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 | $0.00375 | $0.00375 |
| Opus 5 | $0.00187 | $0.00187 |
| Sonnet 5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade A, and why
jentic-public-apis AGENTS.md 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 9d 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.

For AI coding agents
When working with this repository:
-
Finding specs: Search
/apis/openapi/by vendor name. Each vendor folder contains versioned API specifications. Use/index/apis/openapi/{letter}/for alphabetical browsing. -
Finding workflows: Arazzo workflows are in
/workflows/and reference OpenAPI specs viasourceDescriptions. -
File formats: OpenAPI specs are OpenAPI 3.x (JSON or YAML). Workflows follow the Arazzo 1.0 specification.
-
Do not modify specs directly unless fixing validation errors. Submit issues for content changes.
-
Validation: Run OpenAPI specs through a validator before committing. Arazzo workflows should reference valid
operationIdvalues from their source specs.
Contributing
- New API specs: Submit via GitHub issue using the "Add API Integration" template
- New workflows: Use the "Generate Arazzo Specification" issue template
- Spec fixes: PRs welcome for validation errors or broken references

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.
