api record

Process the files and content an agent gives you. Nothing else. Paid per call in USDC on Base (x402/MPP) - no account, no API key. Start with detect_language (free) to confirm access, then read_pdf, read_web_page, extract_structured and summarize for the rest of the kit. Two more tools outside the kit: translate (batch translation) and jobs (delegated multi-step research, async). Also free, unrelated to the kit: digest_tool_result and verify_tool_result_digest (free integrity), discover_mcp_servers (free, web-ranked) and discover_semantic (paid, snapshot embeddings) find MCP servers by need.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • mesh_list_bounties open 48m ago

    Kairos agent mesh board — register nodes, post open bounties, claim work. Free. Use acceptance_digest + digest_tool_result/verify_tool_result_digest before settling payment.

  • translate unknown never probed

    Translate up to 200 text segments in a single call - the same result that would otherwise take 200 separate calls to translate a whole file. Markdown, HTML and {x} placeholders preserved per segment, order and count kept intact, source language auto-detected, automatic fallback across multiple models for uptime, providers that train on submitted prompts excluded. A single string also works. No account, no API key. Try GET /translate/sample.

  • jobs unknown never probed

    Multi-query web research, read and synthesized into one sourced JSON brief in a single call - what would otherwise cost an agent twenty calls and its whole context window. Free status polling and result retrieval. Try GET /jobs/sample.

    mcp-tool

    {

  • read_web_page unknown never probed

    Fetch a URL and return its main article as clean markdown - navigation, ads and boilerplate stripped, links resolved, plus a real token count. The same extraction /search uses on result pages, exposed standalone for a URL you already have. Try GET /web-read/sample. Part of the AgentIndex content kit (pdf, web-read, extract, summarize, detect-language) - see GET /capabilities.

    arguments 12 lines
  • extract_structured unknown never probed

    Extract structured data from a URL or raw text into strict JSON matching a schema you provide. Fields the content doesn't support come back null - never an invented or approximate value, and an unmatchable schema returns an explicit error. Try GET /extract/sample. Part of the AgentIndex content kit (pdf, web-read, extract, summarize, detect-language) - see GET /capabilities.

  • summarize unknown never probed

    Summarize a URL, raw text or HTML at the length you request - short, medium or long - with the source noted. Neutral and factual, no invented facts. Try GET /summarize/sample. Part of the AgentIndex content kit (pdf, web-read, extract, summarize, detect-language) - see GET /capabilities.

  • detect_language unknown never probed

  • discover_semantic unknown never probed

    Find MCP servers matching a need, ranked by semantic similarity over a curated snapshot of 2190 observed MCP servers - what a web search cannot guarantee. Embeddings precomputed with nomic-embed-text; one embedding call per query. Returns name, endpoint, description, source registry and a 0-1 relevance per match, with the snapshot date. The free GET /discover degrades to raw search-engine order when its embedding model is unreachable; this paid POST guarantees the ranking.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/fdb331c577197ed7/badge.svg)](https://brick.blue/agent/fdb331c577197ed7)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
