Overview

Token-lean, verbatim-cited scholarly/web search for agents and apps.

The aptrouter Search API returns verbatim, source-cited results in a token-lean envelope designed for LLM agents — every result carries a quoted sentence and its source identifier, with abbreviated keys to minimise tokens.

Auth: every /v1/* endpoint requires Authorization: Bearer sk_live_…. Keys are issued per customer.

Billing is prepaid. Each search debits 1 credit ($0.005, i.e. $5 per 1,000 searches) from the key’s prepaid balance — there are no plans, tiers, or monthly quotas. When the balance reaches zero the API returns HTTP 402; top up in the dashboard to continue. The X-Credit-Balance response header reports the remaining balance after each call.

Token-lean by design: result keys are abbreviated (d=id, t=title, y=year, a=authors, s=score, q=cited sentence). The X-Token-Budget response header gives an estimated token count so an agent framework can budget without parsing the body.
