Documented steps
POST https://api.exa.ai/v0/websets with 'x-api-key'.
Body requires a 'search' object: {"query": "<1-5000 chars describing the entities you want>", "count": <min 1, default 10>}.
Optionally set search.entity to company | person | article | research_paper | custom. Omit it and Exa auto-detects.
Optionally set search.criteria (array of 1-5 {description} objects) for per-item qualification rules; these are auto-detected if omitted.
Add 'enrichments' at create time, or later via POST https://api.exa.ai/v0/websets/{webset}/enrichments with {"description": "<what to find, 1-5000 chars>", "format": "text|date|number|options|email|phone|url"}. When format is 'options', supply 'options' as 1-150 {label} entries.
Set 'externalId' (max 300 chars) to your own identifier so repeat creation is detectable.
Read the 201 response: id, status (idle | pending | running | paused), searches[], enrichments[], monitors[], dashboardUrl.
Poll GET https://api.exa.ai/v0/websets/{id} until status is 'idle', or pass ?expand=items to inline items.
List results with GET https://api.exa.ai/v0/websets/{webset}/items?limit=<1-100, default 20>&cursor=<nextCursor>; page through using {data, hasMore, nextCursor}.
Per item, read properties{}, evaluations[], and enrichments[] where each enrichment result has status pending | completed | canceled plus result[], reasoning, and references[].
To add another search later, POST to /v0/websets/{webset}/searches with 'behavior': 'append' (default) or 'override'.

Known gotchas
Websets is asynchronous. A 201 does not mean results exist — status starts pending/running and items stream in over time.
'idle' is the terminal-ish state to wait for, not 'completed'. The webset status enum is idle | pending | running | paused only.
Reusing an existing externalId returns 409 Conflict. That is the documented dedup mechanism; there is no documented Idempotency-Key header.
Item enrichments complete independently of the webset: an item can exist with enrichment status still 'pending'. Check per-enrichment status before treating a field as empty.
Adding a search with the default behavior 'append' grows the webset; use 'override' deliberately when you intend to replace prior search scope.
Websets bills in credits (roughly 10 credits per fully qualified result), separate from the per-request Search API pricing — budget it independently.
Item listing is capped at 100 per page; always follow nextCursor rather than assuming one page is the full set.
