What is suap-iff-api?

A command-line guide for connecting to the SUAP IFF v2 API, the Instituto Federal Fluminense’s student-data service, using a student login.

Use it to obtain an access token and retrieve academic information such as school periods, student details, grades, and calendars.

It avoids common connection and authentication mistakes, such as using the wrong SUAP institution, API paths, or request format.

Token cost

What it costs to keep this loaded

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	$0.00102	$0.01656
Opus 5	$0.00051	$0.00828
Sonnet 5	$0.00020	$0.00331
Haiku 4.5	$0.00010	$0.00166

Security

Grade A, and why

suap-iff-api 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 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.

SUAP IFF API (v2 / django-ninja)

When to use

User has a SUAP IFF matricula + senha and wants data programmatically (boletim, períodos, dados do aluno, calendário).
User references suap.iff.edu.br/api/....

Key facts / pitfalls (learned the hard way)

The SUAP instance is https://suap.iff.edu.br — NOT suap.ifrn.edu.br. They are different instances with different data. The IFRN docs/swagger describe the SAME django-ninja API shape, but the user's data lives on the IFF instance.
Real API v2 endpoints are under /api/ensino/... (django-ninja), NOT /api/v2/edu/.... The /api/v2/... edu paths mostly 404.
The WAF blocks requests with no User-Agent → returns 403 Forbidden (nginx). ALWAYS send -H "User-Agent: Mozilla/5.0".
The auth endpoint does NOT use Basic Auth. Send username + password in the JSON body. (Sending Basic Auth or a user_token body first yields 422 "Field required".)

Step 1 — Get the token

curl -s -X POST "https://suap.iff.edu.br/api/v2/autenticacao/token/" \
  -H "User-Agent: Mozilla/5.0" \
  -H "Content-Type: application/json" \
  -d '{"username": "<MATRICULA>", "password": "<SENHA>"}'

Returns HTTP 200 with:

{"username": "<MAT>", "refresh": "<JWT>", "access": "<JWT>"}

Save it (e.g. /tmp/suap_token.json). The access JWT is what you send as Bearer.

Step 2 — Use the token

Authorization: Bearer <access>

Endpoints that WORK for a regular student profile (tested, real data)

Method	Path	Result
GET	`/api/ensino/meus-periodos-letivos/`	200, `{"results":[{"ano_letivo":2026,"periodo_letivo":1}, ...], "count":N}`
GET	`/api/ensino/aluno-matriculado/?matricula=<MAT>`	200, `nome, matricula, curso, campus, periodo_atual, nascimento, cpf, foto_base64`
GET	`/api/ensino/meu-boletim/{ano_letivo}/{periodo_letivo}/`	200 but `count:0` when no grades are posted (matches the empty UI)

Endpoints that do NOT return data for a regular student (tested)

Path	Result	Note
`/api/ensino/meu-calendario-academico/{ano}/{periodo}/`	404 on EVERY period	Not exposed for this profile — NOT a param error (schema wants integer ano + integer periodo_letivo)
`/api/ensino/meus-diarios/{ano}/{periodo}/`	404	Not exposed
`/api/ensino/meus-diarios-ead/`	401 Unauthorized	Needs a different scope (OAuth2TokenAuth/TrustedAppAuth)
`/api/ensino/meus-dados-aluno/`	500	Server bug on the IFF instance (not auth)
`/api/ensino/meu-boletim/...`	200 `count:0`	Empty when UI is empty (confirmed by user)

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.
