For agents and integrations

Built MCP-first. Every machine-discoverable surface our API exposes — at the well-known paths agents already look.

MCP most used

/mcp/

Model Context Protocol endpoint. SSE transport. Listed on Smithery.

OpenAPI

/openapi.json

Full machine-readable spec. 59 endpoints, 11 schemas.

Agent Card

/.well-known/agent-card.json

Agent2Agent discovery card. Lists capabilities + auth model.

llms.txt

/llms.txt

Plain-text summary for LLM crawlers. Tiered endpoint list.

Capabilities

Three capabilities, one API. Every response includes a confidence tier, an evidence tier, and structured caveats.

Chain Intelligence

Identify any address — entity, category, confidence, evidence tier. Batch up to 100 at once.

Transaction Verification

Confirm payments hit the right address and amount. Look up any txid for inputs, outputs, and fees.

Timestamping

Anchor any hash to the Bitcoin blockchain. Download cryptographic proofs. Verify existing timestamps.

Endpoints

Public beta: the full API surface is free right now. Billing stays wired for the post-beta access model.
