## Free search access: allowances, cards and limits

Official terms checked 20 September 2026 (UTC). TinyFish offers a zero-priced Search endpoint. The other providers offer credits for metered endpoints. The quality table below compares their measured configurations; throughput on free accounts can differ from benchmark conditions.

__Six providers with documented free access · credits and request caps are different limits__
| Provider | Free allowance | Renewal | Card required | Limits and billing unit | After the allowance | Official source |
| --- | --- | --- | --- | --- | --- | --- |
| TinyFish | $0 per Search request | Rate-limited access | No | 30 requests/minute; 500/hour. Search works at a $0 Wallet balance. | Search remains free within these caps. Agent and Browser have separate charges. | [Pricing & terms ↗](https://www.tinyfish.ai/pricing) |
| Exa | $20 signup credit + $10/month | Monthly credit plus signup grant | No | Starter lists 10 search queries/second. Calls consume dollars at the chosen endpoint’s rate. | Paid usage follows endpoint rates; Search is currently listed at $7/1,000 requests. | [Pricing & terms ↗](https://exa.ai/pricing) |
| Tavily | 1,000 credits/month | Monthly | No | Basic uses 1 credit/search; advanced uses 2\. Other endpoints share the credit balance. | Pay-as-you-go: $0.008/credit. Basic: $8/1,000; advanced: $16/1,000 at that rate. | [Pricing & terms ↗](https://docs.tavily.com/documentation/api-credits) |
| Parallel | $5/month for eligible organizations | Monthly; unused credit expires | Yes, for monthly credits | One allowance per eligible organization/card. Marketplace and postpaid organizations are excluded. | Usage above the credit is billed at standard rates. Mode and other API usage determine capacity. | [Pricing & terms ↗](https://parallel.ai/blog/free-tier-parallel) |
| Brave Search | $5/month | Monthly | Yes | Search lists $5/1,000 requests and 50 queries/second. $5 covers 1,000 Search calls if used only there. | Search is metered at the listed request rate. Check the account’s current billing settings. | [Pricing & terms ↗](https://brave.com/search/api/) |
| Firecrawl | 1,000 credits/month | Monthly | No | 500 searches at 2 credits per 10 results; 10 search requests/minute. Scraping uses the same balance. | Hobby: $19/month billed monthly for 5,000 credits. Additional scrape features consume extra credits. | [Pricing & terms ↗](https://www.firecrawl.dev/pricing) |

For ongoing zero-priced search calls, start with TinyFish’s limits and measured quality. For a small project, recurring credits can make a different provider practical. Paid configuration prices remain visible below so you can compare the cost when your usage grows.

## Choose the best web search API for your application

### Start with the kind of free access you need

TinyFish lists Search at $0 per request within minute and hourly caps. Exa, Tavily, Brave, Parallel and Firecrawl offer allowances that reset monthly. A dollar allowance buys different numbers of requests at different modes; shared scrape and research usage can consume the same balance. Check the exact endpoint before estimating capacity.

### Choose accuracy first, then check your free capacity

The table ranks search configurations from the six providers whose free access is documented above. Accuracy measures whether search results support the correct answer on the same questions. These benchmark runs measure endpoint quality; account-tier throughput and free-credit exhaustion are separate buying checks.

### Budget searches and model calls separately

Free search removes the search-request charge within the offer’s limits. Your model, hosting and optional scraping still have their own costs. For an agent that searches four times per question, 1,000 search requests cover roughly 250 questions before retries. Count actual calls and cap concurrency to fit the documented rate limits.

### When to move to paid search

Move to a paid plan when your allowance, request rate or required support becomes the constraint. Compare the exact mode’s paid rate with its measured accuracy and latency. The benchmark table preserves recorded prices; the free-access table links current official terms and states when they were checked.
