agnt-net

HTTP backend for the agnt agent runtime.

Provides multi-provider LLM inference (Ollama, OpenAI, Anthropic) with streaming SSE, retry with jitter, and default timeouts — on top of blocking ureq. No async runtime required.

[dependencies]
agnt-net = "0.2"

When to depend on this

Most users should cargo add agnt — the flagship crate re-exports this one under the net feature.

Depend directly on agnt-net when you want the backend layer without agnt-core's Agent loop — for example, if you're using the Backend struct as a thin streaming LLM client from some other framework.

What it provides

• Backend::ollama(model) — local Ollama via its OpenAI-compat API
• Backend::openai(model, api_key) — OpenAI
• Backend::anthropic(model, api_key) — Anthropic (with content-block translation at the wire boundary)
• Backend::with_timeouts(connect, read) — per-instance HTTP timeouts
• Implements agnt_core::LlmBackend

Security notes

• Backend::api_key is private. Manual Debug impl prints api_key: <redacted>.
• Upstream error bodies have Authorization / x-api-key headers scrubbed before bubbling up.
• HTTP redirects are enabled on the default shared agent but disabled in agnt-tools::Fetch (for SSRF reasons).
• TLS init is lazy and fallible via OnceLock<Result<_>> — no first-call panic.
• See the threat model.
