gov.uk-crime

UK street-level crime around a location from the Home Office data.police.uk service. Give a latitude/longitude (and optional month YYYY-MM, defaults to the latest available — UK data lags ~2 months) and get the total crime count, a breakdown by category (anti-social behaviour, burglary, violent crime, vehicle crime, etc.), and recent individual records (category, approximate street, lat/lon, and outcome status). Free, Open Government Licence (commercial use permitted). Location-risk signal an LLM cannot recall — for property, insurance, and safety agents. Locations are anonymised to nearby map points by the Home Office.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/gov/uk-crime?lat=-90&lng=-180&month=12345&limit=1'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/gov/uk-crime?lat=-90&lng=-180&month=12345&limit=1' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/gov/uk-crime?lat=-90&lng=-180&month=12345&limit=1'
