Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00053 | $0.00472 |
| Opus 5 | $0.00026 | $0.00236 |
| Sonnet 5 | $0.00011 | $0.00094 |
| Haiku 4.5 | $0.00005 | $0.00047 |
Grade A, and why
openapi-trust scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s -X POST "https://trust.openapi.com/email-start/[email protected]" \ What it actually says
Openapi Trust
Base URL: https://trust.openapi.com — validity and trustworthiness checks to prevent fraud and bad data on your platform.
Authentication: Bearer token — see the openapi-auth skill.
All checks are async: POST creates the request (returns an id), GET /<type>/{id} retrieves the result. A callback URL can be supplied instead of polling.
Data checks
| Check | Create | Retrieve |
|---|---|---|
| Email (basic) | POST /email-start/{email} |
GET /email-start/{id} |
| Email (advanced) | POST /email-advanced/{email} |
GET /email-advanced/{id} |
| Mobile HLR (basic) | POST /mobile-start/{number} |
GET /mobile-start/{id} |
| Mobile (advanced) | POST /mobile-advanced/{number} |
GET /mobile-advanced/{id} |
| IP analysis | POST /ip-advanced/{ip} |
GET /ip-advanced/{id} |
| URL scan | POST /url-advanced/{url} |
GET /url-advanced/{id} |
Identity verification (IDV)
Three levels, each POST to create and GET /{id} to retrieve: idv-flash-start, idv-flash-advanced, idv-expert. Captured artifacts are downloadable per request: GET /<level>/{id}/front, /back, and (advanced/expert) /face.
IDV processes personal identity documents — handle results under GDPR, never store them in the repo.
Example
curl -s -X POST "https://trust.openapi.com/email-start/[email protected]" \
-H "Authorization: Bearer $OPENAPI_TOKEN"

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.

openapi-trust is a skill published in the GitHub repository openapi/openapi-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 53 tokens to every session and 472 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
