How to build per-location event ingestion multiple events APIs

The 4-skill bundle on the per-location-event-ingestion agent

One agent. Four coordinated skills. The Ingest + Normalize + Score + Audit bundle runs above the multi-vendor events- API + geo-routing + IANA tz + per-state-DOT + NWS + warehouse substrate and writes one canonical per-location per-event ingestion record.

Compliance overlay

Five anchors run per-location per-event before any event distributes to downstream decision systems. The first anchor is operationally distinctive: multi-vendor events- API ingestion + per-event IANA tz + per-event impact-radius + per-event-class taxonomy + per-event severity + per-vendor DPA + per-source ToS scraping doctrine + per-event-vendor schema-drift + per-event idempotency-fingerprint + per-event idempotent-retry converge on every per-location per-event ingestion decision.

FAQ

What is per-location event ingestion across multiple events APIs — and what is the multi-vendor-events-API-ingestion-times, per-event-IANA-tz-times, per-event-impact-radius-times, per-event-class-taxonomy-times-per-vendor-DPA-scraping-doctrine-times, per-event-idempotency-fingerprint problem distinctive to this skill?

A multi-location operator with 50-300 stores ships per-location per-event ingestion across 10-25 multi-vendor events APIs (Eventbrite + Meetup + Ticketmaster + Bandsintown + Songkick + Eventful + AllEvents + Stubhub + SeatGeek + Vivid Seats + TickPick + Goldstar + Cvent + Bizzabo + Hopin + Airmeet + Whova + Eventcombo + Pollen + per-municipality events.gov + per-county event calendar + per-school district academic calendar + per-public-library events + per-state-DOT traffic events + per-NWS National Weather Service + NOAA + per-faith-community + per-civic-association + per-vertical industry-event). Per-week per-portfolio: 10,000-100,000 per-location per-event signals requiring normalization + impact-radius computation + per-event-class taxonomy + severity scoring. The four-skill bundle on the per-location-event-ingestion agent — Ingest, Normalize, Score, Audit — sits above the multi-vendor events-API + geo-routing + IANA tz + per-state-DOT + NWS + warehouse substrate and writes a per-location per-event canonical ingestion record. The operationally distinctive anchor: per-location per-event ingestion across multi-vendor events-APIs (Eventbrite + Meetup + Ticketmaster + Bandsintown + Songkick + AllEvents + Stubhub + SeatGeek + Cvent + Bizzabo + Hopin + per-municipality events.gov + per-county + per-school district + per-public-library + per-state-DOT + per-NWS + per-NOAA + per-faith-community + per-civic-association + per-vertical industry-event) + per-event normalization (per-event IANA tz database + per-event DST + per-event lat/lon geocoding + per-event geo-fence + per-event capacity + per-event age-rating + per-event ticket-tier + per-event ADA-accessibility + per-event language + per-event ticket-price-range + per-event sold-out) + per-event impact-radius computation (drive-time isochrone 5/10/15/30-min + walk-time 5/10-min + transit-time 15/30-min) + per-event-class taxonomy (concert + festival + sports + conference + community + family + religious + civic + cultural + sales + recall + weather + traffic + safety + emergency + school + church + government + per-vertical) + per-event severity classification (P0 emergency + severe-weather + recall + P1 large-attendance + P2 medium + P3 small + P4 docs-only) + per-event consent (per-vendor DPA + per-source ToS scraping doctrine (hiQ Labs + Van Buren + Meta v Bright Data) + per-API rate-limit + per-vendor LLM zero-retention) + per-event-vendor schema-drift detection + per-event idempotency-fingerprint (canonical-hash + SHA-256 + Blake3 + xxHash + composite-business-key per-vendor-event-id) + per-event idempotent-retry (exponential backoff + jitter + Conflict 409 + 429 + 503 + circuit-breaker + DLQ).

Why do Eventbrite + Meetup + Ticketmaster + Bandsintown + Cvent + Hopin + per-municipality events.gov + per-NWS + Esri + MapBox break at multi-location-25-vendor-multi-jurisdiction scale?

Each events-API + geo-routing + IANA tz vendor ships per-account flat event-primitive at single-vendor level. None coordinates per-location per-event ingestion across 10-25 multi-vendor events-APIs + per-event IANA tz normalization + per-event impact-radius computation + per-event-class taxonomy + per-event severity scoring + per-vendor DPA + per-source ToS scraping doctrine + per-event idempotency-fingerprint + per-event idempotent-retry. None handles per-municipality events.gov + per-county + per-school district + per-public-library + per-state-DOT + per-NWS + per-NOAA + per-faith-community + per-civic-association + per-vertical industry-event coverage simultaneously. None gates against FDD Item 19 financial performance representations when event-impact shared with franchisees + FINRA Rule 2210 + SOX 302/404/906 + FASB ASC 280. None writes a per-location per-event WORM ingestion audit trail. The four-skill bundle Ingest + Normalize + Score + Audit sits above the multi-vendor events-API + geo-routing + IANA tz + per-state-DOT + NWS + warehouse substrate — it does not replace it.

How does Ingest + Normalize work?

Ingest runs per-vendor per-location per-day events-API ingestion across Eventbrite + Meetup + Ticketmaster + Bandsintown + Songkick + Eventful + AllEvents + Stubhub + SeatGeek + Vivid Seats + TickPick + Goldstar + Cvent + Bizzabo + Hopin + Airmeet + Whova + Eventcombo + per-municipality events.gov + per-county + per-school district + per-public-library + per-state-DOT traffic + per-NWS NOAA + per-faith-community + per-civic-association + per-vertical industry-event. Per-vendor DPA + per-API rate-limit + per-source ToS scraping doctrine compliance (hiQ Labs v LinkedIn + Van Buren v United States + Meta v Bright Data). Per-vendor schema-drift detection (per-vendor schema versioning + per-vendor schema evolution + per-vendor contract-test via Pact + Spring Cloud Contract). Per-event idempotency-fingerprint generation (canonical-hash + SHA-256 + Blake3 + xxHash + composite-business-key per-vendor-event-id). Per-event idempotent-retry (exponential backoff + jitter + Conflict 409 + 429 + 503 + circuit-breaker + DLQ). Normalize runs per-event normalization: per-event IANA tz database time-zone resolution + per-event DST handling + per-event lat/lon geocoding via Esri ArcGIS + MapBox + Foursquare + SafeGraph + Placer.ai. Per-event geo-fence + per-event capacity + per-event age-rating + per-event ticket-tier + per-event ADA-accessibility flag + per-event language + per-event ticket-price-range + per-event sold-out flag. Per-event canonical schema.

What does Score + Audit do?

Score runs per-location per-event impact-radius computation: drive-time isochrone 5/10/15/30-min + walk-time isochrone 5/10-min + transit-time isochrone 15/30-min via Esri ArcGIS + MapBox + OpenRouteService + OSRM + Valhalla + HERE Maps + Google Maps API + TomTom. Per-event-class taxonomy classification (concert + festival + sports + conference + community + family + religious + civic + cultural + sales + recall + weather + traffic + safety + emergency + school + church + government + per-vertical). Per-event severity classification: P0 emergency + severe-weather alert + recall-event (immediate alert + per-franchisor escalation) + P1 large-attendance per-vertical-relevant event 72-hour + P2 medium-attendance 7-day + P3 small-attendance 30-day + P4 docs-only. Gate runs 5 anchors per-location per-event before any event distributes to downstream decision systems. (1) Multi-vendor events-API ingestion + per-event IANA tz normalization + per-event impact-radius + per-event-class taxonomy + per-event severity + per-vendor DPA + per-source ToS scraping doctrine + per-event-vendor schema-drift detection + per-event idempotency-fingerprint + per-event idempotent-retry.

What does the 6-workstream pre-engagement-baseline reporting cycle look like for this skill?

Every two weeks during the Tier 3 Fractional Digital Marketing Lead engagement, six workstreams report against the pre-engagement baseline. Workstream 1: per-portfolio per-location per-event per-period event-ingestion coverage — locations covered + events-API vendors integrated + per-municipality/county/school-district/state-DOT/NWS sources absorbed + per-event normalized. Workstream 2: Ingest per-vendor per-location per-day events-API ingestion flow — per-vendor DPA + rate-limit + ToS scraping doctrine + idempotency-fingerprint + idempotent-retry + per-vendor schema-drift detection. Workstream 3: Normalize per-event normalization flow — per-event IANA tz + DST + lat/lon + geo-fence + capacity + age-rating + ticket-tier + ADA-accessibility + language + price-range + sold-out. Workstream 4: Score per-location per-event impact-radius + per-event-class taxonomy + per-event severity flow. Workstream 5: Regulatory-defense audit coverage — multi-vendor events-API + IANA tz + impact-radius + taxonomy + severity + DPA + scraping doctrine + idempotency-fingerprint + EU AI Act Article 50 + FDD Item 19 + FINRA + SOX + FASB ASC 280. Workstream 6: FBC feedback-loop pattern-learning — per-event realized-vs-predicted impact + per-vendor schema-drift retrospective + per-event severity-classification retrospective.
