Firecrawl diagnosis

present

Auth

i
Firecrawl already has API-key auth and credit middleware. Budcle recommends adding x402 as a parallel paid path, not replacing the existing business model.
narrow

x402

i
Active x402 middleware exists on search. Core scrape, crawl, parse, and extract routes are still the obvious next paid endpoints.
missing

Marketplace

i
Budcle did not find Circle Agent Wallet or marketplace-facing docs: price, network, schema, response shape, and retry guidance.
missing

Receipt

i
Agent buyers need proof of what was paid for and delivered: amount, network, request hash, result hash, and provider job id.

What Budcle does

Scanrepo
Reads source files and route declarations from a local clone.
Scorereadiness
Detects auth, billing, rate limits, x402, Circle docs, schemas, and receipts.
Draftissue
Generates a maintainer-ready GitHub issue with endpoint-specific recommendations.
Approvehuman gate
No maintainer outreach happens without explicit human approval.

Signals

Routes
80 endpoint candidates detected in Firecrawl.
Billing
Credit and subscription primitives already exist.
x402
x402 dependencies and active middleware are present.
Receipts
Receipt/proof fields are not clearly documented.
Circle docs
Marketplace and Agent Wallet language is missing.
Schemas
Schema-like source signals exist, but paid endpoint listing metadata should be explicit.
Tests
Scanner, wallet wrappers, and demo probe all have passing tests.
Report
Markdown and JSON reports are generated from the ignored Firecrawl clone.

Maintainer draft

x402 scrape + docs + receipt

Add Circle Agent Wallet / x402 paid access for AI agents

Candidate endpoints: POST /x402/search, POST /scrape, POST /crawl.

First implementation: add POST /x402/scrape, return a 402 challenge, verify payment, run the existing pipeline, bypass credits for that paid call, and return receipt metadata.
