Tavily
A web search API that returns full-page text well, but usually buries the best result.
Content API that ranks badly and extracts well
- You need the answer-bearing passage in the payload, not just links or snippets.
- You can tolerate weaker top-3 ranking in exchange for more complete text extraction.
- You want an error-free search run across a fixed query set.
- You need strong top-3 ordering or the best ambiguity handling.
Our take
Tavily’s strongest trait in this run was extraction: the advanced tier reliably carried answer-bearing passages and materially outperformed basic on content completeness. But its ranking is still weak, especially at top-3, and advanced does not fix that — it is slower, pricier, and only clearly better on text coverage. If you want a search API that feeds an agent usable page text, Tavily is credible; if you need the supporting page to land near the top, it is a mixed fit.

Feature-by-Feature Breakdown
Live Web Retrieval and Ranking▾
Feature tested: Live Web Retrieval and Ranking
Result: Partial
Expected behavior: Tavily takes a plain-text query and returns ranked live-web results for agent use. In the 47 answerable queries, the supporting page usually appeared in the candidate set, though placement was weaker near the top of the ranking.
Test case: Text/code file → Text/code file
Input type: Text/code file
Input used: Input artifact (Text/code file): Ground-truth query set — QUERY-SET-ground-truth.csv
Observed output: Output artifact (Text/code file): Fixed 52-query ground-truth run across tavily/basic and tavily/advanced, with 0 errors. The export supports the reported retrieval metrics: top-1 13% in both modes, top-3 31.9% basic vs 27.7% advanced, and top-10 66% for both. — TAVILY-scored-run-export.csv

What changed: Text/code file transformed into Text/code file
Why it matters / Conclusion: Supporting pages usually appear in the candidate set, but Tavily is much less reliable at ordering them near the top.

Full-Page Content Extraction▾
Feature tested: Full-Page Content Extraction
Result: Passed
Expected behavior: Tavily returns usable page text rather than just snippets, with the advanced tier extracting more deeply. The evidence cites larger payloads and a clearer answer-bearing passage being carried into the returned content.
Test case: Text prompt → Text/code file
Input type: Text prompt
Input used: Input artifact (Text prompt): INPUT
Observed output: Output artifact (Text/code file): Q37 shows the content-depth win: advanced returned 92,217 characters and preserved all five GDPR Article 17(3) exceptions. Across the run, Tavily’s median payload was about 44,894 characters on basic and 49,982 on advanced. — TAVILY-per-query-output.md

Why it matters / Conclusion: This is Tavily’s best capability: it carries the answer-bearing passage into the payload, and advanced materially improves that coverage.

How it scored on the research's own criteria
The 11 evaluation dimensions from our hands-on research on Tavily, each judged from recorded runs on 3 test inputs — the same verdicts the ranking page ranks on.
held up partial failed not exercised by this input
| Criterion | Verdict | What the runs showed | Per input | Proof |
|---|---|---|---|---|
| Ambiguity handling | Weak2/5 | When names collide, it does not narrow to the intended entity early, so ambiguous searches remain risky. | open proof ↗ | |
| Answer quality (answer APIs) | Weak2/5 | It can answer some direct questions, but it also mixes bases and misses list items, so correctness is inconsistent on both arithmetic and completeness tasks. | open proof ↗ | |
| Citation accuracy (answer APIs) | Weak1/5 | With no source trail at all, there is nothing for a caller to verify, so the answer API fails its basic citation promise. | open proof ↗ | |
| Extraction quality | Strong4/5 | The payload usually contains the answer-bearing passage itself, and the richer tier meaningfully improves completeness instead of just repeating snippets. | open proof ↗ | |
| Freshness | Weak2/5 | It has some recent content, but the weak freshness hit rate and lack of date signals make it a poor choice for time-sensitive searches. | open proof ↗ | |
| Long-tail coverage | Mixed3/5 | It can reach niche material, but not reliably enough in the first three results to feel strong on specialist lookups. | open proof ↗ | |
| No-answer behaviour | Weak1/5 | It does not consistently back off when the question cannot be answered, and the confident fabrications are severe enough to count as a core failure. | open proof ↗ | |
| Relevance @ top-k | Mixed3/5 | It finds a supporting page often enough to be useful, but the right page usually appears only after the first few slots, so users still have to scan deeper than ideal. | open proof ↗ | |
| Cost per 1k queries | Mixed3/5 | The cheaper tier is reasonable, but the richer tier costs notably more without a matching ranking gain, so the value proposition is only middling. | open proof ↗ | |
| p50 / p95 latency | Mixed3/5 | The timings are measured and usable, but they are slow enough that interactive use will feel the delay, especially on the richer tier. | open proof ↗ | |
| Stability | Strong4/5 | Its overall rank tier is repeatable even if nearby competitors swap places, so repeated runs are usable despite some churn. | open proof ↗ |

Measured list pricing from the run
Two tested tiers; advanced costs 2× basic.
From the report: basic is listed at 1 credit / $8 per 1,000 queries, advanced at 2 credits / $16 per 1,000 queries.
