Documentation GitHub OpenAPI

Operations 6

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

POST /v1/xcalibur/echo/v2/compress Compress a prompt with ECHO v2 · Compress #

Ask an LLM

“Can I shrink a long prompt while keeping what matters for my task?”

“How do I set a target compression ratio and a minimum preservation score?”

Tell an agent

Compress this prompt with ECHO: {prompt}.

Compress {prompt} to ratio {target_ratio} for the task {task_query}.

GET /v1/xcalibur/echo/v2/health Check ECHO v2 compressor health · Health #

Ask an LLM

“Is the ECHO v2 prompt compressor up?”

“Can I health-check the compression endpoint before sending prompts?”

Tell an agent

Check ECHO v2 compressor health.

Ping the prompt compression service.

POST /v1/xcalibur/membrane/v2/classify Classify text as safe or unsafe · Classify #

Ask an LLM

“How do I check whether a piece of text is a prompt injection or otherwise unsafe?”

“Can I adjust the threshold and per-model weights of the MEMBRANE safety ensemble?”

Tell an agent

Classify {text} as safe or unsafe.

Run MEMBRANE on {text} with an unsafe threshold of {threshold}.

GET /v1/xcalibur/membrane/v2/health Check MEMBRANE v2 classifier health · Health #

Ask an LLM

“Is the MEMBRANE safety classifier available?”

“Can I health-check MEMBRANE without loading its models?”

Tell an agent

Check MEMBRANE v2 health.

Ping the safety classifier service.

POST /v1/xcalibur/verify/v2/attest Attest a data chunk belongs to a signed corpus · Attest #

Ask an LLM

“How do I prove a chunk is in a corpus and was signed by a specific post-quantum key?”

“Which signature algorithms does the attestation ensemble cross-check?”

Tell an agent

Attest chunk {chunk} against corpus root {corpus_root} with signature {signature_hex} and key {signer_pubkey_hex}.

Verify {chunk} is under root {corpus_root} via path {expected_path}, signed {signature_hex} by {signer_pubkey_hex}.

GET /v1/xcalibur/verify/v2/health Check VERIFY v2 attestation health · Health #

Ask an LLM

“Is the VERIFY v2 corpus attestation endpoint up?”

“Can I health-check attestation without loading the PQ libraries?”

Tell an agent

Check VERIFY v2 attestation health.

Ping the corpus attestation service.
