# digiantnz (a2a-browser)

> digiantnz operates a2a-browser, a self-hosted, account-less, pay-per-query web retrieval agent in Christchurch, New Zealand, published as an A2A 0.3 agent card. It offers two skills — Web Search (SERP query with LLM synthesis and entity extraction) and Page Fetch (Playwright-rendered page fetch with a 50k character cap) — over a JSON-RPC 2.0 endpoint. A free tier (10 requests/hour, FIFO) is live; the paid tier (10 sats per search, 20 sats per fetch, 1,000 sat minimum, Lightning) is quoted live but marked alpha.

Generated by API Evangelist on 2026-09-19 from the provider's published agent card, /quote and /health endpoints and the artifacts in this repository. The provider publishes no llms.txt, OpenAPI, documentation site or MCP server; every statement below is traceable to a fetched URL.
