What this changes

Adding API docs && minor linter fix.

Closes #

Confirmations

Tick each box. An unticked box is not a rejection — it routes the PR to a
human instead of merging automatically, which is often the right outcome.

If a line does not apply to your change, tick it and say why underneath.

  • Unknown is reported as unknown. When the data is unavailable this
    returns UNABLE-TO-DETERMINE — not zero, not a default, not an estimate.
    An anchor that does not publish something is different from one that
    publishes something wrong, and the output says which.
  • Every figure came from a live source or a recorded snapshot. Nothing
    is guessed, interpolated, or averaged from other figures.
  • Tests run from testdata/snapshots, with no live network. Verified
    with make offline-test.
  • There is a negative test. A case where the code must fail or return
    undeterminable — not only the happy path. A test that cannot fail proves
    nothing.
  • decimal.Decimal for all money and rates. No float64 anywhere a
    price, amount or percentage is handled.
  • No new third-party dependencies.
  • No maintainer-owned file touched — nothing in dex/, sep38/,
    route/route.go, route/ladder.go, runstore/runstore.go, data/, or
    .github/workflows/.
  • make fmt vet test race lint is clean.

How you verified it

  • Reviewed the rendered markdown and compare against the live API responses.
  • Ran latest golang linter.

Why this template exists

This project's value is arithmetic correctness about money. A plausible-looking
PR that passes CI can still quietly change a published number, and the reader
of a published figure has no way to tell.

So the first review pass sits with you. The auto-merge gate lands changes it
can verify mechanically and hands everything else to a maintainer — the boxes
above are what it reads. Nothing here is ceremony: each line corresponds to a
failure this repository has actually had, or to an invariant in
CONTRIBUTING.md.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR revises the HTTP API reference for corridor, trend, asset, and health endpoints. It also replaces the README endpoint list with links to API and root UI documentation.

Changes

HTTP API documentation

Layer / File(s) Summary
Corridor and trend endpoint contracts
docs/api.md
The reference documents corridor parameters, response fields, fallback behavior, examples, trend limits, history behavior, and response schemas.
Asset and health examples with API navigation
docs/api.md, README.md
The reference adds asset and health examples and a contributing-guide link. The README links the HTTP routes and root UI.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 3deb8

The PR changes documentation and a minor lint issue, but several API examples and deployment explanations are inaccurate or invalid, and the root route is not linked consistently; this could mislead users, so merge is reasonable with explicit owner awareness and follow-up to correct the documentation.

Held for maintainer review. This is not a rejection — auto-merge only lands changes it can verify mechanically, and this one needs a human to look at:

  • no checklist items are ticked — the acceptance criteria are unconfirmed
  • checks are not green: golangci-lint (failure),build and test (failure)
  • CodeRabbit's review could not be parsed for a verdict, so it is not known to be clean
  • does not say which issue it closes, so its intended scope is unstated

Nothing further is needed from you unless a point above is something you can fix (an unticked checklist item, or a failing check). @0x6b64, thanks for the PR.

@Fury03 looks like the API docs are already added. I'm going to cancel this PR.

Addendum: Looks like the added API doc don't have the curl examples - so the respective issue is technically still opening. Reopening this PR and adding those.

589-589: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Update the measurement-status cause.

The row still says that the measure workflow cannot push. PR #380 merged on August 29, 2026 and changed the workflow to open measurement pull requests instead. Keep the frozen-history claim only if it remains current, but replace this outdated cause. Update the repeated wording near Line 35 as well. (github.com)

In `@README.md` at line 589, Update the measurement-status wording in README.md,

table, to reflect that the workflow now opens measurement pull requests rather
than failing to push; retain the frozen-history statement only if it is still
accurate.

Include the always-present trend fields in the example.

server/trend.go always serializes divergence_stats, but this 200 OK example ends after runs. The live response also includes asset identity fields and reference.scored_against. Add these fields, or mark the example as abbreviated. (wayfare-cdb9.onrender.com)

Regenerate and close the assets example.

The current response on August 31, 2026 reports USDC without peg, with can_be_destination: false, and includes an asset field. This example reports peg: "USD" and true, and omits asset. The JSON block also lacks the root closing } before the fence. (wayfare-cdb9.onrender.com)

PR Merge Manager — Auto-Merge Complete

  • CI: all 4 required checks green
  • Mergeable: no conflicts; branch brought current from main
  • Approvals: 0/0 met
  • Scope: documentation only — README.md and docs/api.md

One thing to fix on your next PR: the body says Closes # with no number, so GitHub will not link or close anything. The title references #321, but a closing keyword has to carry the number to work — and the merge manager deliberately does not infer linkage from a title, since that is how the wrong issue gets closed.

I verified the alignment by hand instead: #321 asks for copy-pasteable curl examples for every endpoint against the live instance, and this delivers seven covering the corridor endpoint (history-first, live=1, custom sizes), the trend endpoint, /api/assets and /healthz. That satisfies it, so I am closing #321 manually after this merges.

Merging now.
