Documented steps
Recognise the deprecation: the Research API at /research/v1 is documented as being deprecated, with a stated deprecation date of 2026-05-01. It still responds today but should not be used for new integrations.
Identify which replacement fits. For a single research question that returns a synthesized structured answer, use POST /search with "type": "deep-reasoning".
For multi-step agentic work with tool use, record enrichment, and run continuation, use the Agent API at POST /agent/runs instead.
Direct swap path: replace the /research/v1 body {instructions, model, outputSchema} with a /search body {query, type: 'deep-reasoning', outputSchema, systemPrompt}.
Move the polling loop: /research/v1 required create-then-poll GET /research/v1/{researchId}; /search with deep-reasoning returns synchronously (12-40s), so replace polling with a longer client timeout.
If you keep the legacy path temporarily, poll GET https://api.exa.ai/research/v1/{researchId} and read status (pending -> running -> completed) plus output.content / output.parsed and citations[].
Update SDK calls: exa.research.create/get/poll_until_finished (Python) and exa.research.create/get/pollUntilFinished (TypeScript) are the legacy surface; the replacement is exa.search(..., type='deep-reasoning').

Known gotchas
The published deprecation date has already passed while the endpoint remains live — treat continued availability as temporary and unsupported, not as a reversal.
deep-reasoning is synchronous and takes 12-40 seconds. Clients with a default 10-30s HTTP timeout will fail on the migrated call unless the timeout is raised.
Pricing changes on migration: deep-reasoning is billed at $15 per 1k requests versus the legacy research task model.
/research/v1 is limited by concurrent tasks (15), not QPS — the replacement /search path is limited to 10 QPS instead, so a burst pattern that worked before may now hit 429.
Documentation for the legacy streaming event names was not published; do not build parsers against unnamed research SSE events.
outputSchema semantics carry over, but deep-reasoning adds synthesis latency on top of the deep-search latency budget.
