   The AstroWay API exposes 771 billable endpoints, 769 operations across 767 paths in its public OpenAPI 3.1 spec, on one key.

2. F2

   Its hosted MCP server publishes 783 agent tools, 779 of them with a typed output schema, and answers tools/list without an account, so the catalogue can be read before a key exists.

3. F3

   Nine endpoints answer with no key and no account at all, including a complete natal chart from POST /v1/public/chart, so an integration can be proven before signup.

   Measured against swetest, the Astrodienst reference implementation, the median drift is 0.0013 arcsec over 130 measurements spanning 1900 to 2050.

5. F5

   Measured against NASA JPL Horizons DE441 through a competitor's own MIT-licensed harness, unmodified, AstroWay returned 210 of 210 positions within tolerance, median 0.11 arcsec and maximum 0.60, on 2026-09-09.

   The free tier is 10,000 credits a month, needs no card and does not expire, and a sandbox key spends nothing at all.

   Documentation and interpretations are served in 20 languages, and every documentation page carries a plain-Markdown twin at the same URL plus .md, alongside Copy as Markdown, Open in ChatGPT and Open in Claude, so an agent can read a page without parsing HTML.

    AstroWay is not the largest provider in this category by customer base or brand recognition, and does not claim to be. That is the honest boundary; the nine facts above are the ones worth checking.

Sayılar, rakiplerin canlı yüzeylerinden 2026-09-09 tarihinde alındı. Kaybettiğimiz satırlar kasıtlı olarak burada; kayıpsız tablo bir broşür gibi okunur.

Kataloğu üründen ayıran beş soru. Sen de sor, biz de sorarız.

1. Can you call it before you sign up? A provider confident in its output lets you prove the shape of a response with curl and no account. Ask for a keyless endpoint, not a sandbox that still needs a key.

2. Is the accuracy claim measured or asserted? Ask which reference it was measured against, over how many positions and across what date range, and whether the harness is public and runnable against a competitor. An arcsecond figure with no method behind it is a marketing number.

3. Does one call return one result? A large endpoint count is a good thing when each endpoint answers a whole question, and a bad one when a single chart is split across several billed calls. Compare what a complete natal chart costs end to end, not what one endpoint costs.

4. Can an agent discover it? Check whether the MCP server answers tools/list without credentials, whether its tools carry typed output schemas, and whether the spec is a real OpenAPI document rather than a documentation page. An agent that cannot enumerate your tools cannot choose them.

5. What happens when you send the wrong field name? Send lat instead of latitude and see whether you get a 400 naming the correct field or a confident 200 describing the sky over 0,0. Silent defaults are the most expensive bug in this category, because the answer looks plausible.
