Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00017 | $0.00333 |
| Opus 5 | $0.00009 | $0.00167 |
| Sonnet 5 | $0.00003 | $0.00067 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
update-apis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Read docs/architecture.md → "The public API (/v3)" first: it holds the naming contract (camelCase parameters,
snake_case output everywhere except Shapefile), the DTO layout in app/models/api/, and the StreamingApiType
serialization shape. .claude/rules/api.md is the short version.
The set of updates that are likely to be involved:
- Updating the database queries to incorporate the new/updated data (in the
app/models/files). The DTO definitions themselves belong inapp/models/api/*ApiModels.scala, not in the*Table.scalathat produces them. - Making sure the API is updated for every output file type it serves (JSON, CSV, GeoJSON, Shapefile, GeoPackage),
with the serialization on the DTO (
toJson/toCsvRow,csvHeaderin the companion). - Updating the relevant documentation in the
app/views/apiDocs/files and the matchingpublic/js/api-docs/*Preview.js. - Updating or adding the functional spec in
test/controllers/api/.
A few things to keep in mind:
- Combine common code where it makes sense to do so; reuse
ApiModelUtilsrather than re-rolling CSV/GeoJSON logic. - Run the queries both before and after your updates to check for any regressions.
- v3 is a preview surface: breaking changes are made in place rather than minting a new version.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

update-apis is a skill published in the GitHub repository ProjectSidewalk/SidewalkWebpage (105 stars, last pushed today), licensed MIT. It adds 17 tokens to every session and 333 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
