

The API key can also be set via the ZYFY_API_KEY environment variable — if it is, you can construct the client with no arguments:

client = Zyfy()               # reads ZYFY_API_KEY
client = AsyncZyfy()          # same

Both clients support context managers for automatic cleanup:

with Zyfy() as client:
    result = client.vehicle.lookup("AB12CDE")

async with AsyncZyfy() as client:
    result = await client.vehicle.lookup("AB12CDE")

Configuration reference

All options are keyword-only. All are optional if ZYFY_API_KEY is set.

Option	Type	Default	Description
api_key	str	ZYFY_API_KEY env var	Your Zyfy API key.
max_enrichment_retries	int	10	Auto-retries when enrichment_pending=True. Each retry waits the Retry-After seconds from the response. Set to 0 to disable.
timeout_ms	int	10000	Per-request timeout in milliseconds. Surfaces as NetworkError on expiry.
base_url	str	https://zyfy.uk/v1	Override for local development or testing.
debug	bool	False	Logs requests and responses via the zyfy logger at DEBUG level. The API key is always redacted.

Full reference

client.vehicle.lookup(registration, *, max_enrichment_retries=None)

Look up a single UK vehicle by registration mark. Returns DVLA details, DVSA MOT history, emissions, and computed intelligence.

Full signal reference: zyfy.uk/docs/vehicle.html

Parameter	Type	Description
registration	str	UK registration mark. Spaces and case are normalised automatically.
max_enrichment_retries	int | None	Per-call override of max_enrichment_retries.

Returns: VehicleResult

---

client.vehicle.bulk_lookup(registrations, *, max_enrichment_retries=None)

Synchronous bulk vehicle lookup. Runs sequentially on the server. Up to your tier's bulk cap per call.

Returns: BulkVehicleResult

Use is_vehicle_bulk_error(item) to distinguish error items from successful results:

from zyfy import Zyfy, is_vehicle_bulk_error

result = client.vehicle.bulk_lookup(["AB12CDE", "NOTREAL"])
for item in result.results:
    if is_vehicle_bulk_error(item):
        print(item.registration, item.error)  # "not_found" | "invalid_format"
    else:
        print(item.registration, item.summary.buy_recommendation if item.summary else None)

---

client.vehicle.submit_bulk(registrations)

Submit an async bulk job. Returns immediately with a job_id. Poll with get_job().

Returns: BulkJobSubmitted

---

client.vehicle.get_job(job_id)

Poll the status of an async bulk job. Check status == "complete" before reading results.

Returns: BulkJobStatus[VehicleResult | VehicleBulkItemError]

status values: "queued" | "processing" | "complete" | "expired"

---

client.vehicle.delete_job(job_id)

Delete a bulk job and its results. Jobs expire automatically after 24 hours.

Returns: DeletedJob

---

client.postcode.lookup(postcode, *, max_enrichment_retries=None)

Look up a single UK postcode. Returns geographic classification, broadband, flood risk, property prices, crime, deprivation, air quality, housing, political, and demographic signals.

Northern Ireland postcodes (BT prefix) are not supported. Raises ValidationError with code="unsupported_region".

Full signal reference: zyfy.uk/docs/postcode.html

Returns: PostcodeResult

---

client.postcode.nearest(lat, lon, *, radius=None, max_enrichment_retries=None)

Find the nearest postcode to a set of WGS84 coordinates. Coordinates must be within the UK bounding box. The response includes a query_point_distance_metres field.

Parameter	Type	Default	Description
lat	float	—	WGS84 latitude.
lon	float	—	WGS84 longitude.
radius	int | None	1000	Search radius in metres. Raises NotFoundError if no postcode centroid is found within the radius.
max_enrichment_retries	int | None	—	Per-call override of max_enrichment_retries.

Returns: PostcodeResult

---

client.postcode.bulk_lookup(postcodes, *, max_enrichment_retries=None)

Synchronous bulk postcode lookup.

Returns: BulkPostcodeResult

Use is_postcode_bulk_error(item) to distinguish errors:

from zyfy import Zyfy, is_postcode_bulk_error

result = client.postcode.bulk_lookup(["SW1A 2AA", "BT1 1AA"])
for item in result.results:
    if is_postcode_bulk_error(item):
        print(item.postcode, item.error)  # "not_found" | "unsupported_region"
    else:
        print(item.postcode, item.summary.liveability_level if item.summary else None)

---

client.postcode.submit_bulk(postcodes) / get_job(job_id) / delete_job(job_id)

Same async bulk pattern as vehicle. submit_bulk returns BulkJobSubmitted, get_job returns BulkJobStatus[PostcodeResult | PostcodeBulkItemError], delete_job returns DeletedJob.

---

Error handling

All errors extend ZyfyError. Import the specific classes for isinstance checks.

import time
from zyfy import (
    Zyfy,
    QuotaExhaustedError,
    RateLimitError,
    ValidationError,
    NotFoundError,
    AuthenticationError,
    ApiError,
    NetworkError,
)

try:
    result = client.vehicle.lookup("AB12CDE")
except QuotaExhaustedError as exc:
    # Monthly quota exhausted. exc.resets is an ISO 8601 UTC string indicating
    # when the quota rolls over — None if no monthly reset applies.
    if exc.resets:
        hours_until_reset = round(exc.retry_after / 3600)
        print(f"Quota exhausted. Resets at {exc.resets} (~{hours_until_reset}h)")
    else:
        print("Quota exhausted. Contact support to increase your limit.")
except RateLimitError as exc:
    # Per-minute rate limit exceeded. Back off by exc.retry_after seconds and retry.
    print(f"Rate limited. Retrying in {exc.retry_after}s")
    time.sleep(exc.retry_after)
    # retry the call...
except ValidationError as exc:
    # Input rejected by the server. exc.code identifies the specific problem.
    # Common codes: "unsupported_region" (BT postcodes), "invalid_format"
    print(f"Validation error: {exc.code}")
except NotFoundError:
    print("Vehicle or postcode not found")
except AuthenticationError:
    print("Invalid or missing API key")
except ApiError as exc:
    print(f"Server error {exc.status_code}")
except NetworkError as exc:
    print(f"Connection failed: {exc.cause}")

Error class	HTTP status	When
AuthenticationError	401	Invalid or missing API key
NotFoundError	404	Vehicle or postcode not found
ValidationError	422	Invalid input; check exc.code (e.g. "unsupported_region", "invalid_format")
RateLimitError	429	Per-minute rate limit exceeded; exc.retry_after seconds until safe to retry
QuotaExhaustedError	429	Monthly quota exhausted; exc.retry_after seconds until reset, exc.resets ISO 8601 datetime (None if not applicable)
ApiError	5xx	Server error; exc.status_code
NetworkError	—	Connection failure or request timeout

All error classes expose raw_body: str with the full response body for debugging.

Quota

Every successful response includes a quota object populated from response headers:

result = client.vehicle.lookup("AB12CDE")
quota = result.quota

print(quota.limit)        # monthly cap — int, or "unlimited"
print(quota.used)         # requests consumed this month
print(quota.remaining)    # requests left — int, or "unlimited"
print(quota.grace_limit)  # buffer above limit before hard block (~10%); None if not applicable
print(quota.resets)       # ISO 8601 UTC string of next reset; None for unlimited plans

remaining reaches zero at the quota limit and further requests are blocked. A small grace buffer (grace_limit) allows a few extra requests above the cap before the hard block kicks in.

resets is None when no monthly cap is in effect. Always check for None before formatting or displaying it.

To avoid hitting the limit unexpectedly in high-volume applications, read quota.remaining after each response and slow down before it reaches zero.

Debug mode

Pass debug=True to log every request and response via the zyfy logger at DEBUG level:

import logging
logging.basicConfig(level=logging.DEBUG)

client = Zyfy(api_key="...", debug=True)

Output looks like:

[zyfy] → GET https://zyfy.uk/v1/vehicle/AB12CDE (X-Api-Key: ea_live_***, attempt 1)
[zyfy] ← 200 (quota-remaining: 9958, retry-after: none)

The API key is always redacted — it will never appear in logs regardless of debug mode. Useful for diagnosing unexpected responses, quota consumption, or enrichment retry behaviour in development.

Enrichment retries

Vehicle lookups may return enrichment_pending=True when background enrichment is still running — typically the first time a registration is seen, or when the vehicle's data is being refreshed. When pending, signals, summary, and scores may be None or incomplete. Postcode lookups are always served from a pre-loaded dataset and never set enrichment_pending.

Automatic retries (default)

The client retries automatically up to max_enrichment_retries times (default: 10), waiting the number of seconds in the Retry-After response header (typically 5 seconds) between each attempt. The final result is returned once enrichment completes or retries are exhausted — no exception is raised either way.

Override the retry limit per call:

result = client.vehicle.lookup("AB12CDE", max_enrichment_retries=3)

Manual retry pattern

If you need control over retry timing — for example, in a task queue where you want to reenqueue rather than block the worker — disable auto-retries and handle enrichment_pending yourself:

import time

client = Zyfy(api_key="...", max_enrichment_retries=0)

result = client.vehicle.lookup("AB12CDE")

if result.enrichment_pending:
    # Partial data returned — signals/summary/scores may be None.
    # The API will typically have the enriched result ready within 5 seconds.

    # Option A: wait and re-query inline
    time.sleep(5)
    result = client.vehicle.lookup("AB12CDE")

    # Option B: in a task queue, store result.registration and resubmit
    # the task after a delay rather than blocking here.

# Use whatever is available — enrichment_pending may still be True
# if enrichment is unusually slow. The data returned is always valid.
if result.enrichment_pending:
    print(f"Partial data for {result.registration} — enrichment still in progress")

recommendation = result.summary.buy_recommendation if result.summary else "pending"
print(result.registration, recommendation)

If auto-retries exhaust while enrichment_pending is still True, the last partial response is returned without raising. All returned fields are valid — only fields that depend on enrichment may be None.
