Up2Data's /v1 API is a usage-based B2B data API: real-time LinkedIn profile, company, post, and job enrichment, live people, company, job, and post search, Sales Navigator search, and asynchronous batch jobs, all through one X-API-Key header. Every /v1 capability is also batchable as an operation item, not just profile, company, and post enrich. Every call answers a {data, meta} envelope on success or an {error} envelope on failure. Sync enrich, activity, and a profile, company, post, or Sales Navigator batch item bill both when the target is found and when it comes back not found, private, deleted, or unreachable (422 unprocessable_target); every other batch operation refunds a 422 down to 0 once its queue settles. A call is only free when it fails with 400, 401, 402, 429, 500, or 504. Job search bills per job returned; people, company, and post search (Sales Navigator and standard alike) bill per page of up to 25 results, and empty pages are free. The base URL is https://api.up2data.ai/v1. Sync endpoints answer directly, typically in 2 to 8 seconds; submit POST /batch for volume and read results by webhook (batch.completed) or by polling GET /batch/{job_id}.
