## Guides

- Quick start — Install, call your first algorithm, and understand nulls and verdicts. — https://docs.thefintechbuilder.com/start/
- Plotting an indicator on a chart — Join indicator output to candles without shifting the series. — https://docs.thefintechbuilder.com/guides/charting/
- Wiring up a data provider — Write the one adapter you own, and validate at the boundary. — https://docs.thefintechbuilder.com/guides/data-providers/
- The five input shapes — Five input shapes cover all of it. Learn one and the rest follow. — https://docs.thefintechbuilder.com/guides/archetypes/
- What "verified" means — What the badges mean and where each example came from. — https://docs.thefintechbuilder.com/guides/verification/
- Using this library from an agent — Reading this library from an agent: what to fetch, in what order, and how far to trust it. — https://docs.thefintechbuilder.com/guides/ai-agents/
- The agent skill — Install the skill and let your coding agent use the library correctly. — https://docs.thefintechbuilder.com/guides/agent-skill/
- Concepts index — one guide per domain, explaining the subject rather than the API — https://docs.thefintechbuilder.com/concepts/

Verification tiers:
- verified — the worked example is the figure published in the algorithm's article, replayed
  and asserted by the test suite on every run. The arithmetic cannot drift without the build
  failing. Treat the numbers as reproducible.
- contract — the module loads, the entry point is callable and its declared signature matches
  the compiled code. The example is real captured output, but no independently published
  figure asserts it. Treat the shape as reliable and the numbers as unattested.

From the docs URL, mechanically:
  import subpath — swap the https://docs.thefintechbuilder.com/ prefix for fintech-algorithms/ and drop the trailing slash
  markdown page  — append index.md; same contract as the HTML page, a fraction of the bytes
