How this service works
Machine-readable contract for active Forest paid capabilities. Unsigned paid calls return HTTP 402 with a PAYMENT-REQUIRED x402 challenge.
Output
Returns a preflight report covering agentic-payment eligibility, pricing and budget signals relative to the provided max_charge_usd, and whether the supplied input is compatible with the Actor's public input schema — all derived from public Apify Store and default-build OpenAPI metadata, with no Actor execution or credit deduction.
Example use cases
Budget check before scraping job
“I want to run the apify/instagram-scraper actor with my hashtag input and a max charge of $2 — can you do a preflight to confirm the pricing fits my budget and my input is valid before I kick it off?”
Agentic payment eligibility screening
“Before my automation pipeline triggers the apify/web-crawler actor, check whether it's eligible for agentic payment and whether a $10 max budget is sufficient, using this input object: {"startUrls":[{"url":"https://example.com"}]}.”
Input compatibility validation for actor
“I'm about to run apify/cheerio-scraper with a custom input but I'm not sure my fields are correct — can you do a preflight against that actor to check input compatibility without actually starting anything or spending any credits?”
Technical details
Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/automation/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to gate an Apify Actor automation behind a pre-execution safety check — specifically to verify payment eligibility, ensure the budget cap is realistic, and confirm input compatibility before committing to a run. Prefer it over directly launching an Actor when cost control, input validation, or agentic-payment compliance is required. It is the right choice when you want a read-only, no-cost, no-side-effect screening step in an automation pipeline.
Side effects
- Actor identifier does not match the required pattern or is unknown in the public Apify Store
- max_charge_usd is zero or negative (schema requires exclusiveMinimum: 0)
- Actor has no public OpenAPI or Store metadata available, making preflight impossible
- Input object contains fields that conflict with the Actor's public schema, flagged as incompatible
- Service returns an error if the Apify Store is temporarily unavailable
- Ambiguous or private Actors may return incomplete eligibility signals
