Pricing
Everything Overwing sells, on one page.
Plans and top-ups are bought with a card on your dashboard. The done-for-you work is agreed by email and invoiced. Agents with a wallet pay per request and never need an account.
Guardrails
Monthly plans. Per organization, cancel any time.
Limits are evaluations per UTC day, shared by all keys in the organization. Every plan has every endpoint, custom rule sets, webhooks and the dashboard. The free plan needs no card.
Try every endpoint. Enough to wire up a prototype or run an agent's smoke tests.
Start freeFor a single product or agent in production.

Choose GrowthHigh-volume pipelines. Talk to us above this.

Top up by card. No subscription.
One-time packs. Credits are spent after the day's plan allowance and never expire. The first one is small on purpose: put a card on file, run it for real for a week, and decide.

Agent-ready, done for you
A fixed price, delivered as pull requests.

Free. The full report opens with a free account.
Enter a URL and Beacon says whether agents can find it, read it and use it, with the changes worth making first.
Agents with a wallet
Pay per request. No account.
Every paid route answers an unpaid request with a 402 and its terms, in USDC on Base over x402. Sign the payment, resend, done. The prices are small because the calls are small; an operator who wants a bill instead creates an account above.
