SuggestAPI is a search platform for teams that need fast autocomplete, typeahead, document indexing, and agent-readable discovery in one stack.

The current product surface includes:

  • Hybrid search that combines lexical FTS with semantic vector retrieval
  • Fast precomputed typeahead suggestions
  • Index creation, schema management, merchandising rules, and blue-green promotion
  • Document ingestion by JSON, CSV, JSONL, Google Shopping feeds, and scheduled integrations
  • Personalization, event tracking, and graph-based recommendations
  • An agent gateway for domain knowledge surfaces, agent workflows, and capability discovery

Core workflow

Most teams use SuggestAPI in a loop:

  1. Create an index.
  2. Define schema and ranking behavior.
  3. Ingest documents or connect a sync source.
  4. Query /v1/autocomplete or /v1/typeahead.
  5. Track clicks, conversions, and personalization events.
  6. Tune ranking, merchandising, and integrations over time.

Main building blocks

  • /v1/autocomplete for full ranked autocomplete
  • /v1/typeahead for low-latency suggestion lookups
  • optional filters, personalization, spell correction, synonyms, and vector search

Data management

  • logical indexes with active physical index promotion
  • inline document ingestion and asynchronous bulk ingestion jobs
  • schema, merchandising, export, reindex, and task endpoints

Integrations

  • Google Shopping feed import
  • webhook ingestion paths for ecommerce and CRM flows

Controls and reporting

  • customer usage summaries and daily usage endpoints
  • API key management with public/private modes
  • billing checkout and portal routes
  • plan, file-size, document-limit, and overage controls

Agent Discovery

  • agent.suggestapi.com/oks/{domain} provides a domain-scoped knowledge surface
  • /v1/agent/* supports agent search, comparison, recommendations, and safe commerce handoffs
  • ARD catalogs let agents discover published capabilities without treating discovery as inventory search
