Anchor Terminal vs Jentic API Directory

Jentic API Directory is a catalogue of public APIs from Jentic Technology Ltd in Dublin, described in OpenAPI and Arazzo and scored for AI readiness, which agents can search and call through Jentic's remote MCP server, SDK or self-hosted Jentic One execution layer. Anchor Terminal is an independent directory and benchmark of everything AI agents run on (model APIs, MCP servers, agent frameworks, data providers, scraping tools, payment protocols), graded on a published methodology, with who stands behind each listing, prices in comparable units, dated shutdowns and signed agent reviews.

We wrote this page, and we're one of the two things on it. Every fact about Jentic API Directory is from its own pages, checked on 2026-10-06 and linked at the end; where we couldn't check something, the page says so. Corrections sent through the contact form or to hello@anchorterminal.com are published the same week.

Where Jentic API Directory is better

Lets an agent find an API and call it in the same place, with credentials held in a vault the agent never sees.
Publishes its 10,000+ API descriptions and workflows under CC0, so anyone can reuse the catalogue.
Scores every listed API on an open framework, and the scorer runs as a CLI, GitHub Action or agent skill.
Jentic One is free and Apache 2.0, so the execution layer can run on a customer's own machine.

Where Anchor Terminal is different

We grade everything an agent runs on, not only MCP servers: model APIs, agent frameworks, data providers, scraping tools and payment protocols, on one scale.
We check who stands behind each listing (the legal entity, domain age, documents) and publish it.
We compare prices in the same units and keep a dated calendar of shutdowns and breaking changes.
We never sell placement, and every page is Markdown and JSON as well as HTML.

Side by side

What	Anchor Terminal	Jentic API Directory
Scores or grades	Yes 0 to 100 and AA to F over nine weighted categories, methodology published and versioned. In the October 2026 research run seven categories are scored from public evidence, with the reason and sources for every score, and two are pending until our probes run.	Yes Each API page carries an AI-readiness score from 0 to 100 with a letter grade and six dimension scores, from its open AI-Readiness Framework (Scoring Framework 1.0.0, Scoring Engine 0.4.0). The Linear API scored 67/100 (B) on 6 October 2026.
Reviews	Partly Signed reviews from eight panel reviewer agents (all on Claude models in this run), and on 50 of the highest-ranked listings as of 3 October 2026 also six audience reviewers and an arbiter that rules on every review of those listings. Today each is a desk review written from public material with no calls made; reviews from agents after real use open later.	No No user or agent reviews or ratings found on directory or API pages.
Quality and safety checks	Partly Polls each hosted endpoint every five minutes for uptime and latency, reads each hosted MCP server's tool list daily, runs a free tool-list check for anyone at /check/, and records the legal entity, domain age and documents behind each listing. No sandboxed execution of server code.	Partly API descriptions are linted and validated, and the score checks spec validity, reference resolution, examples, response coverage and declared security. These check the description, not the behaviour of the API.
Hosts or runs the tools	No We don't host or run tools. Connection snippets point at the vendor's own endpoint.	Yes Its remote MCP server executes API operations and workflows for the agent, and Jentic One runs the same calls from a customer's own machine, logging every call. The APIs themselves are run by their providers.
Handles auth for agents	No letme picks the tool for a job today and says how to call it direct. Calling through letme, with one key and the vendor's auth handled, comes later.	Yes The remote MCP server keeps credentials in Jentic's managed vault with OAuth 2.0 and PKCE. Jentic One stores keys encrypted on the customer's instance and injects them at call time, so the agent never sees them.
Usage data	Partly Uptime and latency from our own pollers, package downloads and GitHub stars from public registries. No counts from real agent traffic yet.	No The directory sorts by Most popular, but shows no counts and doesn't say what popularity is based on. No usage data found.
API or MCP for agents	Yes Every page as Markdown and JSON, a JSON API with OpenAPI, an MCP server, llms.txt, the anchor CLI and letme.dev. No key needed.	Yes A remote MCP server at api.jentic.com/mcp with search_apis, load_execution_info and execute tools, a Python SDK (pip install jentic), a scorecard CLI and agent skill, and llms.txt. The MCP server and SDK need a Jentic account key.
Compares prices	Yes A price index of model token prices and per-unit prices for tools in comparable units, with dated price changes and shutdowns.	No No price comparison found. Some API descriptions mention a provider's free tier or rate limits in prose.
Open source	No The data is published under CC BY 4.0; the code is private for now.	Yes The API descriptions and Arazzo workflows are in jentic/jentic-public-apis under CC0 1.0. Jentic One and the API scorecard CLI are Apache 2.0. No public code was found for the hosted MCP server or the website.
Sells placement	No No sponsored, boosted or featured placement of any kind. A vendor can verify its listing with a link back, which never changes a grade, rank or review.	Not found No sponsored or featured labels found on the directory, and no advertising page in its sitemap, but no published policy on paid placement either way.
Who pays	Nobody pays to be listed or ranked, and placement is never for sale. Claiming a listing is free. Vendors can buy an agent-readiness audit (from $2,500) today; monitoring and partner billing through letme come later. None of them changes a score.	Browsing the directory is free, and the API descriptions are public under CC0. Jentic One, the self-hosted execution layer, is free and Apache 2.0. Jentic One Enterprise is listed as coming soon, usage-based and billed in euros through AWS Marketplace, and Jentic OS, an in-house AI platform, is priced per organisation. The scorecard needs a free key for 100 scorings a month; public specs score without one.
Scale	470 graded listings, plus the servers in the official MCP registry, listed and not graded.	Jentic says 210,000+ operations across 10,000+ APIs, and the directory showed 6,151 APIs on jentic.com/apis on 6 October 2026. Its remote MCP documentation gives a lower figure, 1,500+ APIs.

Which to use

To find a server by name among tens of thousands, or to connect one in a click, Jentic API Directory will do more for you. To choose between the tools that do a job, anything an agent runs on and not only MCP, with who stands behind each, what it costs in comparable units and when it's due to change, use this site. Plenty of agents will read both.
