Ad library API

Competitor ads for your agent. Pay per search.

Callable now. Prices per search, as data.

What agents use it for.

  • See what rivals run.

    Let the agent pull the ads a competitor has live, with their copy and images.

  • Find the angle.

    Ask it to group the ads by message, so the gaps are easy to see.

  • Brief the next ad.

    Hand the findings to the next step: a better ad, made by the same agent.

Indexed. 13 more ad research APIs your agent can find.

Listed from their public pages so your agent can find them. Not sold through Sourcy, and a listing is not a partnership.

Questions. Answered plainly.

How does my agent pay for a search?

From its own Sourcy wallet. Before each call Sourcy checks your rules (a maximum per purchase, a daily cap and the categories it may buy from), then the agent pays the listed price per search with an x402 payment in USDC. Payments are in USDC on Base, which is real money.

What is the difference between indexed and callable now?

Indexed means Sourcy lists the provider from its public pages so agents can find it, but does not sell it. Each provider page shows how we read its terms; where they forbid resale, only the provider's written permission changes that. Callable now means Sourcy can make the call today and your agent pays for it per call. Indexed providers are not partners of Sourcy.
