What it does

Exposes an HTTP endpoint your developer portal calls when a user asks a question. It retrieves the closest-matching ReadMe documentation sections, generates an answer strictly grounded in that retrieved text, and returns the reply alongside the exact section anchors it used as citations.

When to use it

When you want an "Ask the docs" box on your developer portal that gives accurate, source-linked answers instead of hallucinated ones. Ideal for teams whose API reference and guides already live in ReadMe.

How it works

  1. 1A portal question arrives at the webhook with the user's query text.
  2. 2The query is embedded and matched against pre-indexed ReadMe doc chunks stored in Postgres via vector similarity.
  3. 3The top sections are passed to the model with a grounding instruction: answer only from supplied context, cite section slugs.
  4. 4A logic step checks whether retrieval confidence cleared the threshold; if not, it returns a "not covered" response instead of guessing.
  5. 5The endpoint returns the grounded answer plus the exact ReadMe section URLs that backed each claim.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HTTP webhookTrigger any URL on agent actions.
  2. 2
    Connect ReadMeAPI docs, changelog, auth.
  3. 3
    Connect OpenAIModels, embeddings, files.
  4. 4
    Connect PostgresAny Postgres URL — query, write, migrate.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
