Agent-Friendly Services

English | 简体中文

Find services that let your Agent complete tasks, and use real tests to compare reliability, setup effort and cost.

We collect options for ordinary personal users and test them on real tasks. Browse the services below, open a name for its access requirements and sources, or follow a documentation link to get started.

Services (165)

Tokens and costs are means per valid trial, including successes and failures; invalid runs are excluded. Model costs use LiteLLM prices; ~ marks estimated service charges. — means no data.

Each service shows its most recently tested route with valid results; other routes and setup are in the service details. These are observations, not a ranking: compare only matching tasks and conditions.

What we tested and how

Task: Find flights from Milan to the Netherlands on September 25

September 25, 2026; depart from MXP, LIN or BGY and arrive at any passenger airport in the Netherlands; one adult, one-way, economy; connections allowed; use the service entry point specified for this trial.

Completion criteria: At least one itinerary matches the date, route and passenger requirements. Key details agree with the real service response obtained by the runner. Only search results are assessed, not the lowest price across all sites or successful payment.

Test configuration: codex-cli 0.153.4 · gpt-6-astra / xhigh · 10 min · 2026-09-07 (UTC) · No account or key supplied

Some early records lack environment details and await a controlled rerun.

What we tested and how

Task: Prepare a separate remote database for my personal todo app and verify adding, updating and reading todos after reconnecting

Synthetic test data only: id=1,title=Buy milk,done=false; id=2,title=Read book,done=false; id=3,title=Walk dog,done=true. Insert all three, then set done=true for id=2. A temporary database requiring no payment may be created; existing projects must not be modified.

Completion criteria: Data is actually saved and updated in the specified service's remote database. A fresh process reads back all three items with unchanged titles; only id=1 is incomplete, with three total and two completed. Evidence establishes an independent connection and remote execution. Credentials stay in private workspace files and must not appear in evidence or the final answer. Temporary resources are acceptable if their expiry is disclosed.

Task: I am upgrading a Python app to 3.13. Find out whether free threading is enabled by default, how to enable it, and what compatibility limits apply to existing C extensions, with official sources

Target Python 3.13; official sources under python.org. Discover sources through the search service assigned to this trial; directly reading the pages it returns is allowed. Do not answer from model memory or another search engine.

Completion criteria: All three questions are answered correctly and supported by official Python 3.13 documentation. At least two distinct official URLs appear in the specified service's real search response, with verifiable evidence. Fetching those pages directly is allowed; built-in web search may only locate service integration documentation and must not replace the tested search service.

What we tested and how

Task: Turn the action items in these book-club meeting notes into an online task table, give me its link, and tell me what is still unfinished and when each item is due

Book-club planning meeting, September 8, 2026: Lin Qing will confirm the venue by September 15; Zhou Zhou will prepare the reading list by September 16; Chen He will make the poster, originally due September 18. All three were unfinished during the meeting. Follow-up: Zhou Zhou has finished the reading list, and the poster deadline has moved to September 20. Everything else stays the same.

Completion criteria: The remote table contains exactly three actions with correct owners and final deadlines. The reading list is complete and the other two are incomplete. The answer links to the table and correctly lists the two unfinished items and their dates. The evaluator independently verifies the data through the service API. Fields and operation order are unrestricted; inserting the old state first or producing evidence files is not required.

Task: I want to sell an ebook titled “城市散步指南” for a one-time price of 12 USD. Set up its checkout page in the test environment and give me a link customers can open.

Ebook title: 城市散步指南; price 12 USD; one-time charge; quantity 1. Delivering the ebook file is not required.

Completion criteria: The evaluator independently reads the remote product, order or checkout resource and opens the returned link. The name, 12 USD base price, quantity 1 and one-time charge must match, and the page must allow proceeding to simulated payment. Any dynamic taxes are shown separately; successful payment is not required.
