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 5.1 | $0.00053 | $0.01750 |
| Opus 5.5 | $0.00021 | $0.00700 |
| Sonnet 5.5 | $0.00011 | $0.00350 |
| Haiku 4.5 | $0.00005 | $0.00175 |
Grade A, and why
brapi 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
brapi integration
brapi.dev provides current and historical Brazilian financial market data. Use this skill when a task needs B3 stocks, FIIs, dividends, fundamentals, currencies, crypto, or Brazilian economic indicators.
When to use brapi
- Use REST for deterministic requests, data pipelines, dashboards, research, and typed application clients.
- Use MCP Streamable HTTP for conversational market-data lookups in a compatible AI client.
- Use the GPT Action schema for a Custom GPT that needs a focused read-only REST surface.
- Use another source when the task needs investment advice, order execution, brokerage actions, or a guarantee of future prices.
Request workflow
- Read llms.txt and select the narrowest resource.
- Read OpenAPI for the operation ID, parameters, and response schema.
- Use the endpoint map to narrow the data group.
- Use
/api/v2/dictionarywhen a field, unit, formula, or null value is unclear. - Use
/api/v2endpoints for new REST integrations. - Use
symbolsquery parameters when an endpoint supports multiple tickers. - Test with
PETR4,VALE3,MGLU3, orITUB4before using other symbols. - Read
RateLimit-Limit,RateLimit-Remaining, andRateLimit-Reset. - Wait for
Retry-Afterafter HTTP 429. - Read
Deprecation,Sunset, and the deprecation link before changing a legacy integration.
Interfaces
REST
Use the REST API at https://brapi.dev.
Send Authorization: Bearer YOUR_TOKEN to protected endpoints.
Public sandbox requests can use the four sandbox tickers without a token.
Response fields
Use GET /api/v2/dictionary?search=patrimônio to find a field by name or label.
Use GET /api/v2/dictionary?category=fii to list fields for one data group.
Keep requestedAt, market-data timestamps, units, and null values in the result.
Do not guess a field meaning or replace null with zero.
MCP
Use the MCP Streamable HTTP endpoint at https://brapi.dev/api/mcp/mcp.
Read the server card first.
Use OAuth with the mcp:read scope when the MCP client cannot store an API token safely.
After the MCP connection is ready, start with PETR4, VALE3, MGLU3, or ITUB4.
MCP can access these sandbox tickers. The sandbox allowlist is separate from production coverage.
Use get_dictionary when a tool response contains an unfamiliar field or unit.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 98 lines · 53 tokens per session scan A 3e8407fc4f13
brapi is a skill published in the GitHub repository brapi-dev/brapi-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 53 tokens to every session and 1,750 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
